Safe In Their Care

Summary: While on shift at the firehouse, a severe migraine hits you hard—accompanied by the dreaded aura and vomiting. Matt and Kelly know exactly how to help, offering support and reassurance when you need it most. Though you insist you’re fine, they refuse to let you push through the pain alone, guiding you through the worst of it and making sure you rest.

Warnings: mentions of vomiting, nausea, needles and injections

It started as a dull throb behind your eyes, a familiar feeling that you tried to ignore. You had learned to push through migraines on shift before—after all, being at the firehouse was no place to show weakness. But today, the pain crept in faster than usual, quickly escalating into something unbearable.

The flashing lights and the sounds of the firehouse faded into the background as your vision started to distort. It was a warning sign that you knew all too well: the aura. Your hands shook as you tried to keep your composure, but it was becoming increasingly difficult. Each throb in your skull felt like an electric pulse, and the nausea was a relentless wave that threatened to overwhelm you.

You staggered to the back of the station, hoping to escape to a quieter area. But as you walked, the world around you spun—spinning faster than you could control. Panic crept in as you fought to steady yourself, but it was a losing battle. You could feel the sweat on your skin, the tightness in your chest. Then came the dreaded sensation of vomiting—your stomach turning in knots before you finally doubled over.

“Y/N!” The voice that broke through the haze was Kelly’s, followed by the sound of Matt’s heavy boots pounding toward you.

You managed to look up just as they reached you, concern written across both of their faces. Kelly was the first to reach you, gently guiding you into a chair while Matt held your shoulders steady, trying to keep you from collapsing under the weight of the pain.

“Hey, hey,” Kelly said softly, his hand warm and steady on your back. “Breathe. We’ve got you.”

You blinked up at him, the world still swaying and your vision a blur, but you didn’t want to show how bad it was. “I’m fine, Kelly. It’ll pass. I just need a minute.”

Matt crouched down in front of you, his hands on your knees. He was more than familiar with migraines—he knew how they could escalate in an instant, how they could leave you feeling completely helpless. “Y/N,” Matt said gently, his voice firm yet comforting, “I know it’s tough, but we’re not letting you push through this alone. It’s not worth it.”

You shook your head, trying to argue, but the words fell short. The aura was still making everything feel out of focus, and the nausea continued to roll in waves. Your stomach churned with each passing second, and the dizziness made it impossible to think clearly. You took a deep breath, still unwilling to admit just how bad it had gotten.

Matt didn’t push back. He knew you hated when things got out of control, but he also knew the signs. He looked at Kelly, and the two of them exchanged a silent understanding. Kelly nodded, then turned back to you.

“Y/N, you need to take your sumatriptan,” Kelly said, his tone calm but insistent. “It’ll help. We’ll make it as easy as possible for you, but you have to take it now.”

You looked at the small injection in Matt’s hand, the familiar sting of the needle already making your body tense. You hated the idea of taking it, the vulnerability it made you feel, but deep down, you knew it was the only thing that would give you any relief. You gave a reluctant sigh, not wanting to admit how bad the pain really was.

“Fine,” you muttered, holding out your arm, not meeting either of their eyes. “Just… just get it over with.”

Matt’s expression softened as he prepared the needle, then gently administered it into your arm. The sting was sharp, but it was over quickly. He didn’t say anything at first—he just sat back and rubbed your shoulder, letting you adjust to the sudden wave of warmth that came with the medication.

“Thank you,” you whispered, your voice strained and hoarse from the vomiting. You hated that you needed the help, but it was a relief to know that Matt and Kelly were there, that they wouldn’t let you fall apart alone.

“Of course, Bug,” Kelly said, his voice soothing as he ran a hand through your hair. “We’re here. You just need to rest. It’s okay to take a break.”

Matt stood up slowly and gently helped you to your feet, his hand never leaving your back. “You’re not going back to work, Y/N. Not while you’re like this. Let’s get you to my office so you can rest.”

You tried to protest, tried to tell them you were fine, but your body wasn’t listening. The medication was kicking in, but it hadn’t fully taken hold yet, and the pain was still strong. Kelly and Matt didn’t give you the chance to argue. They guided you to Matt’s office, a quiet, dimly lit space away from the chaos of the firehouse. Kelly helped you settle into the worn-out couch, his touch gentle as he tucked a blanket around you.

“You’re going to rest, okay?” Matt said, sitting beside you. His eyes were soft with concern. “I’m going to stay right here with you. You don’t have to push through this on your own.”

You closed your eyes, trying to block out the world. “I’m fine,” you muttered again, but the words were weak, and you knew they weren’t true. You could feel the exhaustion creeping in, the relief slowly beginning to take hold.

Kelly smiled, his voice warm as he gently rubbed your back. “We know. Just close your eyes. We’ve got it from here.”

Matt pulled up a chair beside the couch, never taking his eyes off you, staying vigilant but calm as he kept a hand on your arm. The minutes passed slowly, but gradually, the world started to return to its usual clarity. The sharp pain in your skull began to dull, replaced by a softer ache. The nausea, too, began to subside.

“Better?” Matt asked quietly after some time, his voice full of that unspoken care you had come to rely on.

You nodded, your body feeling lighter, the worst of the migraine now behind you. “Yeah,” you whispered. “Much better.”

Kelly’s hand stayed resting on your shoulder, his touch still warm and comforting. “You just needed a little time, Bug. You don’t have to go through this alone.”

Matt smiled softly, his gaze steady on you. “You’re strong, but it’s okay to lean on us when it gets tough. We’ll always be here.”

As the pain receded and your body began to relax, you allowed yourself to sink into the softness of the couch, comforted by the presence of Matt and Kelly. The firehouse might be busy, chaotic, and loud, but in this small, quiet space, you knew you were safe. You weren’t alone. And for once, that was enough.

Guys I’m back kinda, I thought I’d share this - since I haven’t been all that active I’ve been back at work. Only a month to go! But I hope you all enjoy this and thank you for all of the continuous love on my other Chicago fire fics! 🫶🏻

Matt Casey and Wife Reader

There’s a big crash and 51 gets called out to it and they find Matt’s wife’s car in the crash all smashed up and Matt’s pregnant wife unconscious and hurt inside with their toddler son Jack who is crying. So Matt and the 51 guys do their best to save the family of their own Captain.

Warnings: Car crash, canon-typical injuries, death.

A/N: Once again, one month later. Life is not vibing right now but it's okay. I hope anyone who celebrated Eid had a wonderful time! very belated Eid Mubarak.

I hope this suffices and meets your expectations. I know this was sent ages ago and I apologise for the very long wait, I've just had zero inspiration and drive to write. This month has been very stressful with exams but please do enjoy!!

Matt was angsty and restless ever since his 24-hour shift started. There was no reason as to why he was but no matter what he did, he couldn't get rid of the feeling. He tried sleeping it off, eating lunch and even calling you when they weren't busy, but he still felt unnerved.

Just as he was about to text you, wanting to quickly check in again, something he'd been doing much more regularly now that you were pregnant along with looking after your toddler, the bells rang.

Internally groaning, Matt tried ignoring whatever his body was trying to scream at him and rushed towards the trucks, everyone quickly getting their uniform on before jumping into their 'allocated' seats.

It didn't take too long to arrive at the scene, the mess being much larger than what they anticipated. But maybe this was good, the more work he had to do, the less time he had to himself and to contemplate on whatever was bothering him today. The scene was one large mess, cars mangled together for what seemed like miles.

Maybe this was the exact distraction he needed.

Boden began shouting orders, Kelly and him following as they too started to delegate roles between their own respective crews. With equipment in hand, everyone scattered to hopefully start minimising this massive mess. From the looks of it, several casualties were to be expected with many more injured.

Squeezing between cars, Matt looked through broken windows looking for anyone who was stuck or left behind, also keeping an ear out for any shouts of help. Only, he didn't hear anyone shouting for help, but he heard crying.

It wasn't piercing like a newborn; he knew that sound well, but it sounded like a child and that made his heart skip a beat. Ever since Jack was born, calls involving kids become infinitely worse to handle.

Running towards the crying, Matt held his breath in an attempt to hear better, but his feet suddenly came to a stop before his brain could even register what was happening.

That was your car that along with many others, was laying on its side.

Matt vividly remembered you telling him your plans for the day this morning while he got ready for work and you fed Jack. You were going to run to the office to pick up some bits before taking Jack out to the trampoline park with some of his friends and other mums.

Apparently, you never made it to the park.

The crying continued and everything came crashing down on him. It wasn't just any crying, he recognised it easily now that he was closer.

Rushing forward, Matt ignored the broken glass and dropped to his knees as he looked for his family.

He saw you first. Your eyes shut, blood trailing down your forehead, head slumped to the side and seatbelt digging into your body that sat unmoving.

He then looked in the back where the crying hadn't stopped, Jack's eyes screwed shut as he wailed, the occasional 'mama' audible between cries.

"Jack. Daddy's here Jack." Matt forced out, his throat constricting at the sight of his hurt family. First things first, he had to get Jack settled and out the car before he could get you out. "Jack, it's me."

His crying calmed down, eyes peeling open as his crying slowly eased when he found his father.

"Are you okay Jack? You hurt anywhere baby?" Matt asked, easily taking apart the door and getting in besides the car seat.

"Daddy." Finally having one of his parents with and responding to him, Jack started to cry again, making grabby hands towards Matt as his words went through one ear and out the other.

"It's okay. I've got you now." Matt cooed, unbuckling from his car seat and before he could do anything, Jack launched himself into his dad's open arms.

A small oof was forced out of Matt from the sudden force of Jack catapulting into him. But he tightly wrapped his arms around his toddler nonetheless, his chest somewhat lighter with his boy safe in his embrace.

"Matt, is that- oh shit." Kelly swore as he rounded the car, eyes going wide as he saw father and son.

"I'm taking him to Sylvie." Matt started, holding out Jack for Kelly to take so he could jump out of the car that was still on its side and creaking with every movement he made. Without another word, Kelly took his godson and waited for Matt to get out before handing him back over.

"I'm waiting on Cruz and Violet." Kelly said, his eyes remaining on the father and son duo, both of their arms wrapped tightly around the other in fear of being separated again. "We've got Y/N, I promise."

Matt didn't even bat an eye when his best friend made a promise, one of which they were never allowed to make as first responders.

With another glance at your unconscious body, Matt held his breath as he stepped away, his heart constricting when Jack realised what was happening, trying his best to not crumble at his toddler's cries for his mama who wasn't responding to him.

*****

Somehow, Jack came out of the crash relatively unharmed besides the few cuts and bruises. He was for sure to be sore for the rest of the week. You however, your physical state was harder taking into account your pregnancy and they could only do so much in an ambulance.

It took them some time, but they had gotten you out safely, laying down still unmoving on a backboard. There were two of you but only one of him and with the way Jack was gripping his uniform jacket, there was no way he could leave, especially when he'd whimper at any movement he made, in hear his father would leave him alone.

Boden had dismissed him from the scene, giving him the permission to ride in the same ambulance as you, Jack not once letting go of him.

The hospital was in its usual disarray but Matt's concern was so high for you and your unborn child that he didn't even bat an eye at all the doctors and nurses running around ragged.

Natalie had seen you immediately, wasting no time in checking your physical state before scanning your stomach.

Matt could've cried when Natalie confirmed there was absolutely no harm caused besides whatever had been inflicted upon you.

After a few more checks and tests, Natalie turned to him with an understanding smile.

"She most likely has a concussion, some bruises that will definitely be sore for few weeks but nothing internal or severe."

Matt sighed in relief, his entire body deflating as he slumped back in the chair, Jack moving with him from his now permanent position in Matt's lap.

"You can go sit with her."

And so he did without any further prodding.

Walking back into the room, Matt looked your unconscious figure over, confirming with his own eyes that everything was indeed fine and you were in fact healthy.

Manoeuvring the sleeping toddler in his lap, Matt sat down and placed your hand in his. His fingers gently caressing the scars and scratches on your hands, knuckles raw and red from the sudden impact.

Closing his eyes, Matt lightly pressed a kiss into Jack's hair, his eyes stuck on you.

His little family were all safe and with him here where he wouldn't let them out of his sight. If his throat got tight and his eyes watery, glistening in the bright hospital lights, no one saw.

No one would blame a man who almost lost all his family before he could even meet its final member.

Matt sniffled, shaking away such unnecessary deprecating thoughts. You were all here now, unharmed for the most of it, and you were back with him. That was all that mattered.

Summary: Y/N struggles with demands from a friend, and Matt solidifies the fact he will always be in her corner.

Word Count: 2.6K+

Warnings/Tags: toxic friendships

A/N: something bugged me recently so here’s a fic! This can be a bit of a controversial take based on the context but didn’t want to go full on in the fic so anyway~ just needed to get this off my chest.

“Baby, I’m…” Matt’s voice drifted off slightly before he completed his sentence, “…home.”

You could only imagine being Matt and coming home to this sight.

You were seated in the middle of the living room in the apartment you shared with Matt, surrounded by yarn, bits of fluff stuck in your hair, sheets of sketched designs strewn across the floor.

You could feel the panic rise even more as you took in the look on Matt’s face. Especially since you couldn’t read his emotions as the anxiety clouded your brain.

“Matt, I…” 

You couldn’t continue as you felt your chest tighten just a little, the anxiety and panic clawing its way to the surface and rearing its ugly head at you. 

This had all started with Amy.

Amy.

She was a friend you’d known for almost your entire life. You’d laughed together, cried together, dreamed about the future together and talked about those dreams. Along the way, you both had stumbled, you saw less of each other, and Amy reached out less, sometimes forgetting to respond to your messages. Despite what everyone told you, you convinced yourself that it was just how life was and you made excuses for Amy’s growing absence in your life.

Then, she’d reached out to tell you she was getting married.

You felt the excitement first, remembering it like it was yesterday, how you had both talked excitedly about how you would be each other’s bridesmaids. It wasn’t a conscious memory, but it was like your brain had pulled it up, triggered by the words Amy was saying.

You didn’t even feel any apprehension when she asked if you would make the flowers for the bridesmaids. You weren’t too confident because crocheted flowers weren’t really your thing. In fact, you’d only tried it out once. So you’d told Amy you’d give it a shot, make a prototype and see how it went.

You could tell Matt hadn’t been thrilled with the idea but he didn’t say much, only offering opinions when you asked for them and keeping most of his comments focused on the task rather than Amy. Yet, you knew he was holding back. You knew Matt didn’t feel great about Amy, mainly because of the things he’d witnessed, in particular, the way she blew back into your life when it was convenient for her.

But things had been going downhill ever since you’d made the first prototype. She kept changing what she wanted, and even you were getting a little frustrated, mixed with a desire not to disappoint her.

So, having Matt stand there with a surprised look on his face in the middle of an extremely messed up living room only added to your current panic.

You felt your breath quicken and very soon, Matt’s figure was clouded by the tears you didn’t realize had pooled behind your eyes.

Without saying anything, Matt dropped whatever was in his arms, heading straight for you and folding you nice and tight into his arms. 

“Y/N, it’s okay. It’s okay.” Matt whispered quietly, and you felt the rumble of his chest before your breathing slowly evened out once again.

Matt didn’t move immediately, but his fingers brushed off the residual tears that were rolling down your cheeks.

“Sorry, I don’t…” 

Matt just tightened his arms a little and pressed a kiss firmly to the top of your head.

“Sorry,” You mumbled, scrubbing off the remnants of tears on your cheeks before glancing up at him.

Matt shook his head and leaned down for another kiss and you leaned into his embrace, temporarily forgetting about the mess in the living room.

By the time you woke up the next morning, there was barely a trace of the mess last night. The yarn was back in the boxes you had in the corner of the room and the half done flowers were laid out neatly on the kitchen counter.

No one else would have guessed what had happened the night before. 

Matt was almost on his way out, draining the last sip of his coffee and smiling as you walked into the kitchen.

He didn’t ask but just studied your face for a little longer than usual.

You smiled back at him and nodded. “Go on, I’m fine.” You assured him, even though you stepped toward him and nuzzled your face into his shoulder.

Matt pressed you lightly against him and pressed a kiss to your temple.

“You know where to find me if you need me.” Matt whispered gently into your ear.

You smiled into his shoulder with a small nod before both of you pulled away and you let Matt go before he was late for shift.

Even as the door closed behind Matt, you felt it rear to the surface. This time, the feeling was different. It wasn’t even residual anxiety from the night before. You couldn’t put your finger on it but it was bugging you.

Deciding that it might be good to have a change of pace, you grabbed the materials you needed, slung the tote bag over your shoulders and left the house, figuring you’d find a nice cafe to work out of.

So you did and you had been right. A change of environment had done wonders for you and you finally had a final prototype for the new flower idea Amy had had.

You snapped a photo and sent it to Amy, quoting as reasonable a price you could for the materials and stitches. You even gave her what she called a ‘friend discount’. 

But for someone who sometimes took days to respond to you, her response was quick now.

It’s a little out of my budget.

Thereafter, she proceeded to give you a price she was willing to pay that was such a lowball, you almost dropped your phone.

It took you a moment and another few breaths to register that feeling bubbling up in your chest now. You recognised it as a more intense version of what you had been feeling that morning. Now, you could indeed put your finger on it - Disappointment.

It was disappointment that raged within you. Especially when you’d always treated Amy like a sister.

You felt it swell as you thought about the effort you’d put in all these years, even just the effort in designing flowers she would want for her wedding, and then you remembered the many times she’d blown you off, and when she’d been dating that toxic ex of hers and had cut you out of her life for more than a year until the break up.

Resisting the urge to send her a scathing reply, you stuffed the rest of your belongings into your bag and headed out the cafe, only realizing where your legs had taken you when you looked up at the firehouse in front of you.

The trucks were all parked which meant everyone was around. 

Now that you were here, you had second thoughts and you were about to retreat, thinking you’d talk to Matt during breakfast the next day when you heard an all too familiar voice call out to you.

“Y/N?”

Of course today would be the day Kelly came to get something out of his car.

“Hey, Kelly.” You greeted back, your voice sounding weird even to you.

Kelly either didn’t notice or chose not to mention it. He just smiled and nodded. “Come on, Casey’s in his office.”

You didn’t protest, letting Kelly lead you in as if it was your first time visiting the firehouse.

Everyone called out toward you with smiles and you waved back at them as you made your way through the common room and toward Matt’s office.

“Look who I found,” Kelly called with a casual rap at Matt’s door.

Matt sat up, glancing at you before smiling. “Thanks, Sev.”

Kelly winked, more at you than him, before leaving the both of you alone.

Matt got up to close his door and glanced at you. “Everything okay?”

After all, you rarely came to the firehouse without a call beforehand. Usually, you were worried about being in the way so you only came to bring them some food, especially when you’d heard it was a difficult shift.

You nodded. “Nothing big, I just…”

You held back a heavy sigh and just handed him your phone.

Matt’s eyes moved across your phone screen as he read the message and you could see the slight darkening of his expression, even though he was trying to keep it under control.

Matt looked back up at you and handed your phone back to you. “So what are you thinking?” Matt asked.

You shouldn’t have been shocked by Matthew Casey’s complete focus on your feelings, but you couldn’t help the little jolt of warmth that still filled you even though you and Matt had been dating for a long while.

You shrugged and Matt gave you a look, which just made you smile.

“Fine, I’m annoyed. It’s like every single moment with her has been flashing in my head since I got that message and the annoyance has been piling. That’s why I haven’t responded.”

“Go for it, babe.” Matt said, matter of factly.

You glanced at him with half a smile.

“You deserve to be treated with respect and I think it’s high time someone told her. And if you don’t want to do it, I’d be happy to.” Matt said, his voice laced with a subtle protectiveness.

You pulled him toward you, just so you can lay your head against him and smiled. “Thank you.”

The conversation had gone about as you’d expected. 

You tried your best to keep your side as light as possible while remaining firm, and ultimately, the decision had been for you to try to do little flower wristlets for Amy’s flower girls, instead of a large order of flowers.

You weren’t too thrilled to do it anymore, but a part of you felt obliged to, so you’d agreed.

It was only two days later that you had run into Amy when Matt had taken you out for dinner.

“Hey, I…” You greeted her even from a distance, trying to keep things as normal as possible.

But you didn’t miss the look on her face as she turned away, as if she was pretending not to see you.

Instinctively, you glanced up at Matt, your expression one of disbelief.

Matt just squeezed your hand but you could see the strain lines on his face which were a clear telltale sign he was using all his effort to hold back.

Matt was trying to reassure you, but the only thing you felt now was anger.

There was no more second-guessing on your part about whether you had been too harsh or too mean. You knew the answer. 

You were about to open a small side business for your crochet. All your friends, including Amy, knew that.

In fact, anyone who tried to ask you to make something for them had always offered you more than what you quoted, reminding you that friends didn’t take each other for a ride.

Amy was the exact opposite and what really grinded at you was the fact that she thought she was well within her rights to be angry at you.

You were a little confused but the anger had swallowed it all up.

“You want to go elsewhere?” Matt offered.

You glanced up at him.

If this had been anyone else, it might have made you avoid the situation altogether. But right now, the indignant feeling had turned into anger.

“Why should we? You put in so much effort into trying to get a reservation here. Let’s just have a good dinner.” You answered.

 This felt like a huge breakthrough moment for you, even Matt felt it - you could do anything you had set your mind to. 

You sat down with Matt in a corner of the restaurant, pretty sure that Matt had used one of his superpowers to get the both of you a great table and you turned your back on Amy, focusing all your energy and attention on the one person who was worth it.

Once the appetisers were served, you’d thrown Amy to the back of your mind, sinking into Matt’s company and enjoying the date night that both of you deserved. 

It was just as the both of you had stepped out after paying the bill when someone grabbed your arm. 

“Food’s great here, isn’t it?”

You blinked back in disbelief at Amy, who was smiling as if nothing had happened.  

It would have been much better if you hadn’t met her in front of the restaurant earlier. Now, you were just wondering what the hell she was doing.

Matt didn’t say anything, just stood by your side and waited.

“What are you doing?” You asked, unable to hold it back any longer. There was a slight tremor in your voice that no one but Matt picked up on. 

The saddest part was Amy used to be able to. Now, she just didn’t care.

That realization hit you hard but also allowed you to look her straight in the eye.

Frustratingly, Amy was staring at you as if she was confused by your question.

When you didn’t offer her any explanation, she swallowed and spoke, “Come on, Y/N. I told you I was on a budget. You’re my friend, I didn’t expect you to try and profit off my wedding.”

You glanced up at Matt just a little and he merely nodded in encouragement.

“Profit? Amy, you agreed to pay! You are literally the only person that has lowballed me for anything crochet related. I’m not even asking you to pay me for the prototypes or the materials used for it. Have you looked up the prices online? I’m profiting nothing.” You paused and looked her directly in the eye. “Look, I think this isn’t a good idea. “

“What are you saying? You don’t want to talk about it?” Amy asked, and you could hear the tone in her voice change slightly.

You sighed. “I’m saying I don’t think I can make anything for your wedding, or be your bridesmaid. I’ve said everything that needs to be said.”

“Y/N, you… What am I supposed to tell my family?”

You couldn’t hold back the chuckle that escaped your lips. You shouldn’t have expected anything else but the fact that she was more worried about having to explain what had happened to her family members who had always treated you as one of their own, spoke volumes.

“You can tell them what happened, Amy. Just remember that if anyone calls me, I’m telling the truth.”

Matt smiled and slung an arm around you, turning to lead you away before he paused.

He glanced back at Amy before he spoke, “She cared. She really cared and you threw it back in her face. She deserves someone who treats her as a friend.”

You tugged at Matt’s arm and Matt sighed before taking you away with him.

The journey home had been pretty silent and Matt only broke it as he closed the door behind the both of you and hung both your jackets by the door.

“You okay?”

You glanced up at him and nodded before you pulled back again and shrugged. “Kind of, you know? I’m upset but like it also feels lighter? If that makes sense.”

“It just has to make sense to you. The only thing important to me is how you are feeling right now.”

You stepped into Matt’s embrace and smiled against him. 

“With you? Matthew Casey, I’m on top of the freaking world.”

Matt smiled, leaning back enough to take a look at you before pressing his lips gently to yours in a deep kiss.

You were at Molly’s, nursing your third glass of wine for the night, hoping to forget about the terrible shift you just had.

It wasn’t supposed to be this way. It was supposed to be a quick in and out, but the universe had different plans. Thinking back, you start wondering what had gone wrong.

Truck and Ambo were called to a small fire at a local café. At first, it seemed like a minor incident, just burnt toast that had accidentally caught fire. What you hadn't realized, though, was that one of the stoves had been left on accidentally, causing gas to slowly leak out.

Upon arrival, your Lieutenant, Matt Casey, instructed Otis and you to escort everyone from the sitting area. Fortunately, there were only a few customers that day, making your job easier.

As you began ushering everyone out, a mother approached you and expressed concern that her six-year-old daughter was still inside. You asked Otis to stay with her before assuring her that you would locate her daughter.

Once the building was evacuated and Herrmann was preparing to hose down the kitchen, you radioed in about the missing girl and announced that you were going back inside to find her. Casey advised you to hurry up before the situation escalated making you nod and rush in.

Heading back in, you immediately began searching for the little girl. You called out to her, but there was no response. After checking the bathroom, you noticed her unconscious form lying under the sink. Your heart sank. You quickly checked her pulse and realized how faint it was. You removed your mask and placed it on her, hoping it would help her breathe. Once the mask was on, you swiftly picked her up and hurried towards the exit.

Passing by the kitchen, you didn't notice how the stove was on. You should have. You don't know how you didn't. It was your job to notice these things but you were in such a rush that it slipped your eye. The realization only dawned on you when you heard Herrmann yelling for everyone to exit the area because of leaking gas and by then, the explosion had already occurred.

The impact sent you stumbling backward, causing you to tumble to the ground with the girl in your arms. Casey’s voice crackled through the radio, but the ringing in your ears muffled the words. You couldn't seem to stop coughing and your head was throbbing making your vision start to blur. You felt yourself succumbing to the darkness, but you fought to regain your composure and struggled to stand up.

Once the initial shock had worn off, you quickly got up and made it to the exit, disregarding your injuries, only concerned about passing the girl off to Gabby and Shay. They tried their best, you know they did, but the girl was dead before you even got to them. The explosion had killed her. The explosion you should have seen coming.

That six-year-old girl passed away, and it was all your fault.

You were snapped out of your thoughts when you heard the sound of your name. It was Kelly, the Lieutenant of Rescue Squad 3, and one of your closest friends, whom you were currently sleeping with.

A few months ago, after a particularly difficult shift, Severide and you had accidentally ended up spending the night together. Since then, you two agreed to keep it casual— no strings attached, friends with benefits, if you will. Both of you promised to break it off if one of you started to catch feelings and that seemed reasonable to you.

“Rough day?” He asked taking a seat on the barstool beside you.

“Six-year-old kid died in my arms, so I'd say so.” You say looking down at your glass, twirling the liquid around mindlessly.

“Wanna talk about?”

“Nope, but I do want to get out of here. Your place? It’s closer.” You glanced at him, and he caught on to what you meant in an instant; you needed to let out your frustrations.

He nodded as you downed the rest of your wine and you two headed back to his apartment without any further questions.

You woke up the next day with an arm draped over your torso. You didn’t think much of it until you realized whose arm it was.

Shit.

You had never stayed over. You guys had never spent the night together to keep the feelings at bay. This was uncharted territory. So to say this was going to be awkward would be an understatement.

You attempted to quietly pull his arm away without waking him, but as soon as you made contact, you noticed him starting to stir.

“Good morning baby,” he voiced, groggily.

“Morning Kell,” You replied, blushing at the unexpected name.

“How are you feeling?” He asked, referencing the reason you were at the bar in the first place.

“Better.” You replied as you turned to face him. “Thank you.”

He didn't say anything, instead simply pulling you in for a quick kiss, letting you know he was there for you.

After pulling away, you decided it was time to get up. Popping the little bubblle you were in and ending the moment you shared.

“I'm gonna get dressed and head out, I didn't mean to stay over- just got carried away. I know we don't do that so I'll leave, sorry.”

“Y/N wait up-” He says, catching your attention.

“Yeah?” You turn around to look at him.

“I don't mind that you stayed, I know you had a tough day yesterday so it's fine. Make yourself at home sweetheart.”

The nickname caught you off guard once more. It wasn't unusual for him to shower you with praise and call you these names during sex. But afterwards? He'd never spoken to you that way and the sudden change was putting your heart in a whirl.

You sighed trying to regain your composure. “Yep, thanks. I'll uhh… I’ll see you at shift.” You brushed him off, smiling.

Since that day, the dynamic between you two has shifted noticeably. Others at the firehouse have started to take note of it as well. He's become more attentive. Making sure he has a meal saved for you when you're too busy to eat, accompanying you home from Molly's when you've had a few drinks, and checking in on you after difficult calls.

It wasn't just him, though. You’ve been overly caring with him too, more than a friend should be. When he discovered he had a half-sister, you stood by him. You supported him in reaching out to her. And when she was going through a rough patch after her kidnapping? You were the one on the phone talking her down when she made the decision to move to Colorado.

After all your help, his mother even invited you to her house as a token of gratitude. You never intended to become so involved with him and his family, it changed how you saw him.

You heard the rumors, you knew he was a player— a womanizer who didn't care about anything except his pleasure. But witnessing his interactions with his family alongside the kindness he's been treating you with recently? It was coming to be harder and harder to view him as selfish and uncaring.

The line between friends and lovers was becoming increasingly blurry. Yet you were still trying your hardest to avoid the development of feelings because you knew once you crossed that threshold, there was no going back.

You were walking towards the kitchen when you caught Casey and Severide engaging in conversation by the coffee pot.

You didn't mean to eavesdrop but hearing your name leave Matt’s lips made you stop dead in your tracks.

“What's going on between you and her?” He asked.

“Nothing. It’s all casual. She's nothing more than a friend, Case. We're not together.” Kelly replied, a little too firmly.

Ouch.

You knew nothing was going on between the two of you but hearing that coming from him? It hurt more than you'd like to admit.

You imagined sharing an apartment, perhaps a year or so from now and spending the coming years wrapped in each other's arms, building a family. You chuckled to yourself at the fact that you even thought that was a possibility at some point. Realizing now how naive it was to believe he would ever view you as anything more than a fuckbuddy. Oh, how you loved being stupid.

You spent the rest of the shift avoiding him. It wasn't fair to him; after all, he didn't know you had overheard. Your feelings were your problem, and it wasn't right to act as though he were responsible. Yet, facing him felt impossible without making a fool of yourself.

You found yourself at Molly’s again. Downing shot after shot. You knew you were way past your limit but the lack of Kelly Severide-related thoughts in your brain was encouraging you to continue.

It had gotten to the point where you noticed Herrmann giving you shots of water instead but you were too far gone to care.

You were about to request another real shot when you felt a presence next to you. You turned your head to the side and saw the one person you were trying to forget about.

Lieutenant Kelly Severide.

“You've been avoiding me.” He said, less of a question and more of a statement, keeping his eyes on you.

You hated how small he made you feel, like he could read you in just one glance. His intense gaze made you look away before trying to find Herrmann. “I have not. Now excuse me, I was about to order another drink.”

“You don't need another one.” He said, grabbing your shoulders and turning you back around to face him.

“What are you? My boyfriend? We’re just friends Severide, you don't get to make that decision for me.” You wouldn't have usually been that snarky but the alcohol in your system was giving you courage you didn't know you had.

He was taken aback by your response, you were never like this with him. It was worrying him.

He tried to help you stand up, “Y/N c’mon let's get you home.”

You reluctantly agreed. You knew you were going to regret this in the morning but at the moment, you didn't care. He started walking you towards the exit when you pulled yourself away from him and spoke up, “I don't need a babysitter. I can walk by myself.”

“If you actually think I'm letting you walk home, drunk and alone at this time of night, then you're crazy.” He replied casually while walking beside you.

You stopped abruptly and sighed, looking down. “Why do you do that?”

“Do what?” He questioned, placing his finger under your chin bringing your face up to meet his.

“Why do you act like you care?” You clarified, holding his stare, pretending his touch wasn't erupting fireworks in your stomach.

“I do care! I care more about you than you realize Y/N.” He said a bit too loudly, raising his hands in exaggeration.

“You're not supposed to!” You shouted back.

“Why not? Is it such a crime to care about my friend?” He replied, exasperated and upset.

There it was. The dreaded ‘friend.’ You knew it was coming. So why did it still shock you?

“I- I can't do this Kelly- I'll just call a cab to take me home, you don't need to walk me. Forget anything happened.” You said turning around, ignoring his objections, calling your name.

You spent your days off moping around. Kelly had called you multiple times and left countless messages, but you couldn't bring yourself to respond. You knew you were being childish, but it didn't matter. The thought of going back to work and having to face him filled you with dread but that was a problem for later. Right now, you have errands to run.

While you were getting dressed, you absentmindedly opened the drawer meant for Kelly. You couldn't avoid him, he seemed to be everywhere you looked. Your phone, your workplace, and now, your dresser.

You sighed. The fact that you two had separate drawers designated for one another at each other's homes, slipping your mind completely. Is that something friends with benefits did? Did they keep clothes at the other’s place to ‘make it easier for them to get dressed?’

Your thoughts were cut short when you heard a knock at your door. You weren't expecting anyone but opened the door regardless not guessing who you’d see on the other side.

You found yourself face-to-face with none other than the man who had been plaguing your thoughts nonstop. However, after avoiding him for so long, you didn't know what to say or how to act. You felt like you’d never been in such close proximity with him before, it was suffocating. So you simply stood there until he eventually spoke.

“We need to talk.” He stated simply.

“What's there to talk about?” You asked, avoiding his eyes.

“This. Us.” He said, motioning between the two of you.

You finally took a good look at him, you noticed the heavy bags under his eyes and the weary slump of his shoulders. It was clear that he was utterly exhausted, as if he hadn't slept at all in the last few days. And the simple thought of the reason for his exhaustion being you, made you feel terrible.

“Severide-” You couldn’t let this drag on for any longer without hating yourself, so you took a deep breath and continued, “I think we should end this arrangement that we have.”

“What?” He furrowed his brows.

“We agreed that once one of us starts catching feelings, we'd end it. So let's end it before it gets messy and hurts either of us more than it should.” You tried closing the door once you were done speaking but he quickly squeezed himself in, preventing your attempts at pushing him away.

“What are you doing?” You asked following him into your apartment.

“That's not fair!” He exclaims, “You don't get to ignore me for days and then just end our relationship and shut me out.”

“This was hardly a relationship.” You scoff, “But, what did you want me to do Kelly!?” You matched his volume, watching as he paced in the middle of your living room.

“I don't know, maybe talk to me about how you're feeling!” He said, tone dripping with sarcasm while glaring at you. If looks could kill, you'd be six feet under right about now.

“Oh, that's really mature coming from you! Mr. Expert at communication.” You replied with just as much pettiness as you could muster, stepping closer to him to prove a point.

He stood silent for a moment before taking a deep breath and approaching you, “Maybe you're right, maybe we do need to end this thing we have. I just thought we cared about us enough to at least talk it out.”

The two of you now stood face to face, your breaths labored and eyes locked in an unbreakable gaze. Silence enveloped the space between you, the tension so thick that it felt tangible like it could be sliced through with a knife.

“I’m sorry.” You said quietly. “I shouldn't have ignored you and I also shouldn't have just sprung that on you.”

Once you noticed he was letting you continue, you went on, “I just realized that I couldn't be as ‘casual’ about our relationship as you are anymore. I tried to hold my tongue and ignore the feelings I have for you, but it was getting harder Kelly. Nothing about our deal has been casual for weeks now and it was starting to affect me.” You finally let out.

He took in your words, shaking his head. “It hasn't been casual for me either Y/N. I love you, and have for a very long time.”

The force of his words hit you like a physical blow. Love? How did he claim to love you when he had not only never hinted at such feelings before but also dismissed Casey when he asked about it? You were confused and it was evident on your face with the way you looked at him, shell-shocked.

“You love me? But you told Casey that there was nothing going on between us and-”

You were quickly cut off by his hands on your face, pulling you in. The intensity of his lips against yours short-circuited your entire being. It took a moment for your brain to register what was happening, but soon you found yourself reciprocating his kiss.

While you and he had shared kisses in the past, this one was different. It wasn't hurried like your usual kisses but instead filled with a deep sense of passion, tender and slow, and brimming with love and adoration for one another.

He placed his hands gently on your waist, drawing you closer, deepening the kiss. You raised your arms, threading your fingers through his hair, feeling the slight tug as you did. It was as if your lips were pulled together by an irresistible force, making it difficult to part.

You wanted time to freeze in that beautiful moment so you could stay in it forever. You wished to remain embraced by him indefinitely. His touch was tender and affectionate, brimming with care. It felt as though both of you had shed all your worries and were completely immersed in the love surrounding you.

You tentatively ended the kiss and gazed into his eyes, which stemmed a love you had never felt from him before. For the first time, they didn't overwhelm you or make you feel small; instead, they enveloped you in a sense of comfort. And in that fleeting beat, his eyes spoke volumes even when his words remained silent.

“I love you too.” You said, sharing his sentiment, causing a grin to emit on both of your faces.

You felt like a teenager who was experiencing love for the first ever time; and you wouldn't want it any other way.

Kelly 😏😏

When you started dating Kelly you almost expected him to bolt when he found out you had kids. Instead he did the opposite. The man took to the role like a fish to water. Your kids adored him and he adored them. When your teenager let it slip that one of the teachers at her school was talking to the girls inappropriately you wanted to handle it. Unfortunately Kelly overheard.

“Matt, I’ve got a stop to make” Kelly told Matt and as soon as he filled him in on why Matt was more than glad to ride along with him. Your daughter was in the cafeteria when she spotted Kelly and her eyes got big “Uh oh” she muttered and her friends twisted around to follow her line of sight, all of them spotting Kelly and Matt. “Isn’t that your mom’s boyfriend?” Kiara nodded “Yup”

She watched as Kelly went up to the teacher in question “Excuse me. Are you Mr Franklin?” Mr Franklin turned around and nodded “Yes, and you are?” Kelly pointed back to Kiara “Someone who cares about her. Can we talk?” “I don’t think now’s a good time” Kelly smiled “I didn’t mean to sound like I was giving you an option”

He put his arm around Mr Franklin’s shoulder and walked him out of the cafeteria with Matt following the two of them. Kiara watched with wide eyes. A few minutes later Mr Franklin walked back in, pale as a ghost and Kelly walked in behind him. Kelly walked over to her “Come on sweetheart, you’re coming with me” 

She gathered her things and followed him, watching Mr Franklin “What did you say to him Kelly?” Kelly shrugged “Just a warning that if wants to say certain things to teenage girls he better make certain as to who those teenage girls have backing them and what those people are willing to do” 

A few days later Mr Franklin quit and it was pretty much made known not only for Kiara but for your other two kids that if you messed with them the entirety of fifty one was coming too. You’d never found yourself even considering proposing to a man but for Kelly Severide? You might just be thinking about it.

Can you write a Matt Casey x female reader story?

Matt Casey is married to his dead best friend Andy Dardens little sister. Y/n is the PIC on ambo 61 and her partner on ambo is Gabby Dawson.

Y/n and Matt are taking care of Ben and Griffin since Heather is in prison. Everything is good between Matt and y/n, they are doing the best they can with taking care of two boys.

Y/n finds out that she is pregnant and one evening when the boys are asleep y/n tells Matt that she’s pregnant.

A little smut if you can get that in to the story, and of course if you feel comfortable with it.

Aunt & Uncle to Mom & Dad

Here's my first Matt request! Comments really appreciated ❤️

“Thanks Gabby. I’ll ride back to the house with Matt.” I called over my shoulder getting out of the passenger seat of our ambulance truck. She waved bye to me as I quickly went inside the school. Moving down the hallway I found my brother's older son Griffin sitting outside the principal's office. Putting a hand on my hip I shook my head at him asking. “Is Casey already talking with him?”

“Yes, aunt Y/n.” Griffin nodded before I opened the door and shut it behind me seeing Matt was already talking with their principal and hadn’t noticed I was there just yet.

“Believe me, Griffin and I are gonna have a long talk the minute I get off shift. This won’t happen again.”

The principal sighed heavily sitting at his desk. “I have to say, Matt. This whole childcare situation doesn’t exactly instill me with confidence.”

“We’re making the best of it.” Matt told the principal simply.

“And who exactly is we? If you don’t mind me asking?”

Waving to the pair I finally introduced my presence in the office, walking up to the principal I shook his hand sitting down beside my boyfriend. “I guess it’s time I introduce myself, I’m Y/n, Y/n Darden. Ben and Griffin are my nephews. My brother Andy was also best friends with Matt here, that’s why we were both asked to take care of them by their mother Heather.”

“And how exactly do you know Mr. Casey?” The principal shifted his gaze between the two of us.

Gently looping my fingers through Matt’s I responded knowing this all is a bit much, especially considering we aren’t even married yet. “He’s my boyfriend. And as I said a minute ago my sister in law Heather asked both of us to watch out for them until she gets out.”

“Well it’s good to know that neither of you is having to raise these two young boys by yourself.” The principal nodded and thankfully he let us take the boys home after that. Matt and I had called into our captain and let him know we weren’t going to be able to finish out our shifts tonight but that we would them up another time.

Once we all had finished eating dinner I sent the boys off to get ready for bed. Matt was cleaning up the kitchen while I went to check on the boys, finding that Ben was asleep but Griffin was still awake so I whispered into the room getting his attention. “Can’t sleep, buddy?”

“I miss my parents.” He sniffed beginning to let some tears fall down his face.

Sitting down on the edge of the bed I gently ran a hand down his back knowing it always made me feel better when my brother would do it when I was upset. “Yeah. I miss your father too, Griff. I’m going to tell you something that most people say but when I say it you should know that it’s the truth.”

“What’s that, Aunt Y/n?” Griffin asked me, looking up at me.

Tracing patterns on his back I sniffed back some tears that were appearing in the corner of my eyes when I began explaining to him. “The same pain that you feel about missing your father I feel it too. I lost my brother. A lot of people will try to understand or claim that they know what you’re going through and some do and then some don’t. But I can tell you right for certain that I understand 100% what you are feeling when it comes to missing your father.”

“Thank you, Y/n.” Griffin spun around and flung his arms around my neck, crying some happy tears.

Wrapping my arms around his waist I kissed his forehead gently holding him tightly against my body until I smelled the fabric of his shirt suddenly feeling sick to my stomach for some reason. “You’re welcome - urgh!” Separating myself from the kid I dropped down on my knees grabbing his trash can in the corner and puking the dinner that I had eaten.

Griffin jumped down from his bed running over to me with concern. “Aunt Y/n, are you okay?”

“Uh - I guess dinner isn’t setting right for me.” Wiping my hand across my mouth I cleared my throat, sending my nephew a weak smile. “I’m alright. You don’t need to worry. Now get some sleep, you’ve got school tomorrow.”

He nodded going back over to his bed and climbed underneath the covers. “Goodnight Aunt Y/n.”

Leaving the two boys' bedrooms I entered my shared bedroom with Matt going directly to the bathroom. Rummaging around in the cabinet until I found a box of pregnancy tests I had recently bought at the store. Locking the door I sat on the toilet peeing on the stick and waited for the results, hearing a knock on the other side followed by my boyfriend’s voice. “Y/n, Y/n, are you okay. Griffin told me you got sick a few minutes ago in his room.”

“Give me a minute, Matt.” I called back to him, reading the time on my phone and seeing the test should be ready. Slowly opening the bathroom door I found my boyfriend leaning in the doorway until he saw me holding a pregnancy test in my hands. “There’s something I gotta tell you. I know that you’ve always talked about having kids and I know we haven’t really been trying but it’s -“

“You’re pregnant.” A huge grin crossed Matt’s face, stopping me from finishing my sentence, scooping me up into his arms and connecting our lips in a passionate and slow kiss.

Matt signaled me to jump and I wrapped my arms around his waist still holding the test in one hand. He walked me over to the bed and I tossed the test onto the bedside table. We fell down onto the mattress finally breaking the kissing to catch our breath. “So you’re happy, Mathew?” I giggled watching him begin to remove his shirt and I shrugged my own over my head throwing it somewhere onto the floor.

“Hell yeah I’m happy.” He chuckled, nuzzling his nose with mine, helping me remove my clothes and I did the same thing to him until he was hovering over me completely naked. He scanned my face more so asking about me having his kid then having sex. “Are you okay with all this? I know your nephews are enough of a handle right now.”

“We’re first responders, Matt. Having a baby has to be easier than the things we face on a daily basis.” Laughing playfully I wrapped my arms around his neck drawing him in for a kiss. He slowly slid his body into mine and the maitress began squeaking underneath our movements.

Matt bent his head down leaving kisses down my neck until he reached the crook of my neck, I moaned instantly when he kept kissing that particular spot. “I love you, Y/n - you’re gonna be a mama.”

Grabbing the sides of his face I pressed his forehead against my own. “Love you too. You’re going to be a daddy, Matt Casey.”

Matt smashed his lips upon mine with my back being pressed against the mattress some more. “Our next goal is finally getting your name changed to Mrs. Y/n Casey.” I threaded my fingers into his already messy hair, our bodies molded together letting us get lost. Our family of four would soon become a family of five and we couldn’t be happier.

Stuck With Me

After a car accident leaves Y/N in critical condition, Casey anxiously waits by her side as she fights for her life, grappling with his own fears and the weight of everything they've both been through.

Y/N had been on her way to start her shift at Med when it happened. One second, she was slowing for the intersection; the next, the world exploded in shattering glass and screeching metal. The impact sent her car spinning, slamming into a streetlight. Then, nothingness.

Brett and Violet had just finished a call when the dispatch came through—major MVC, driver unconscious, possible entrapment. Their stomachs dropped when they heard the location. They instantly recognized the location, as it was on the route you typically took to get to your shifts at Med.

They arrived to find Y/N trapped, barely conscious, blood pooling from a head wound. She was breathing—but barely, and it was visibly laboured. Violet gets into the passenger seat and starts IV and gets a C-Collar on her.  Squad 3 pried the door open, and gently moved her to the gurney. Just as she was settled on the gurney, the monitors shrieked in warning as she flatlined. 

“No pulse!” Violet shouted. “Starting compressions!” She jumps on and straddles the gurney as Brett and Severide load it in. 

Casey arrived just in time to see them loading Y/N into the rig, Brett delivering a shock with the defibrillator, as Violet sat back on the bench and spoke into her radio. His stomach turned as he saw your body jolt. Matt tried to jump into the back of the ambulance, but Severide held him back before slamming the doors shut, as Cruz got into the cab and gunned it to Med. 

En route to Med, Violet is doing compressions, while Brett gets you intubated since you were no longer protecting your airway. 

Once they arrive to Med, it is a host of organized chaos

"Female, late 20s, T-boned at high speed—found unresponsive at the scene, GCS 3. Sustained significant chest trauma with suspected cardiac contusion or tension pneumo. Lost pulses as we left the scene—three rounds of epi given, three shocks delivered. Intubated en route, no spontaneous respirations. Six-minute downtime."

“Going to Baghdad” Maggie called out as they rushed past. 

As soon as they entered, the trauma room was chaos—beeping monitors, the hurried shuffle of feet, the thud of chest compressions. The team had been working for what felt like an eternity, but nothing was giving. Will, Ethan, and Connor moved in sync, pushing meds, shocking Y/N again and again, trying to pull her back from the brink.

“Pulse?” Connor asked, voice strained, eyes fixed on the monitor.

“Nothing,” Will answered, his voice low but firm.

Connor turns to the defibrillator and starts charging it again. 

"Charged to 360! Clear!" Connor shouted, his voice cutting through the noise of the trauma room.

The room fell silent for a moment as Y/N’s body jolted once more, the shock coursing through her.

Seconds ticked by. All three doctors were watching the monitors, when suddenly, the beeping of a faint pulse began to return. Connor’s heart hammered in his chest.

“She's back,” Ethan breathed, exhaling a breath he hadn’t realized he’d been holding.

Connor quickly turned his attention back to Y/N, watching her intently. 

“We need to get her to the OR,” he said, taking charge, his voice steady and commanding. “I’m not wasting time. Let's move.”

He looked over to Will and Ethan. “You ready?”

Will nodded, already prepping the IV fluids. “Let’s go.”

Severide appeared in the doorway, his face tense with worry, but relief in his eyes. “Is she stable enough to move?”

“For now,” Connor replied, turning to the gurney, adjusting Y/N’s head gently, making sure your airway was secure. “But we’re pushing it. We can’t wait much longer.”

The team was quick to wheel Y/N out of the trauma room, and Connor took point, pushing the gurney with a sense of urgency. He never took his eyes off of her, watching the mechanical rise and fall of her chest from the ventilator and the pulse on the monitor.

“Stay with me, Y/N,” he whispered to himself, though he knew you couldn’t hear him. His breath caught as they reached the hallway, the tension thick in the air.

The OR doors loomed ahead, and the weight of the moment hit him like a ton of bricks. He had no idea what would happen when they got you inside—but he knew one thing for sure: He wasn’t letting you go without a fight.

The team rushed you into the OR, and Connor didn’t hesitate. He followed immediately, calling orders as they moved into the sterile environment.

“Let’s get everything prepped. I’m not losing her,” Connor said, his voice sharp and filled with determination. “She’s strong. We’ve got this.”

In the hall

Casey stood there, numb, watching the love of his life disappear behind the operating room doors.

And then, as they wheeled her past—his vision swam. The world tilted.

Someone called his name. Hands grabbed at him.

Then—nothing.

“Casey!” Severide barely caught him before he hit the floor. He was completely out—limp in Severide’s arms.

Brett rushed for help. Choi arrived within seconds, immediately checking Casey’s vitals. “Pulse is weak—thready. BP’s tanking.”

“Matt, come on,” Severide muttered, shaking him, but he didn’t stir.

Choi pressed his knuckles hard against Casey’s sternum, rubbing roughly.

Nothing.

Another rub.

Casey suddenly gasped, jerking violently. His eyes flew open, wild and unfocused.

Then he fought.

Casey came back swinging. Hands on his arms, voices all around him, his body on fire. He felt trapped—pinned.

“No—get off me!” He thrashed, panic clawing at his chest.

“Hold him down!” Choi barked. “If he doesn’t stop, he’s gonna crash again!”

“Casey, stop!” Severide’s voice cut through the chaos. “You’re safe. You passed out.”

But Casey wasn’t listening. His body was still in fight mode, reacting purely on adrenaline. Choi didn’t hesitate.

“Two milligrams IM Ativan—now.”

A sharp prick in his shoulder. Seconds later, warmth spread through his veins, dragging him under.

The next time he woke, he was in an ER bay, IV now in his arm, nasal cannula delivering oxygen. His head throbbed. His limbs felt like lead.

“Easy, man.” Severide was beside him.

Casey blinked, sluggish. “What…”

“You passed out. Went completely unresponsive. Scared the hell out of all of us.”

Flashes came back—Y/N, the OR, the panic, the blackout.

Casey swallowed hard, noticing the IV in his arm. He reached up to yank the nasal cannula off—

“Don’t even think about it,” Severide warned, standing to place a heavy hand on his best friend’s shoulder.

Casey scowled but relented. “Where’s Y/N?”

Severide hesitated. “Will should be out soon.”

Minutes stretched painfully before Will appeared.

“She made it,” Will said. “Surgery went well. She’s stable.”

Relief hit Casey so hard he nearly choked on it.

Severide wheeled Casey up to her room, IV still hooked up. When they entered, Y/N was just starting to stir. Her eyes fluttered open, hazy with sedation. Her gaze landed on Casey.

She blinked, confusion flickering across her face. “Matt?” Her voice was hoarse from the tube.

“Hey,” Casey rasped, moving closer. “Yeah, I’m here.”

Her eyes drifted to the wheelchair, to the IV still in his arm. Her brows furrowed. “What… what happened?”

Casey hesitated, but Severide filled in the blanks. “Idiot over here passed out in the waiting room when they took you back.”

Y/N’s lips parted in faint surprise. “You—what?”

Casey exhaled. “Guess I didn’t handle it well.”

She gave a soft, tired smile. “You’re stuck with me, Casey.”

His throat tightened as tears started rolling down his face. “Yeah,” he murmured, taking her hand gently. “I wouldn’t want to be anywhere else.”

The first few days of your recovery were rough. The pain was unbearable at times, but the exhaustion was worse. Physical therapy was grueling. But Casey never left your side.

Some days, she made progress—sitting up, taking a few steps.

Other days, the setbacks hit hard—pain flaring, dizziness keeping you in bed. Frustration weighed on you, but Casey was always there, steady as ever.

“You got this,” he’d whisper, pressing a kiss to her forehead.

One night, you broke down, tears slipping free. “What if I don’t get back to how I was?”

Casey cupped your face. “You're not alone. We haven’t crossed that bridge yet, but if we do, then we figure it out together.”

Y/N exhaled shakily. Then, she leaned into him.

Because through it all—through the pain, the fear, the uncertainty—one thing remained true.

She wasn’t doing this alone.

And neither was he.

Where you and Shay go from girlfriend's to wives

“Kelly Severide, stop laughing at me.” Shay said in frustration. “Why? It’s funny that you have something bad to say about every beautiful ring you see.” Her best friend had been with her in the jewellery store for the past hour, not to mention that it was the fourth jewellery store they had visited in the past week. 

“The ring has to be perfect, Kelly.” He shook his head, “I know, but at this pace there aren’t going to be any rings left in the world. That girl is head over heels for you, and will say yes no matter what ring you pick. “Still I want it to be perfect.” 

They kept looking around at the ring collection this store had until Shay’s eyes fell on the one. “Oh my god, that’s it. That is the ring!” Kelly celebrated quietly behind Shay’s back. He loved his best friend dearly, but was also glad that he would finally be spending his days off somewhere other than in a jewellery store.

For Shay it had been easy to keep her thoughts of wanting to ask for your hand in marriage, but now that she had something physical to do it with, she was anxious you would find out. She had given Kelly the ring for safekeeping, but still she knew that she wouldn’t be able to keep the plan a secret for much longer. So, she changed her original plan a little bit, and decided she was going to ask you on your next date night.

Since you both worked 24 hour shifts at the firehouse, you made sure that you made time for each other on your hours off. One of the things you did to reassure you would have some time set aside was a set date night. It really didn’t matter what you did, the only thing that mattered is that you did it together. 

Today’s date night, you went to the Field Museum of Natural History. They had a dinosaur section, which is exactly why Shay wanted to bring you here. You loved dinosaurs and learning more about them. You thought the museum was amazing, and were running around showing her things like an excited little kid.

When you got back home, you were still talking about the dinosaurs. So much so that you didn’t realise the set up of your living room. Shay looked around, very happy with how her idea had played out. She had asked Kelly and Dawson to set up the “Will you marry me?” sign surrounded by a rose petal heart. It looked absolutely perfect, now you just had to look around. 

The moment that you did, time stood still. You looked at the setup in front of you with your jaw dropped, and eyes widened in surprise. When you turn to look at your girlfriend, she is down on one knee and holds out an open ring box towards you. “Yes, yes, yes!” You say with tears in your eyes. 

“You're not even going to let me ask the question?” She giggles with tears in her own eyes from your excitement. “Oops?” You laugh back. “Please ask me, darling.” 

With a big smile on her face, Shay holds your hand. “You are my best friend, and I want to spend the rest of my life by your side. Y/n Y/l/n, will you marry me?” 

You're now both full on crying, but in the best way. “Yes, I will definitely marry you!” You fall into her arms and sob happy tears into each other's shoulders. 

The rest of the evening was spent in the comfort of your home and each other's arms. It wasn't until the next day that you told people about your engagement. Shay sent Severide a picture with the text “She said yes!” He congratulated the both of you and invited you for a drink at Molly's.

Of course, you should have expected the whole team to be waiting for you inside of Molly’s as you arrived. All of them yelling out “Surprise!” When you walked through the door. It was nice celebrating this step in your relationship with the people closest to you, the people that had become your family over the years.

The next day where the team was back at work, the room buzzed with energy. Everyone was excited about the engagement, and was asking all kinds of questions about your plans for the wedding. Above all else, they were thrilled that the couple they had seen grow over the years, was taking the next step together.

Your day started off calm, but as soon as that first bell rang, you knew it wouldn’t be stopping any time soon. As you expected, the calls began to pile up, and the intensity grew. A handful of car accidents, a heart attack victim, and a kitchen fire kept you busy in just the morning.

There was just enough time to have some lunch, before the bells rang again. All units were called to respond to the scene, so you knew this was going to be a serious one. 

A multi-story building had caught fire, and people were still trapped inside. You rushed into truck 81 and your team raced to the scene. When you got there you realised just how far gone the building was. Flames were shooting out the windows, and thick dark clouds of smoke hung around the tall frame of the building. 

Without hesitation, you all sprang into action. “Y/l/n, you’re going up with me. The rest help Squad.” You put on your mask and ran inside, following close behind Casey. When you got up to the fire floor, there was no time for second-guessing, you had to go before the building would collapse. 

The heat and the thick smoke combined, made it hard to see anything at all. Yet you kept yelling out, until finally you heard voices respond. A family of four was hiding in the bathroom, as most of the room was engulfed in flames. 

You and Casey worked together to get the trapped family into the hall. You stood in the middle of the room, helping them over the flames, while Casey got them into the hallway. The moment that the family was out in the hallway, the ceiling about you gave way. 

One of the beams came crashing down, and pinned you to the floor. “Go, get downstairs!” Casey shouted to the family. The safest for them was to head down and meet another firefighter there, he didn’t want more of the ceiling to collapse while the family was still there.

“Mayday mayday, firefighter down on the sixth floor.” He radio’s in while he makes his way to you. Seconds after Shay’s voice is heard over the radio. “Casey, is y/n okay?” He doesn’t answer, as he doesn’t know the answer himself yet. 

“Casey, come in.” Boden requested as the line was still quiet from your end. “Getting to her now. The ceiling collapsed and she’s trapped under a beam. She’s conscious, but I need help getting it off of her.”

You were conscious and talking to Casey while he was trying to pull the beam off himself, without any luck. Luckily more people arrived to aid him, very quickly. With many hands, cribbing, and the right tools, they were able to get you out from underneath the weight of the beam quickly. 

When you got outside, one arm over Casey’s shoulders and the other over Severides, you finally felt like you could breathe again. Shay ran into your arms. “Are you okay? Let me check you out, please, I need to make sure that you’re okay.” You lift your arms from the boys and hold onto your fianceé. “I’m okay, just going to be really sore tomorrow.”

“I thought I lost you.” You shake your head. “You’re not getting rid of me that easily.” You joke, but you were well aware of how the situation could have ended. “Life is too short. I don’t want to waste any time.” Shay was quick to chime in, “You don’t have to convince me, let’s get married as fast as we can.”

After a long and exhausting shift, the team got together for a small firehouse wedding. It was just quickly thrown together, but you had all you needed. Your bride and your family surrounding you. 

Severide walked Shay down the makeshift aisle, while you were standing in the doors of the apparatus floor with Casey by your side. He was like a brother to you, so there was not even a question on your mind when Shay asked you who you would want to walk you down the aisle. “Are you ready?” He says as he watches your eyes meet Shay’s. “I’ve never been more ready for something in my life.”

You met Shay between Truck 81 and Ambulance 61, a small touch to give even more meaning to this day. Boden stood between you, who better to officiate your wedding than the man that had been like a father figure to the both of you.

The ceremony, while simple, was perfect. It was a day neither one of you would ever forget. After you had said your I do’s and sealed your marriage with a kiss, you carried Shay inside bridal style. 

While the day may be over, your shift was not. But for now the team would rest, and hope to be recharged enough when the next bell rang. For you the day was perfect, just because you had Shay by your side for the rest of your life.

Masterlist | Matt Masterlist

You’d never have expected Matt to have such a dirty mind, let alone a dirty mouth. But when you riled him up. Whether it be by flirting with him in the common room or purposely pushing yourself up against him in the locker room, he could get to be quite the filthy talker.

And that was evidently proven when he dragged you into his office after having had enough of your teasing for one day, deciding it was high time he did some of his own just to see how you liked it. He drew the blinds, inciting heat deep in your core as he only ever did that when he intended for things to get steamy.

Pulling you close to him, Matt fell back into his chair, which rolled slightly across the floor and banged into the wall. You were quick to straddle his lap, wrapping your arms around his neck as you kissed him deeply. Passionately. Enough that he almost forgot what he brought you in here for.

“When we get home…” Matt whispered, digging his fingers deep into the fleshed of your clothed ass as you ground your hips down against him, making him twitch beneath his pants and almost lose his train of thought.

Again.

His eyelids fluttered, breath hitching in his throat as he tightened his hold on you, stopping you from doing it a second time otherwise he’d never be able to actually get his teasing words out.

“Fuck…” Matt groaned lightly, his hold not quite tight enough as you managed to get one more grind of your hips in before he pulled you closer to his chest, feeling the soft mounds of your breasts pressed against him. “When we get home, I’m gonna tear your clothes off and pound your pussy so hard you can’t see straight.”

“Why wait? Why not do it now?” You replied breathlessly. Like a dog in heat. Practically begging him to pin you down and fuck you as the mere heat that had formed between your legs at his words was unlike anything you’d ever felt before.

You didn’t know if you’d have been able to wait so long to feel him absolutely destroy you, and perhaps you shouldn’t have been so intent on teasing him as you could tell he was trying to play a dirty game. Luckily for you though, you were great at games and oftentimes you got exactly what you wanted.

“You want me to fuck you now?” Matt questioned, grazing his knuckles down your chest and feeling the hardness of your nipples poke through your bra. He carried on, every inch closer he got to your lower half making your legs tighten around his. “Want me to pin you down on my bunk and fuck that tight little pussy of yours?”

“I want you to fuck me, baby.” You whispered, the desperation slipping shamelessly through your lips.

Especially when his hand delved beneath the dark material of your pants, working their way under the already soaked material of your panties. He began to drag his fingers painfully slowly across you, feeling just how wet you were for him and finding pleasure in the soft whine you let out from his touch.

“Fuck, Matt…” You couldn’t help the gentle moan from escaping your throat at the way he teased you. Pushing his fingers into your pussy barely a centimetre before pulling back out, in the exact way he knew drove you crazy and left you craving more. “God, please fuck me… Let me feel that huge cock inside me.”

You knew he couldn’t resist it when you talked dirty. Especially in that tone. That heated, whining, desperation filled tone that could have him leaking under his boxers the second it left those soft lips of yours. The ones that were currently exploring his neck, your hot breath puffing out over his skin as he continued to tease you, rubbing his thumb over your clit just lightly enough that it couldn't give you exactly what you wanted just yet.

Which is what Matt wanted. He wanted you like this. Desperate. Craving more and the second a throaty gasp left your lips when he applied just a touch more pressure, he was on his feet and tossing you down onto his bunk before you could comprehend what was happening.

“Forget waiting.” Matt practically growled, pupils blown wide with lust as he freed you of your pants. “I’m gonna pound that sweet pussy now.”

You could tell by his face that he was serious. That you were in for a rough time and it only turned you on more. You watched as he grabbed your panties, almost ripping them off you in attempts to get you out of them. He bunched them up, shoving them into your mouth in best efforts to keep you somewhat quiet as he didn’t think the firehouse would appreciate hearing him destroy you.

You spread your legs as wide as you could, riddled with hunger as you did nothing but watch as he pulled his cock from his pants. It sprang up almost instantly, rock hard already and dripping from the tip. He gave it a few quick pumps, biting back a moan as he stared directly between your legs.

“You ready, baby?” He asked, stroking his length a few more times before positioning himself on top of you. You nodded, your hand running down his still clothed chest, fingers wrapping around his cock as you gave it a gentle tug towards you, a deep, rattling moan escaping his lips as you did.

The muffled cry that erupted through the panties in your mouth as he bottomed out in one quick motion was enough to get Matt going completely. The speed at which he moved was unlike anything you’d ever felt before, his hips slamming against your thighs as he made good on his word of pounding your pussy until you couldn’t see straight.

You already couldn't see straight and it hadn’t even been a minute yet. But you loved every damn second of it. The slight hint of pain only added to that intense pleasure coursing through your veins. Your lower abdomen was on fire, tightening faster than ever with each thrust of his cock, reaching deeper inside you than it ever had before and sending you to heights you never thought you’d reach.

You made a mental note to rile him up like this more often as when your orgasm hit, it was as though you’d ascended to heaven. Like you were floating from your body and for a good thirty seconds, you saw nothing but white as Matt carried you through it, prolonging it to the point where you had to tell him to stop before you became too overstimulated that it started to hurt.

Luckily though, it only took Matt two more deep thrusts to reach his own end, collapsing on top of you as though he’d just ran a marathon and then fought a blazing fire. You were both sweating, unable to breathe let alone speak but that didn’t stop him from kissing you, pushing your hair back from your face as his lips worked lightly, gently, against yours before he whispered, smugly.

“Same time next shift?”

CHICAGO FIRE (2012 -)

– 08x16, The Tendency of a Drowning Victim

[sevasey51]

Steady Ground

Pairing; Matt Casey & Kelly Severide x Platonic! Reader.

Summary; reader comes to the firehouse for a night of uninterrupted games with the guys when a seizure hits.

Warnings; seizure mention, just pure fluff

The sun was setting over Chicago, painting the sky in warm hues as you walked toward the firehouse. You had planned to visit your friends, Matt and Kelly, after a long week. As you approached, a sense of comfort washed over you, knowing you could count on them for support and laughter.

Inside the firehouse, the atmosphere was lively. Laughter echoed through the common room as the crew shared stories. You stepped in, greeted by Matt’s warm smile. “Hey! Glad you made it.”

“Wouldn’t miss it,” you replied, feeling at ease.

As the evening progressed, you found yourself sitting with Matt and Kelly, discussing everything from work to life. But amidst the laughter, a familiar sensation crept over you—an aura that signaled a seizure was coming. You tried to brush it off, hoping it would pass.

“Are you okay?” Matt asked, noticing your sudden stillness.

“Yeah, just a little dizzy,” you lied, forcing a smile.

But it was too late. The world began to blur, and you felt your body stiffen. Your vision darkened, and the sounds around you faded into the background.

When you came to, you were lying on the floor, surrounded by concerned faces. Matt was crouched beside you, worry etched on his features. “Hey, you’re okay. Just breathe,” he said softly, his voice cutting through the haze.

Kelly was on the other side, holding your hand. “You’re safe, we’re here,” he reassured you, his grip firm but gentle.

As you tried to focus on their voices, the fear began to dissipate. “What happened?” you croaked, trying to sit up.

“You had a seizure,” Matt explained, his eyes never leaving yours. “But you’re alright now. Just take your time.”

Kelly adjusted his position, ready to assist you if needed. “Do you remember anything?” he asked.

“Just… a blur,” you managed, feeling shaky but grateful for their presence. “I’m so sorry.”

“Don’t apologize,” Matt said, his voice steady. “This isn’t your fault. We’ll always be here to help.”

They stayed by your side, offering support as you regained your bearings. Matt kept talking, his soothing words grounding you. “You’re stronger than you know. We’ve got your back, no matter what.”

Kelly nodded in agreement. “We’ll figure this out together. You’re not alone.”

Slowly, you felt the room stabilize, and the tension in your body eased. With Matt’s help, you sat up fully, leaning against him for support. “Thanks, guys. I really appreciate it.”

“Anytime,” Matt said, smiling gently. “Just promise us you’ll take care of yourself.”

“I promise,” you replied, feeling a sense of relief wash over you. With them by your side, you knew you could face anything.

As the night continued, the laughter returned, but this time, it felt different—stronger, filled with the bond you shared. You realized that with friends like Matt and Kelly, you could navigate even the toughest moments, knowing you’d never have to face them alone.

MATT CASEY MASTERLIST

Days like these were the worst.

It was bad enough you’d had to cover for people who weren’t pulling their own weight in the team. But of course, like they said, bad things came in threes. At least it was never just one thing.

Everything that seemed to go wrong, did. Then, there came the finger pointing, the backstabbing, and your boss’ yelling.

You were practically drained by the time the office was emptying out.

Yet, the universe didn’t seem to be ready to let you off for the day.

You’d passed a cafe on your way back, grabbing an ice cream on a whim, hoping that your mood would have improved by the time you saw Matt that evening. You weren’t crazy about ending the day on a less than happy note, and you hated making Matt feel down with you as well.

You’d just taken two steps down the street with the ice cream in your hand when a guy had rushed past, practically crashing into you.

The force sent you stumbling at least three steps backward, and you’d barely managed to stay upright but your ice cream had ended up top down on the street.

“Would you at least watch where you’re going!” The guy yelled.

On any other day you might have ignored him, but you’d had more than enough unreasonable people in your face for the day.

“You bumped into me.” You responded, keeping your voice as even as you could. “And that’s my ice cream you knocked out of my hand.”

The man glared at you, flashing a rude sign at you and muttering about how you were lucky he was in a rush before he continued his way down the street.

That only served to worsen your mood but you headed home anyway, feeling the fatigue of the day start to hit you.

You stood outside the door of the apartment you shared with Matt for just a minute. You weren’t sure if Matt was already home. He wasn’t on shift today but he’d been working on a construction project and hadn’t been sure of his timing.

Just in case, you steadied your emotions as best as you could before you opened the door.

Matt was indeed home, and he heard you the moment the door opened.

“Hey babe!” You heard his voice first, before he appeared before you, leaning in to give you a welcome home kiss. “You’re a little later than usual.”

You smiled back at Matt, feeling your emotions stabilize a little just by seeing him standing in front of you. “Yeah, I just took a little detour to pick up some things.”

Your words sounded lame as you heard them, but even so, you thought you’d handled it pretty well, considering.

Matt, however, seemed to pick up on everything. The look in your eyes, the tone in your voice, or the smile that didn’t fully reach your eyes.

Matt's brows furrowed, just a little. “Y/N?”

You weren’t sure what it was that caused the prick of tears. Maybe it was the soft tone of Matt’s voice, or just the fact that Matt was standing right in front of you.

“Yeah, I’m…” You couldn’t even finish your sentence before Matt pulled you into his arms, your face fitting snugly into his shoulder.

That was all it took before you were a mess, the frustrations of the day seeming to flow out with each tear that soaked into Matt’s shirt.

Matt didn’t ask you anything, merely holding you tight against him.

When your shoulders stopped shaking, Matt spoke, “We’ve got pasta and I can pop out the wine that Kelly brought the last time he was here.”

You smiled through the residual tears. “Sounds perfect.”

That’s how you and Matt ended up on the couch after the meal, the plates forgotten in the dishwasher as you cuddled into his side. The television was on, but you weren’t really paying attention, your head laying on Matt’s chest, close enough that you could hear the regular thump of his heart.

“You want to talk about it?” Matt asked quietly, adjusting the quilt he’d draped over you earlier.

You shrugged but told him anyway, starting to feel a little stupid about your mini meltdown.

“It’s not really a big deal, I don’t know why…”

“Hey.” Matt interrupted you. “If it's a big deal to you, it's a big deal."

You didn’t say anything, merely scooting closer.

Matt’s arm tightened around you. “But I’m glad you know I’m here. No matter what.”

That’s when it hit you, the realization of what had caused the onslaught of tears. The only place you could let go, be yourself and allow your emotions to take over was your safe place.

“Thank you Matt.” You whispered quietly, almost to yourself.

Matt pressed a kiss to the crown of your head. “I love you too.” He responded.

This was indeed your very own safe place - Matthew Casey.

Word Count: 3.5k

Summary: You and Matt Casey had been secretly dating for a while, and it had gone smoothly since you worked at different firehouses. However, you were offered a job at 51 which despite seeming like a great idea, only made everything complicated.

Warnings: hurt/comfort, a bit of angst, a bunch of fluff, pet names, mention of anxiety, protective matt, kissing, happy ending

a/n: my first fic!!!!! (on tumblr that is lol) i used to write a lot on another platforms but haven't written for fun in forever (other than for school, ew lol.) so i might be a bit rusty so just yk excuse that until i get back into my flow :) anyways i hope you guys like it <3

For the last three years, you've been working as a paramedic at Firehouse 20 alongside Violet Mikami. During that time, you've come to know Blake Gallo as a result of his on-and-off relationship with her. Although he's a great guy, what made him even greater is the person he introduced you to about a year ago— your boyfriend, Captain Matthew Casey of Firehouse 51.

Where could you possibly start? His mesmerizing, smile and his charming personality drew you in in an instant. You never realized how the occasional encounters, transformed into intimate late-night conversations. And before you knew it, those late-night talks grew into romantic dinners and memorable dates.

After months of both of you dancing around one another, he finally masked up the courage to ask you to be his girlfriend. Without a moment's hesitation, you instantly said yes.

Six months have passed since then. Both of you had mutually decided to keep it private for some time in order to prevent any interference with your jobs. The only individuals who had known were your respective Chiefs, just in case something happened.

Your Chief also knew you could handle a busier station such as 51. So, he had just offered you the vacant paramedic position that was left after Foster left for Med School.

Initially, you were excited about the offer because it meant working with your boyfriend. However, now you're uncertain about accepting it as you're not sure how he’d react. While you believe he'd be as thrilled as you are, there's this nagging feeling that it would complicate things.

So you decided to call him.

"Hey Matt," You said once he picked up.

"Hi babe, everything okay? You rarely call me during shift." He replied, voice laced with concern.

"Yeah, yeah, everything's fine." You assure him before nervously adding, "It's just... I have something to run by you...”

"Go ahead sweetheart, what's up?"

"You know how Foster left and ever since then there's been an open paramedic spot at 51 for a while now?"

He hums encouraging you to continue.

"Well, my Chief spoke to Boden and they both agreed that I could fill that spot if I wanted to."

"That's fantastic news!" He said excitedly. "Do you want to?"

You sighed. "I do want to. I think it would be nice to work with you and the experience of working at a busier station? That would benefit me, by a lot. I’d be able to learn so much."

"Then what's there to run by me? This is your decision Y/N." Matt questioned.

"It's your house! I don't want to interfere with the little family you all have built and make things complicated considering we'd be working together while dating and what if they take it the wrong way thinking I only got the spot because I'm with you-"

"Hey! Y/N, sweetheart, breathe." He says cutting off your rambling, trying to calm you down.

"What?" you ask, voice exasperated.

"Baby, no one's going to think anything like that. You're an amazing paramedic and you earned your spot because you're good at your job. Also, no one knows that we're together so they won't suspect a thing. We don't even have to tell them yet if you don't want to.” He said reassuringly before continuing, “And you wouldn't be interfering with anything, I can assure you that we'd all love to have you at 51. This is completely your choice though, so whether you want to transfer over here or not, you have my full support, regardless of what you decide."

You smile at Matt's words. "Thank you." You pause for a moment before resuming happily, "Okay I'm going to go tell Chief that I'm accepting the position! I'll talk to you later Matt."

"That's my girl." He says smiling before hanging up.

You swiftly head to your Chief's office and let him know that you completed the transfer paperwork and are ready to begin at 51 as soon as possible. He nods, smiling, and assures you that he will push the request forward.

It was now Monday. Which also happened to be the same day you started your first shift as the new paramedic of Firehouse 51.

God were you nervous.

You had spoken to Matt multiple times and he continuously reassured you that you had no reason to feel anxious because everyone would adore you. So why were you still panicking?

Matt liked you, Gallo liked you, and so did Boden after the short interview you two had.

You had also heard a lot about each of them through Matt, and they all sounded like wonderful people. So the odds of your new coworkers welcoming you with open arms were pretty high.

Yet despite your best efforts, you couldn't shake the feeling of anxiety that was coursing through your veins, leaving you a nervous wreck.

You let out a sigh, trying to calm your nerves as you approached the Firehouse. You bumped into Gallo on the way which instantly relieved your worries. Seeing a familiar face put your mind at ease, melting your fears away, even if it’s only for a moment.

The two of you engaged in an easy conversation as you walked into the building together.

Upon entering, you spotted a table near the rigs with several individuals seated around it. Gallo eagerly ushered you towards them, quickly introducing everyone.

"Squad, this is Y/N Y/L/N, our new paramedic!" He said as you smiled, waving at them.

Gallo then pointed at a tan, blue-eyed man who was sitting at the head of the table. "That's Lieutenant Kelly Severide. Head of Squad and those are his Squad members."

He quickly got up and shook your hand. "Nice to meet you Y/L/N."

You recognized him now. He was Matt's best friend, they'd been through thick and thin together. It was sweet actually, finally getting to put a face to the name you've been hearing so much about.

Gallo took his time introducing you to the other members of Squad, all of whom greeted you with kindness and respect.

As he slipped into conversation with them, you took the opportunity to excuse yourself and find your partner, Sylvie Brett, who you’d be spending most of your time with.

She stood out easily, being one of only two women in the house. You spotted her in the kitchen, chatting with another girl who you figured must be Stella, Severide's girlfriend. Matt had spoken to you about how amazing they were as a couple, and it always made you happy to hear about them. With a deep breath, you made your way over to them.

"Hi!" You smiled. "I'm the new paramedic here working with... Sylvie Brett?" You ask unsurly, turning your head to glance at the blonde hoping you're right.

"Yes, that's me! Hi!" She answered enthusiastically, hugging you. Matt had mentioned how sweet she was but the embrace still caught you by surprise. Regardless, you hugged her back, accepting the kind gesture. Once you pulled away you waved at the other woman who smiled back at you, introducing herself as Stella Kidd.

After conversing with them for some time and getting to know one another, you headed off to the officer quarters with the hope of seeing your boyfriend.

Once you approached the office that was referred to Matt Casey, you knocked.

"Come in." You heard so you stepped inside, closing the door behind you.

"Hi baby," You said, smiling at him. He looked up from his desk, features softening as he noticed you.

"How's my favorite girl doing?" He asked standing up to give you a brief kiss on the cheek.

"I'm great! Everyone here is so nice and fun to talk to. They've all been so welcoming." You answered excitedly.

"See, I told you everyone would love you. What's there not to?" He asked rhetorically, making you smile as he placed his hands on your waist pulling you in closer. Matt's inability to keep his hands to himself never fails to make you laugh. It was all quickly forgotten though when he drew you in for a more passionate kiss when he noticed that there weren't any prying eyes on you.

As time passed, days turned into weeks, and before you knew it, you had seamlessly become a part of them. Each member of the group welcomed you with open arms, and it felt like you had found your place within the close-knit family they had formed at 51. It seemed like you had found a lasting bond and a sense of belonging with everyone there, envisioning a permanent future among them.

You became good friends with Sylvie and Stella, established a nice mentorship with Hermann, and created a sibling-like bond with Severide.

Most importantly though, to your knowledge, no one had suspected your relationship with Matt.

You wanted to say something, you really did. You didn't want him to think you were ashamed of being with him. But you didn't want the people you had grown so close to to think that you were only offered the position because of your relationship with him; even if you were confident that they weren't the type of people to believe that.

It was an ordinary day. You and Sylvie had just returned from responding to a call— nothing too serious, just tending to a man who had been cut by a broken mirror. Together with Sylvie, you bandaged him up and sent him to Med for stitches, wishing him a speedy recovery.

You were restocking the ambulance when Sylvie spoke up, "So, did you see the way that guy looked at you?"

You almost choked on your spit at her statement, not expecting it. "How did he look at me?"

"Oh c'mon- there were literally hearts in his eyes every time you spoke up while bandaging him!" She exclaimed a bit too loudly making you shush her.

"Who had hearts in his eyes?" Matt chimed in as he walked up to you and Brett, joining your conversation.

"No one," You say brushing him off but Sylvie interjects. "This guy we were helping earlier, he totally had the hots for our new paramedic over here." She said, nudging you with her arm in a teasing manner.

"Oh, did he?" Matt asked in a tone that sounded like he was joking but you could see the way his body tensed.

"It's whatever, nothing serious. It's not like I'm going to go on a date with him." You roll your eyes trying to dismiss the situation.

"You should!" Sylvie replies happily, "You're pretty and single. He wasn't bad on the eyes either, if you know what I mean. Go have some fun girl! Who knows, he could be the love of your life." She adds, winking.

Matt gave a half-hearted smile and walked away without acknowledging Brett, leaving her looking up in confusion. "What was that about?" She asked.

"No idea," You say shortly, despite knowing exactly what was going on.

Matthew Casey was jealous.

It was quite surprising because he had never shown signs of being the jealous type. In the past, if another man approached you in his presence, he would politely ask them to leave you alone, making it clear that you were already taken. Or he’d simply put his arm around you in a protective, not-so-friendly manner, letting everyone know that you were his. It never bothered you. You found it cute, actually.

But this? This was different. He had never acted this way, which concerned you.

After you were done restocking the ambo you made your way to his office, hoping to ease the tension.

You sighed as you knocked, hearing a quick come-in before stepping inside. You noticed he had his head buried in paperwork, not even acknowledging you as you came in.

"Matt, honey, what's wrong?" You asked, worried when he still didn't look up at you. You waited for a moment before continuing once he didn't reply, "Baby talk to me."

He sighs before finally looking into your eyes. His ocean blues never failed to make you weak in the knees. So intimidating but beautiful nevertheless.

"I don't want to keep this a secret any longer." He eventually replied, motioning between the two of you.

"I don't want to either but you know we can't."

"Why can't we?" He said, tone a bit sharp, causing you to flinch for a second.

"Because-" you were cut off by a knock on Matt's door making you straighten up.

"Sorry to interrupt, but there's someone here to see you Y/N." Said Severide as he poked his head into Casey's office letting you know before heading out.

You quickly glance at Matt sighing before leaving his office, silently apologizing. You hated leaving mid conversation but this could be important. You noticed him trailing behind you as you walked out but chose not to comment on it.

Once you were outside, you recognized him as the man you had sent to Med earlier. The same man who had 'the hots' for you apparently, according to Brett.

This was going to be a long conversation.

"Hello!" He said, way too ecstatic for someone who had just been discharged from a hospital.

"Hi there, how are you feeling?" You asked, keeping the conversation polite.

"Better thanks to you, you saved my life."

"Oh, you know, no big deal! Just doing my job."

"Well, I was hoping to take you out on a date as a way of saying thank you." He said with confidence, catching you off guard.

"I'm very flattered sir but you don't need to thank me, let alone take me out on a date. I'm happy to help, love what I do." You say, hoping that gets rid of him.

By now, you were fully aware that most of the members of the firehouse were watching the interaction occur from behind you. Hence why you were aiming to wrap it up as soon as possible.

"No, no, I insist. We'll have a great time together!" He pushes.

"Like I said, thanks for the offer but I'm going to have to decline. Feel better." You say, turning around.

Before you had a chance to walk away, he grabbed your wrist harshly. Pulling you backward, making you lose your balance, and almost causing you to fall.

"Woah woah woah-" "Back off!" You hear the men hurriedly interject pushing him away from you before Matt yells, in a tone that sends shivers down your spine. "Get your hands off of my paramedic before I call the authorities. You have no right to touch her, especially after she said no."

Boden hears the commotion and steps out of his office. "What's going on over here?"

"This man put his hands on Y/N after she rejected him Chief. He was just leaving though weren't, you?" Matt replies, glaring at the man making him quickly walk away.

The second that he was out of sight, everyone turned to you. Stella speaks up, "Are you okay?"

"Don't worry guys, I'm fine." You say looking around at all of them, reassuring them that you're okay. "Thanks for the help. I'm sure he won't be coming back any time soon, especially after the way Casey glared at him." You add chuckling, trying to lighten the tense atmosphere around you.

"You'd almost think you guys were dating with the way he attacked him to defend you," Severide commented casually, using a tone that sounded like he knew something. Which you decided to ignore for the time being.

At the mention of your boyfriend though, you looked up hoping to catch a glimpse of him but noticed he was nowhere to be found which alarmed you.

As the crowd dispersed and engaged in their own conversations, you discreetly slipped away and made your way to visit Matt in his quarters, marking this as your second visit there in the last half hour.

This time though, you didn't even bother knocking and simply walked in.

When he noticed it was you, he quickly stood up concerned, “Are you okay? Did he hurt you?”

“Oh, I'm alright. Don't worry, it was nothing I hadn't dealt with before in this line of duty, you know how men can be sometimes.” You answered, nonchalantly.

You both stayed quiet for a moment, not knowing what to say. Finally, you decided to break the silence, “I'm sorry, Matt. I don't want to argue with you, so if it'll make you happy, we can go tell them right now.”

He sighed, turning around in his chair to look at you, “Y/N, this isn't just up to me, we’re in this relationship together. We have to make decisions like these as a team. I love you and I want everyone to know that but if you're not taking this seriously and want to go on that date instead then-”

“No! This is serious to me Matt, I love you and you know that.” You cut him off before he's able to finish the sentence. “I have eyes for you and only you, no one else matters to me but you, Matthew Casey.” You add firmly, making sure he understands that.

“Then what’s the issue here?” He asks, tired of the constant back and forth you've been having today.

You sigh and sit down on the edge of his bed before replying, “I just- I've become so close to everyone here in the last few weeks and I don't want their opinion of me to change after they find out that you and I are together. I don't want them to think that I'm only here because of you.”

“Baby…” He says in a softer tone, getting out of his seat to come sit next to you.

You don't look at him once he's sat beside you, opting to look at the floor instead.

“Hey, look at me.” He gently says taking your hands in his, grabbing your attention.

You hum as you bring your eyes up to meet his.

When he's sure you're not going to look away, he starts speaking, “Listen to me, everyone here? They're the most amazing and supportive group of people you'll ever meet. They won't dare say anything of the sort because they'd be beyond happy for us. And if they slightly even think about it, I won't hesitate to go all ‘Captain’ on them.” He says, making you chuckle.

“Besides, I don't want idiots like that guy who can't take no for an answer, hurting you again for a nonexistent chance of taking you out.” He adds.

You lean forward, pressing your forehead against his, and after a moment passes, you mutter a simple, “Okay.”

“Okay?” Matt questions.

“Yeah, okay, let’s tell them.” You reply, nodding enthusiastically.

“I want everyone to know that this handsome man right here,” You say pointing at his chest with a teasing tone, “Is of the market and mine only.”

“Yeah?” He grins.

“Mhm,” You say with an even bigger smile, before leaning in to press your lips against his.

As your lips finally touch, a wave of stillness washes over you. It feels as though the entire world has come to a halt and all that exists is the shared connection between the two of you. At that moment, nothing else matters except for the feeling of his lips against yours.

His delicate hand caresses your face, making you smile into the kiss as you pull him in closer, wrapping your arms around his neck. There's no need to hide your love for each other anymore, allowing your affection for one another to be expressed freely without the fear of secrecy. The rush of emotion flowing through you is intoxicating and God, it is an exhilarating feeling, one that you had never felt before.

Before the kiss could progress any further, you heard cheering outside making you pull away. You glance out the window to understand what the fuss is about when you notice that the blinds were left open, meaning that all of 51 just saw you kissing Matt.

Your cheeks flush with warmth, causing you to bury your face in Matt's shoulder as he laughs at your reaction. He wraps his arm around you, pulling you closer in a tight embrace.

You look up at him, mouthing an ‘I love you,’

He whispers back, “I love you too.”

He quickly leans in for one more peck against your lips, before bracing himself for all the questions you're about to receive once you head outside.

“You guys were betting on us?” You asked amused, raising your eyebrows at the exchange of money happening right in front of your eyes.

“Well, what were we supposed to do!?” Cruz exclaimed defensively, earning a giggle from you.

“I mean, we all knew you guys were head over heels for each other, that was obvious. We just didn't realize you had been together prior to all of this.” Added Ritter, shrugging.

“I can speak for everyone though when I say that we are all very happy for you two.” Said Herrmann, making everyone nod in agreement.

As soon as the initial stage of shock died down, Stella and Sylvie rushed over to you, enveloping you in a group hug, requesting all the juicy details. While Kelly simply gave Matt a supportive pat on the back, smiling at his best friend.

Soon, the questions regarding your relationship began pouring in. Matt drew you closer, wrapping his arm around your waist as he answered each of them one by one. You rested your head on his shoulder, closing your eyes briefly, basking in the serenity.

And at last, you found yourself finally feeling at ease. Your family knew, and they were happy for you. Which is all you could ask for.

Fix You-Part 1

Kelly Severide x Reader x Matt Casey/ Sevasey x Reader

You get sent to Firehouse fifty one as a temporary placement when a paramedic is needed. Your first day you meet the house Captain and Rescue Squad Lieutenant.

“Where’s your placement?” your sister asked as you balanced your phone between your ear and shoulder, trying to gather everything you needed to get out of the door. “Firehouse fifty one. They need a new partner for Brett after Dawson moved. I’ve worked with the rig in passing but this will pretty much be my first time working with the truck or rescue squad” you told her as you rushed out of your apartment, locking the door behind yourself.

You’d met with Chief Boden already along with Sylvie Brett but when you’d met with the two of them it had only been them. Today would be your official introduction as a temporary member of the house. You knew most of the firemen by name and face at the very least but you would be there for ten months. You’d hopefully build at least a few friendships.

You parked your truck across the street where Boden told you it was ok then grabbed your gear and headed over to the station house. Sylvie spotted you and stepped out of the bays to meet you halfway “Hey Y/N” you grinned “Sylvie! Glad you’re here already. I would’ve hated to walk into this without at least one friendly face at my side” she laughed and slipped her arm through yours “They’re not that bad, really”

You raised an eyebrow and she shrugged “Ok, well they’re not worse than any other house” you laughed “Now that I believe”

The two of you walked into the bays and you spotted a few men sitting around a table, one in a freaking recliner. “Who’s the grandpa?” you asked without thinking about it and when he turned around you wanted the floor to open up and swallow you. It was Squad Three Lieutenant Kelly Severide. A grin slipped onto his face as he stood up to face you “Who’s the spitfire Brett?”

You recovered from the embarrassment fast enough to smirk “Spitfire huh? I kinda like that. Name’s Y/N. I’m the temp paramedic here as a partner for Brett until Boden finds someone who’s a fit” he nodded as you held your hand out. He shook it then winked at you “Think I’ll stick with Spitfire, suits ya just fine” 

Matt Casey, the house Captain, walked out behind him and put a hand on his shoulder “Is this idiot bothering you ladies?” you shook your head “My fault really, I called him a grandpa” 

A grin split Matt’s face at that as he cut his eyes at Kelly, affectionately running his hand over the other man’s grey hair “Grandpa huh?” “Don’t you dare babe” Kelly replied then nodded at you “This is Y/N, the temp para but I think we’re gonna call her spitfire”

Matt looked back at you “Spitfire?” you shrugged “I like it” he nodded “Then it’s settled. Sylvie will show you around, get you a locker. If you need anything feel free to holler at me or Kelly” you nodded “Thanks”

Within about a week or two  you were on a first name basis with everyone you were on shift with and knew everyone who worked out of the station house. It was a family of sorts and even though you were only a visitor they were welcoming you in with no hesitation. 

“Why are you working as a temp?” Cruz asked one day when all of you were picking at breakfast before any calls had come in. You shrugged and sipped the coffee in your hands “Haven’t really found a house that fits me. This way I’m still doing what I love and helping houses that need it in the meantime” Kelly leaned back from where he was sitting across the room next to Matt and you knew the moment he grinned he was about to tease you “So you’re a stray sniffing around for a home?” 

Matt slapped him behind the head then looked at you “I’m sorry. I’ve been trying to house train him for years but it hasn’t taken” you laughed as Kelly rubbed his head and cut his eyes at his boyfriend. “It’s fine Matt, he isn’t wrong really”  “Think you may stay here?” Sylvie asked and you shrugged, feeling very much like you were in the hot seat “I don’t know yet. I mean I like working here so far but it’s a little too soon to tell”

Matt met your eyes and you knew he could tell you were uncomfortable because he cleared his throat “That’s enough with the twenty questions” you shot him a small smile as a thank you as everyone turned their attention back to their food or other conversations. 

A call rang out for a structure fire needing the truck, rescue and ambulance so everyone was on their feet and in motion, any semblance of breakfast long forgotten as you headed for the bays. 

You ran past Matt and smiled “Thanks for that” he nodded so you hurried to hop into the driver’s seat of the rig as he ran to the truck and Kelly ran to the rescue squad. Sylvie cut her eyes at you as you fell into the line of vehicles as they pulled out onto the road “I think you’ll end up staying”  You laughed lightly “That you thinking or hoping Brett?” She shrugged “Little bit of both?”

You walked into your apartment and considered for a second just crashing across your couch instead of making it to your bed but your phone chimed with a text from Sylvie We’re going to Mollys. You in?

You were tired but it was a friday and you were off the next two days…screw it. You texted back Meet ya in twenty? And she replied See you there!

____________________________

You walked into Mollys and spotted Sylvie sitting with a few women from med and the twenty first so you headed towards her. You smiled when Kim Burgess greeted you “How’s fifty one treating you?” you cut your eyes at Sylvie then nodded “Best partner I’ve had yet” and Sylvie grinned broadly. You looked around “Where is the rest of your unit Burgess?” she shrugged “Adam is currently retrieving our drinks, we got you one too. Jay and Mouse are over there in a booth with Fireball” she nodded and you saw the men in question with their girlfriend. You knew Fireball well, she was a trauma nurse at Chicago med. One of the best you’d seen. Probably from her time as a combat medic, from what you’d gathered that was how the three of them had met.

“Where’s the other two?” you asked and she grinned “Kevin has a date with that new nurse from med that just moved here from scotland and Firecracker stayed in tonight with Will and Connor”  you nodded as Adam made it back to the table carrying the drinks and passed them out, shooting you a smile “Here ya go spitfire. If it’s not right, blame your partner” you laughed “It’s fine Adam. A free drink is a free drink. Especially one I know I can trust”

____________________

You and Sylvie had Adam and Kim laughing about a call you responded to where a frat guy got his head caught in a stair railing. “He was breathing fine, not in distress but I swear it reminded me of something that would’ve happened in a movie from the eighties” you laughed around your drink.

You’d only drink two with alcohol then switched to soda but the company was good so you were still enjoying the night out. “There’s our medics” you heard Matt’s voice and cut your eyes up with a smile “Captain” he shook his head “We’re not at work, just call me Matt” you nodded “Ok Matt” Kelly grinned at you from next to him “And you always call me Kelly anyways” you laughed “That’s cause Matt always acts like a captain. You only act like a lieutenant when we’re actively on a call”

They nodded to the table “Can we join you four?” you shrugged and looked around. Sylvie shrugged and Adam patted the table “Sure” Kelly went to grab them drinks as Matt sat down next to you. “So, spitfire, how long is your contract for anyways?” you grinned “Trying to get rid of me already?” he raised an eyebrow so you grinned “Ten months unless I put in a request to stay. Boden said I’d have that option as soon as six months hit”

Sylvie gasped “You did not tell me that” you grinned “Because I don’t want the twenty question game to start back up” Matt shook his head “It won’t. I won’t let it” “Thank you” you replied and turned back to your previously abandoned conversation with Sylvie and Kim as Matt started talking to Adam then Kelly came back over and joined their conversation as well. Maybe you could find a place at Fifty one? 

It was still a little soon to tell but it was starting to feel like home already.
