#ominis x reader x sebastián

[sallownights]

Hi - I absolutely love the Taylor Swift and Hogwarts Legacy crossover you have going on here, it’s right up my alley!

Anyways, I had this idea for a fic based around “The Way I Loved You”; reader and Sebastian aren’t together anymore but she’s missing his antics.

Double points if Ominis is the ‘sensible and endearing’ one 🩷

the way i loved you

word count: 2.7k

CW: angst, fighting, fluff, mentions of sex

A/N: i don’t know where the fuck i ended up going with this. i feel like i blacked out while writing. this song, SLAPS

pairings: sebastian x f!reader, ominis x f!reader, sebastian x f!reader x ominis

The silence of the Undercroft. No spells. No fire. Nothing. Y/N brings her robes closer to her, trying to trap her warmth against her.

She came down here when she missed him. It didn’t matter if they broke up. It didn’t matter if she had a new boyfriend. She missed him.

It’s not like Ominis isn’t kind to her. If anything he was better for him. He’s sensible, kind, and endearing. There were so many words to describe him. Just thinking about him brought a smile to her lips.

It always comes back to Sebastian though. Sure, they had their fights. Often. They were, by no means, not a toxic couple. He would be jealous whenever Y/N decided to help Garreth with something. When she and Amit would work on Astronomy projects together. When she would stay out late with Poppy.

“I’m not having this conversation. Not again.” Y/N rushes past him, walking towards the castle. She had just returned from a trip with Poppy.

“Of course, you don’t want to talk about this.” Sebastian rolls his eyes. Y/N’s hands ball up into fists.

“Oh come off it Sebastian! I’m not fucking cheating on you. I can have friends.” He scoffs.

“You only spend time with them. I feel like I never see you.” He says. Clouds rush by in the sky, the night was dark. Darker than normal. The moon wasn’t visible. Thunder rolled throughout the clouds as it started to rain.

“I was with you all day yesterday! All day. Does that mean nothing to you?” The rain came down hard. Both of their robes quickly getting soaked.

“That’s not what I’m saying. I just miss you!” Sebastian throws his arms out, exasperated.

“You have a funny way of saying that!” They stand far enough away for there to be awkward tension. They’re both breathing, hard. His eyes stare into hers as best he can, the water pouring into them, making him blink.

They rush over to each other, smashing their lips against each other. Their hands were roaming around the other's body, not knowing where they were exactly. It was just important that their hands were on the other.

The kiss deepens, Sebastian, dipping Y/N, holding her tight. He picks her back up as they pull apart, their foreheads touching.

“This is a stupid fight,” Sebastian, holds her arms and pushes her nose with his.

“I’m sorry,”

“I just need you to trust me, Seb,” He nods, wrapping his arm around her shoulder, and starting to walk her back to the castle.

“We’re gonna get insanely sick,” Y/N giggles.

“I know.”

Y/N smiles at the memory. She remembers them shivering walking back to the common room. He held her close though. She misses it. Misses him.

They never stopped having that fight though. When they decided to break up, it was a bit of a shock to some people. Ominis wasn’t surprised. He knew they were having trouble. Knew that they were constantly bickering.

Sebastian and Y/N’s love was like a hurricane. Mostly stormy with a moment of peace every now and then.

She missed when he would do random things for her. Or surprise her by taking her into the Forbidden Forest for little picnics. It always seemed as if he would do anything for her.

“How much farther?” Y/N walks with one hand stretched, in case she runs into something while the other hand grips Sebastian’s for dear life.

“Darling, you’ve asked me this four times already,” he chuckles. Y/N huffs.

“Well, we’d be there already if you didn’t put a stupid blindfold on me.”

“That ruins the fun of a surprise,” Sebastian takes both her hands, beginning to walk backward. He stops suddenly, causing Y/N to stumble a bit but he keeps her upright. He gets behind her, taking the blindfold off, wrapping his hands around her waist.

When Y/N opens her eyes, she blinks a few times, getting used to the light again. When her eyes focused she sees a hidden waterfall nestled among the trees. The water cascades down a series of rocky ledges, creating a symphony of gentle splashing and bubbling.

But what catches her eye is the water itself. It is so crystal clear that she can see straight through to the bottom. And as the sunlight filters through the thick canopy of trees above, the water seems to glow with an ethereal light, creating an otherworldly ambiance.

The pool at the base of the waterfall is surrounded by smooth, moss-covered rocks, and the water is so invitingly clear that she can't resist dipping her hand in. It's refreshingly cold and seems to rejuvenate her soul with every touch.

As she gazes up at the waterfall, she notices that the rocks around it are covered in lush greenery and wildflowers, and she can hear the sweet chirping of birds and the rustle of leaves in the gentle breeze. It feels like a hidden paradise, untouched by the modern world.

She takes a deep breath and lets the beauty of the place wash over her, feeling grateful for the chance to experience such a magical moment in nature.

“Sebastian, how did you find this place?” Her voice quiet, she turns around to look at him.

“I found it earlier this week, I wanted to show you it. Do you like it?” Y/N nods, hugging Sebastian tightly before giving him a quick kiss.

“It’s beautiful,” She turns around again, watching the water cascade down. She takes a deep breath, breathing in the fresh air. Sebastian’s cologne gets mixed into the air when he steps behind her, wrapping his arms around her and kissing her neck.

“Seb,” She says, placing her arms on his.

“Yes, my darling?” He asks before he nips at her neck.

“Did you take me here to fuck me?” She turns around, his eyes dark.

“Maybe,” He smirks before crashing his lips against hers.

Y/N smiles again, it really was a magical day. The waterfall was kind of a perfect place for them, she would still go there sometime, once she had figured out how to get there. It was a place she would go after they fight. More so when she was in the wrong and she didn’t know how to apologize. He would sometimes find her there, just sitting on a moss-covered rock, her eyes unfocused as she thought.

He would sit with her until she was ready to talk. He could be furious with her and just sit with her. Towards the end of the relationship though, he stopped looking for her after fights. The energy to keep going was dwindling quickly.

Now, things were awkward. Sort of. It felt awkward. Ominis was there for both of them after the breakup. Y/N would spend nights crying in his arms in the common room. They started hanging out more and more after. Sebastian would join sometimes. They ignored each other for a while, just speaking to Ominis. After a few projects in Transfiguration, they started speaking again. It was still tense between them but not nearly as much. They respected their old relationship without talking about it.

Y/N wondered if he missed her too. If he spent nights thinking about her. She does feel bad that she started dating his best friend. However, she loved him. Ominis was nothing but kind, he was always so caring. She couldn’t help but miss Sebastian though. He was so fun. He just… couldn’t trust her. She also would go out into the forest for hours at a time without telling anyone. No wonder he didn’t trust her. She promised she would tell him and she never did. But he was jealous of her friends. It was a bad match.

“Love?” Ominis’ voice calls out in the Undercroft.

“Hi,” she calls back, her voice cracking. She brings her hand to her face, realizing tears have been spilling out of her eyes.

“What’s wrong my darling?” Ominis walks over to Y/N, he holds her hands gently. Not wanting to harm her.

“I’m… just sad.” Y/N drops her head, tears falling faster.

“What’s making my dove cry?” He brings a hand to her face, wiping some of her tears away.

“I… I miss Sebastian. I miss how he and I were and that’s so unfair to you. I just… I miss him so much. I know we weren’t good together but it feels like part of me is missing. But you… you fill a different part of me.” She sobs, turning away from Ominis, and cries into her hands.

“Darling,” he places a soft hand on her shoulder. “I know you miss him. It’s okay.”

“No! No, it’s not. I love you so much and I… I shouldn’t be thinking about him.” She sobs into his chest. He runs his hand up and down her back, whispering comforting words into her ear.

“I know, I know, love. You know he still loves you, darling,” He holds her head as she begins to cry harder.

“The problem is I do too!” Ominis shushes her as she sobs, whispering that it’s alright and he knows.

“You know if you want to be with him you can be,” Ominis says calmly.

“I don’t want to leave you though,” Her sobs beginning to subside.

“Darling, you know I have feelings for him as well,” Her head shoots up to look at him. His was was stoic, a slight frown on his face from her crying.

“Y-you do?” True confusion comes across her, she realizes that it makes sense. They had been so close for so long. She’s also almost 99% sure they kissed at a party once.

“Yes, darling,” he chuckles a bit. “Before I loved you, I loved him. I think I still might.” She nods, wrapping her arms around him. They stand there, in silence, Y/N sniffling every now and then.

“So… do we tell him?”

“Would you like to? You would both have to change how you act in a relationship.” Ominis’s voice is calm. It always was. He was good at making her feel so comfortable.

“I think I want to… and I want to be better to him. I put a lot of blame on him but I could've been better too,” Ominis nods and kisses her softly. “So, would we all just… date… each other?” Y/N’s voice is uncertain, she really didn’t know what was happening. Her head was swirling. It was hard to believe that if Sebastian wanted to get back together and wanted to be with Ominis, she could be with her two favorite people.

“Well, let’s go find him. I was just with him in the library, I’m sure he’s still there.” Ominis takes her hand in his and leads her out of the Undercroft. The walk to the library was normally a peaceful and meditative experience. This time, there was an excitement and nervousness as Y/N’s steps fell in with Ominis’. As they make their way through the castle, they could hear the soft sounds of their footsteps echoing in the stone halls, and the occasional rustle of robes as other students pass by.

As they enter Central Hall, Ominis squeezed her hand, entering the library. When you enter the library, it's a quiet atmosphere. Broken only by the occasional rustle of pages or the scratching of quills on parchment.

The space itself is vast, with towering bookshelves stretching up towards the ceiling and long, polished tables scattered throughout the room. Soft lighting illuminates the space, casting a warm glow over the books and creating a sense of tranquility.

They climb the spiraled stairs, stumbling a bit in their haste. When they reach the top, Y/N’s eyes scan for Sebastian, spotting him sitting by himself, writing quickly. She yanks Ominis and they start rushing over to him. Sebastian looks up at the noise, seeing Y/N and Ominis. A few different emotions flash over him. Jealousy at them holding hands. Worry at Y/N’s puffy and red eyes. Confusion by the smiles on their faces.

“Hey, is everything alright?” Sebastian’s voice is quiet, he can’t get kicked out of the library again. He didn’t want to study in the common room. Imelda kept bugging him about Y/N and he couldn’t handle it.

“Yes, can we sit?” Y/N says, clearly excited about something. Sebastian nods. Y/N and Ominis split apart, moving chairs to sit directly next to Sebastian. He looks at both of them, confused. He hadn’t sat this close to Y/N since they’d broken up and Ominis doesn’t sit very close to people unless he likes them.

“What- what’s going on?” Sebastian says, looking between the both of them. Ominis takes one of Sebastian’s hands, Y/N following suit. Sebastian’s heart rate picked up. He could feel it pound against his ribcage.

“Well, Y/N and I had a… talk… about something. We wanted to run it by you.” Sebastian turns and looks at Y/N and she nods.

“O-okay.” Ominis makes a motion for Y/N to talk about what they had discussed earlier.

“Well, I was in the Undercroft earlier… I was thinking about you and how I,” her face heats up, a pink blush dusting her cheeks. “How I miss you.” Sebastian started to blush as well. He had missed her so much. He knew he fucked up. They both did.

“I miss you too, Y/N,” Sebastian looks to Ominis, trying to gauge his reaction, but Ominis is just smiling.

“So, then Ominis and I started talking about you…” Y/N looks to Ominis as he leans down to kiss Sebastian’s hand.

Sebastian’s head was reeling. He was with his best friend since he had arrived at Hogwarts. Ominis showing Sebastian more affection than he ever had. Then, his ex-girlfriend who he was still in love with saying she missed him. He was absolutely certain he had fallen asleep while doing homework. He looked forward at his notes but they were coherent.

“Now, I am aware this may sound… odd…” Y/N continues before Ominis speaks up.

“It’s actually quite common in certain wizarding communities.”

“Oh! Well, I suppose it’s common in some places…” Y/N giggles. “Anyways, we were thinking maybe we… could all be… together? If that’s something you find suitable.” Sebastian’s eyes go wide, confused out of his mind on how this is happening today.

“Like… date both of you?” Ominis and Y/N both nod.

“I’ve liked you for some time, just wasn’t going to tell you. Then, when dove was crying about you, I figured it was time to admit it to someone else.”

“You didn’t have to tell him I was crying, Omi.” Her voice lowers.

“If I can interject, you look like you’ve been crying.” Y/N’s eyes widen and quietly says,

“Oh.”

“It’s alright, you still look beautiful,” Sebastian takes his hand from hers and places it on her face. There was an immediate sense of familiarity. Of home.

“I’m sorry,” He whispers, quietly.

“I’m sorry too,” Sebastian and Y/N look at each other before turning their attention to Ominis.

“Well, I do find this ‘arrangement’ suitable. If you both would have me.” Sebastian squeezes Ominis’ hand. Y/N giggles and kisses Sebastian softly. She had missed this. Missed him. He was hers and she was his again. They were both with Ominis too. Y/N could feel her head spinning, her heart feeling full and fuzzy and the men in front of her. Sebastian pulls away and leans in to kiss Ominis, which he gladly accepts. Y/N leans back, happy that she's with the two people she loves dearly.

“This is not what I had planned today,” Sebastian says when he and Ominis pull apart.

“This is the last thing I expected, but it’s certainly not a bad thing.” Ominis smiles and walks over to Y/N giving her a small kiss on the head, playing with her hair.

“So, anything you want to do?” Sebastian asks the two of them.

“Oh! Oh, we should take Ominis to the waterfall. It’s so peaceful there.” Y/N closes her eyes, imagining the cold water and sound of rushing water.

“Oh, is that the waterfall Sebastian and you used to have se-” Ominis says before Y/N covers his mouth.

“Alright, let’s go!”

I like a request of ravenclaw fem Reader and Sebastián with Ominis trap in a tomb and after getting chased by the inferi.

Sebastian and the Reader had to guide Ominis to the hallway filled with traps since which was stressful for the two of them. He manage to get to safety

I didn't know if you wanted it to be romantic, so I took the liberty of making it a Seb x Ominis fanfic, written through the Ravenclaw's perspective :)

Contains a spoiler for Sebastian's questline, although it's one sentence!

I hope it's to your liking! Can also be read on my Ao3

Absolute madness - Sebastian x Ominis (+ Platonic!Ravenclaw!Female!Reader)

Disturbing the graveyard had been a bad idea from the start. The Ravenclaw girl knew it from the start, but when Sebastian Sallow had his mind on something there would be no way to change his mind. So, she sighed and asked Ominis to join them so they could both make sure their friend got out unscathed. As a result, they were now running from inferi. 

“Over there!” She yelled, pointing at a tomb door that was cracked open ever so slightly. With a flick of her wand, the door opened and the three of them ran inside. Another flick of her wand caused the door to close, barely in time as there was one inferius who got the heavy door slammed shut in its face. She took a second to take a breather, eyes desperately trying to adjust to the darkness. 

“Lumos,” she whispered, causing the tip of her wand to glow. She looked around to look at her friends. Ominis was leaning against a wall, bent over as he tried to catch his breath. Sebastian sat on the floor, also out of breath. “Everyone okay?” She asked her friends, looking around for a way out. There was only a path that led down and away from the door. Probably for the better. She couldn’t help but feel curious as to what the path was leading towards. Both Slytherin boys made a noise to signal that they were okay. 

“Note to self; don’t go to any graveyards ever again,” Sebastian said while getting up again. He dusted off his trousers and robe. The girl smirked.

“It’s almost as if you have two friends who told you not to do it.” 

“And yet, you’re still here with me.”

“Cut it out, you two. There’s a time and a place for jokes and it’s not right now,” Ominis intervened, probably for the best. The Ravenclaw knew they’d keep making remarks to each other until one of them caved. Which didn’t happen quickly nor often. Her eyes scanned the room, but were pulled in by the pathway. Something stirred in her stomach as she squinted in distrust. 

“The only way out is through there,” she said.

“I figured as much.” Sebastian walked towards the pathway. He almost took a step onto the cobblestone floor, but his friend stopped him. He frowned as his brown eyes found hers. “What are you-?”

“I read about tombs like these in some books. They’re usually filled to the brim with traps,” she explained whilst she picked up a pebble. She threw it into the darkness of the hallway. The sound of stone on stone echoed back towards the trio, followed by the whistle of arrows ricocheting off the walls. Sebastian swallowed nervously. The girl shot him another I told you so glare. 

“How barbaric and honestly, quite primitive,” Ominis commented. Sebastian chuckled a bit too loud at his friend. This made the Ravenclaw raise a brow, at which Sebastian blushed and shrugged. She knew of Sebastian’s terrible crush on his oldest friend and had been trying to get them to confess to each other. She knew Ominis was crushing just as hard on Sebastian, but they were too dumb to see the other’s feelings. To be frank, they both weren’t very obvious about it unless you knew them personally, but Sebastian was the one to crack the most around Ominis. Laughing a little too hard at Ominis’ jokes was one of those cracks in Sebastian’s behaviour that made it obvious to anyone with ears that they were deeply enamoured with each other. 

With a sigh, she pointed her wand at the doorway. There was a handy system in place that would make a boulder come down if anyone stepped through the doorway. The boulder was round too, so besides the arrows flying at you, you’d be chased by a gigantic stone that could certainly crush you. “Lumos maxima,” she mumbled, lighting up the rest of the hallway. It was not a long hallway by any means. She could see the back, with a ladder now clearly in view at the other side. “I think we can make it by simply running.” She concluded, turning towards her friends again. 

Sebastian gawked at her with his brown eyes. “Are you out of your mind?” He asked, clearly surprised and a bit offended by the suggestion. “We’re going to be killed for sure!” 

“Hey, I’ve heard this before. Something something unforgivable curse to open a door in a certain scriptorium one Sebastian Sallow suggested we visit?” She sneered back, a bit sick of how hypocritical her friend was. Sebastian groaned.

“I’ll do it. But someone will have to guide me, as we can’t risk that I run into a wall,” Ominis said, determination clear as day on his face. The girl smiled a little bit at this. Oh Ominis, always the voice of reason of the three of them. 

“Ominis, this is madness!”

“Oh please, you’re not one to talk about madness,” Ominis suddenly grabbed Sebastian’s hand with a small smile. “You should guide me, with our friend in front of us guiding the way.” The red that took over most of Sebastian’s face was incredible. If only Ominis could see how hard he was blushing, the girl thought to herself with a smug smirk. That was another one of Sebastian’s cracking points; physical touch. Which also didn’t happen often, as Ominis usually refrained from touching anyone at all. 

“Fine, fine,” Sebastian caved. He squeezed Ominis’ hand and nodded towards the Ravenclaw. She nodded back. 

“On three?” Sebastian asked. 

“On three.” She repeated affirmatively. “One… Two… Three!” 

The three of them ran through the hallway as fast as they could. The girl squealed when she heard the boulder fall down and roll after the three of them. Fortunately for her, she reached the recess with the ladder in no time. She started climbing up, not looking back to see if the boulder would crush her friends. 

It obviously didn’t, as she heard the boys climb up the steel ladder as soon as she had made space. The boulder came to a halt with a loud bang against the stone. A lid was what was between the three of them and the outside world. She threw herself to the ground and made an inhuman happy sound. She turned on her back to look at the stars with a big smile on her face. Then, she looked up to watch her friends. Just in time, as Sebastian went in for a hug. Ominis had different plans, as he crushed his lips against Sebastian’s. The Ravenclaw girl blushed and looked away, giving them privacy. 

“I’m so glad we made it out alive and unharmed,” She heard Ominis whisper after a little while. Sebastian made a noise that sounded like he agreed. 

“Mhm…”

Her eyes crossed the duo again and she smiled softly at how her friends finally kissed, even if she found it awkward that she was there to witness it. Oh well. She could use it as a story for their future kids. “Uhm, boys, I’m glad you guys are finally confessing, but I feel like it’d be more appropriate if you’d do it in private, away from my eyes,” She got up and tucked her wand away in her robe. “You guys are too sweet, it’s disgusting. Congratulations, though.” 

Sebastian smiled and looked at Ominis. 

“Can’t believe it took a giant boulder for us to fess up.” 

“Your head is kind of like a giant boulder.” 

“Hey!” Sebastian pouted jokingly. “Ominis, she’s being mean…”

“You kind of deserve it for keeping me waiting for this long,” Ominis let go of Sebastian but took his hand again. “But she’s right. We should go back to school, as I have multiple thoughts in my head that I want to do. None of them involve standing around with prying eyes, all of them involve your lips and mine.”
