here's part one and part two though this piece was inspired by this

"Why do I need to wear a dress?"

Hoshina Soshiro glances up from where he's lounging on your bed. You've already pulled on the dress, of course, and he watches with probably way too much interest as you tug and adjust the way it drapes along your body. It's pretty. It fits perfectly, though you have no idea when Soshiro learned your measurements enough to show up at your door with such a gorgeous dress hanging from his fingers. Maybe he got them from Okonogi-chan?

"You'll be walking 'round with me and the Captain, egg tart, so you've gotta look the part," he says idly, though you can feel the burn of his stare along the newly exposed skin of your back. "And don't forget the heels!"

You glance at the cute, strappy heels he left by your mirror and frown. "If I wear those, I'll be taller than you, Soshiro-kun."

"Aw, that doesn't matter," Soshiro says. He sits up and you look away from the flex of his incredibly defined abdominal muscles beneath his compression shirt, which he apparently wears all the time, even under his formal dress uniform with all its tassels and buttons.

God. Embarrassing. You really need to get your staring issue under control.

"I can fight whoever looks at ya."

"Wha— ?" Heat sears across your face as you splutter and spin around to face him. The skirt of your dress twirls with the movement and you catch his gaze snapping down to your thighs. "Why would you need to fight anyone?"

"Hm?" You take a step back as he gets up and stalks over to you, holding your breath subconsciously as he kneels at your feet and takes one of the heels in hand. Your room suddenly feels warmer, the air hushed, as if the two of you are the only ones who exist in the entire universe. Soshiro chuckles quietly and shoots you a grin that makes your knees feel wobbly.

"Soshiro-kun?"

"Well, 'course I'm gonna fight for ya, apricot," Soshiro says. You flinch as he reaches out to grip your calf, the rough callouses on his fingers scraping lightly as he lifts your leg and slides your foot into the shoe. "You're my best friend, yeah?"

And I'm just a simple man in love goes unspoken as he carefully ties the silk around your ankle to keep the shoe in place. You wobble a bit at the balance and he glances up from beneath his violet bangs. "Hold onto my shoulders," he says quietly, reaching for your other leg. "Don't worry, I've got you."

"S-Soshiro-kun, I can put these on myself," you mumble, heat flaring up your spine at the careful pressure of his fingers on your ankle. He lifts your leg and you grab abruptly at his shoulders, fingers digging into the thick muscle there as you regain your footing with his support.

Soshiro lets out a breath. "I know," he says simply. "But I wanna do it."

Is this what men do when they're in love? You wouldn't know — the only man in your life you've ever cared about is right in front of you, and he's refused to elaborate on his strange statement no matter how many times you've asked. You have a feeling he means it, though.

Like, really means it. You love Soshiro — of course you do. You've always loved him. But lately it's felt… different.

Still comfortable. He's still your biggest supporter and vice versa, and he still knows exactly how to cheer you up and make you laugh. You know all his ticks and tells, and you take great pride in taking care of him while he's looking out for everyone else.

But at the same time… it's uncomfortable.

These little touches — they're new. The way his gaze lingers on your body is also new. Or… maybe you've just never noticed before. It's not a bad thing. But it makes you feel strange and fluttery inside and you catch yourself daydreaming about what it'd be like to actually get a hickey from Soshiro. Your best friend.

You stare down at the top of his head and try to repress a shiver as he skims up your legs to where your skirt rests against your thighs. His touch leaves behind a trail of warmth that burrows deep. "Um— ?"

"Ya look real pretty like this," he says. You're still holding onto his shoulders as he rises from his crouch, your entire body hot and hyperaware of how close he's standing once he straightens. "I could really just eat ya up." The smirk on his face makes your heart thump painfully in your chest, but he doesn't give you a chance to question it before he's grabbing your hands and spinning you around in a little twirl.

"S-Soshiro!"

Your best friend laughs as you wobble precariously before regaining your balance, your hands gripping his in a vice as you stumble to a stop. The familiar sound makes everything feel lighter, the heat simmering into something loose and… painful. Your chest aches. "Whoa, lollipop, watch your step!"

"You did that on purpose," you accuse, but you giggle anyway at his lopsided grin. It's bright and undeniably fond, a smile that features in all of your memories together. "You still haven't explained why you'd need to fight people, y'know."

"Let's just say I've got my work cut out for me with such a gorgeous partner," Soshiro says, looping your arm through his and angling for the door. Is he… trying to sweet talk you? Does he think that'll make you forget about his intention to brawl during the meal? "Ya ready for dinner, beansprout?"

"Hold on, don't forget your jacket," you say. He lets you step away to snatch up his formal dress jacket, though his hand hovers, stretching out towards you as you turn back to help him into it. You slip his buttons into place carefully, smoothing out the dense fabric and ignoring your warm face as he rests his hands on your hips to keep you steady. "There! Now we can go to dinner, Vice Captain, sir."

Soshiro's hands tighten at your waist. "Whoa, peanut, we ain't in public, yet."

You roll your eyes. He's been oddly insistent lately about when you use his rightful title. "C'mon, Soshiro-kun, before they start and we miss all the food!"

Your best friend loops your arm through his again and leads you out into the hallway, laughing when you try to pull your arm free only to fail as he tugs you more securely towards him. "Hey now, sugar cube, no runnin' away. We've gotta show up together or else people'll think they've got a chance."

You wrinkle your nose. "A chance at what?"

"They're already lucky bein' able to see you all dressed up," Soshiro continues as if he didn't hear you. "Maybe we should ditch the party."

"You're literally the Vice Captain of this base," you point out. "I think your absence would be noticed."

"What if we sneak out after dessert?"

"Why would we sneak out?"

Soshiro glances at you and pauses in front of the door leading into the ballroom. "Just 'cause I'm Vice Captain doesn't mean I'll forget to rescue you from all the socializin'."

"My hero," you joke, but several hours later finds you scanning the crowd uneasily for a head of violet hair.

The party is full of officers (easily distinguishable in their dress uniforms) and esteemed guests from various kaiju tech companies eager to promote their new products. You stuck to Soshiro's side for the most part, his hand firm and bracing at your lower back, but duty called and you ended up in a conversation with a tech mogul's son while Soshiro attended to his captain.

"Sorry, I know I'm not as good looking as the Vice Captain, but am I really boring you that badly?" the tech mogul — Takashi? Tadashi? — asks. You blink in surprise and return your attention to him, shifting on your heels.

"I apologize," you say, "it's just been a while…"

"It's been ten minutes," Takashi/Tadashi snorts. "If you don't mind me asking, how long have the two of you been together?"

Again? Why does everyone ask that? "We've known each other since childhood," you say. The man raises an eyebrow.

"Are you not… together, then?"

Something about his tone makes you bristle. "We've always been together," you say. You feel Soshiro before you see him, his hand resting warm on your lower back, just at the dip of your spine where it curves at your butt. This is a new spot for him to touch, a little lower than usual, but you lean into him anyway, seeking the comfort of your best friend. "Right, Vice Captain?"

"Who's askin'?" You startle a little at the subtle chill in his tone. Soshiro tucks you against his side with a hum as Tadashi introduces himself. "Nice to meet you, too," Soshiro grins. "Thanks for keepin' my cinnamon roll company."

Maybe it's your imagination, but did you hear a slight emphasis on "my"? And what's with dropping a nickname in public? Usually he's careful about referring to you by your surname when around strangers. The Third Division knows the two of you are close, but the ballroom is packed with people who have no idea about your relationship with the Vice Captain.

Tadashi doesn't seem concerned, but he does take a small step back. "Why of course, Vice Captain Hoshina," he says, "It was my privilege to be in the presence of such beauty."

You can feel Soshiro's arm tense as he slides it around your waist, but his tone is light. "Whoops, sorry, Takashi-san, duty calls. We'll be taking our leave now."

The crowd of pleasantly chattering officers and bigwigs parts easily as Soshiro guides you through towards the large banquet table full of small bites and snacks. You raise an eyebrow. "Wasn't his name Tadashi?"

"My bad," Soshiro says. You narrow your eyes at him and he laughs. "It's fine, my lil' blueberry. His father's the one in charge of their company and Captain Ashiro already made a good impression on him."

It doesn't surprise you that he already knows all of this — for all his joking, Soshiro's always been good at his job. What is surprising is that he was a little mean to the guy for no reason.

"Well, thanks for rescuing me," you say. "I was trying really hard not to yawn in his face."

Soshiro laughs and flicks your forehead fondly. "You ready to sneak outta this party, cupcake?"

"You won't get in trouble?" you ask, looking around doubtfully at the crowd. A few officers meet your eye and turn away quickly, which is weird. You reach up to rub at your forehead. "What about Captain Ashiro?"

"If we stay any longer, I'm gonna end up fightin' those guys from the Second Division," Soshiro says lightly, tilting his head towards the officers who just turned away from you. "They've been starin' at ya all night."

"No fighting," you say immediately. Soshiro snorts and crosses his arms over his chest. Your eyes skip over the way his shoulders bunch at the movement and you meet the eye of a female officer standing at the other end of the banquet table. Her face lights up and she moves towards the two of you, snagging two flutes of champagne along the way.

"Vice Captain Hoshina!" she says brightly, offering him the delicate glass. "I've been looking for you all night! It's been a while, hasn't it?"

You shift away, feeling suddenly like you're intruding on something private. Thankfully, the banquet table is a good distraction, and you move closer to it, wondering if you can find the dessert section while Soshiro catches up with this lady who's apparently an old friend. She must be from the Second Division. Maybe Soshiro met her when he visited their base to demonstrate and instruct on sword techniques?

You glance at her again. She's pretty, wearing the formal dress uniform of a female officer, though it looks like her long stockings aren't quite long enough, because the visible skin between her stockings and the bottom of her skirt is definitely against uniform regulations. She looks comfortable standing next to Soshiro, though, and the sight makes your insides twist strangely.

He's never mentioned her to you before. You remember greeting him after his visit to their base, accepting the snacks he brought back and tossing him your finished book filled with scribbled notes so he could take his turn reading it. Is he close with her? He must be, for her to look for him all night… right? It's not like you expect to know everything about Soshiro — of course he has his secrets and his own life.

And what if… what if he… and she… what if they were… together? You've never broached the topic of your love lives with each other, though it's never seemed to matter. You had your fair share of meaningless crushes during your time as an officer, but it was hard to care about pursuing anything romantic when you always had Soshiro.

Oh. Oh.

You are… an idiot. You feel so, so stupid. But Soshiro said he's a simple man in love — with you.

You're staring blindly at a platter of tiny cheesecakes when you feel someone approach, interrupting your train of thought. You glance up with a polite smile as one of the officers from the Second Division steps closer. "Those look delicious, don't they?"

"They do," you say. The officer looks nice enough — boyishly charming, in a way — but you find yourself glancing past him to scan the crowd for a head of violet hair.

Are you in love with Soshiro? Yes — of course you are — and maybe the semantics and nitty gritty details don't actually matter when you just feel right with him.

"Heya, pudding cup." Soshiro's touch burns along your lower back. "Time to head out?"

You twist towards him with a smile that makes his eyes widen. "I missed you."

Pink creeps up his neck as he grins back at you. "Yeah? Excuse me, officer, but I'll be takin' it from here."

The Second Division officer nods and mumbles some formalities as you leave with Soshiro, who doesn't take his hand off your back. The steady pressure of his fingers makes something curl in your gut. "What about the other Second Division officer? The one who brought you champagne?"

"Hm? Who?"

"Soshiro-kun…"

"She's just a friend," Soshiro says, snickering when you scrunch your nose at him. "Don't worry, bonbon, I've only got eyes for you."

The chatter and shuffling of the crowd fades as the two of you exit the ballroom and slip down a side hallway in the direction of your rooms. Soshiro drops his hand from your back, but you grab it before he can get too far, lacing your fingers together and peeking at the redness of his ears with a small smile. You turn together down another hallway, this one illuminated by squares of moonlight that do nothing to hide the clench of his jaw as he glances at you and squeezes your hand.

"Aren'tcha proud of me? No fighting."

You snort. "Thanks for not starting a brawl during a Defense Force party," you tease. "You're the best Vice Captain we could ever ask for."

"I'm not messin' around," he says. "I can't help it if I just wanna keep ya to myself."

"You don't have to worry about that," you say. You wonder if he can feel your pulse pounding in your wrist. "I'm all yours."
