Work Text:
Iida, ever since Kirishima and Bakugo became best friends, has constantly had to get after them for “public displays of affection”.
They are representing the hero course, after all. And they have to look respectable.
Especially in that UA uniform.
So, every time he sees them holding wrists, an arm slung around a shoulder, a big bear hug that Bakugo pretends not to like, Iida gives them his disapproving dad look.
“Kirishima, Bakugo. This is not the time or place.”
Kirishima would always toss him a sheepish smile, Bakugo an eye roll.
He understands that they are boyfriends, but that should be done not in the classroom—a place for learning.
However, it seems with every time he gets after them, it grows worse.
He walks into them holding hands in the classroom before the school day.
Iida is genuinely impressed by their punctuality, as Iida himself comes to school 30 minutes early and is always the first one there.
Bakugo is sitting backwards on his desk while Kirishima is talking animatedly on Midoriya’s.
Their hands come together absentmindedly, Bakugo looking down at their joined fingers with a small smile. Iida didn’t even know he was capable of a smile so soft.
Feeling his heart warm at the sight, he decides to let it go for the time being.
After all, school hadn’t started yet and they weren’t breaking any rules.
“Good morning, you two. I commend your early start to your day!” He says, as they are seemingly unaware of his presence.
“Oh! Ah—sorry Iida. Um, didn’t see you there, man.” Kirishima attempts to let his hand go from Bakugo’s, but his best friend glares.
“We’re early, four eyes. Can’t tell us shit.”
Iida nods, “Of course not, Bakugo. Carry on as you were.”
Bakugo looks taken back, glare faltering to amusement, before he turns back to Kirishima.
They seem to be lost in their own world, Bakugo listening intently to whatever Kirishima has to say.
Their hands never separated, not until Midoriya walked in and to his seat. “Hey, man! Here’s your desk!”
Midoriya looks down at their joined hands and sputters, his hand twitching like he’s aching to reach for one of his notebooks.
“Well, thanks for listening to me blab, Kats. See you after class, yeah?”
“Idiot, you weren’t fucking blabbing. And I’m gonna be in your damn eye view, what the hell do you mean after class?”
“Guess I’ll just miss you, man!” Kirishima laughs.
“You’re seriously moronic.” He scoffs with a smile, pink dusting his cheeks.
At lunch, Iida can’t help but smile at the sight of the two.
As he passes by their table with Sero and Denki, Kirishima tries to take a fruit off the small container Bakugo had in his hands.
“Back the hell off, Eij!”
“Aw come on, you know you wanna share some with your best friend, man.”
“Fuck off! Shit’s mine.”
Kirishima outright pouts, puppy dog eyes and all.
“Fucking hell, boulder brain. Just—here.”
Bakugo takes out a strawberry from the container, handing it to Kirishima.
“Don’t want your dumb dirty hands in my food, asshole.”
Kirishima doesn’t take it, however, simply holding his mouth open.
He waits, eyes in a smile.
Bakugo rolls his eyes, taking a second to calm himself before placing the fruit tenderly in his mouth with a tickled grin.
“Mmm! Sho yummy!” Kirishima says with a mouthful.
Bakugo’s cheeks heat even further at the sight, giving him another fruit right away.
The week goes on like that, Iida finding Bakugo and Kirishima early in the classroom.
He nods at them, getting an early start on his reading, while the two are lost in each other.
“Give me your arm.” Bakugo grunts.
“I mean, if I could take off my arm I would man, but—“
“You know what the hell I mean, you ass.”
Kirishima chuckles, “Sure! You still tired?”
Bakugo hums, going to rest on Kirishima’s offered arm.
“I slept pretty good last night, you know, cuddling with—“
“Eij!” Bakugo’s head shoots up, eyes wide.
“Aw, sorry, man. Kinda forgot we weren’t alone.” He whispers.
It isn’t until a week later that Iida finally, truly, feels like he’s invading on a moment.
“I just, I have a really big crush on you, Kats. And I understand if you don’t feel the same. But I can’t hold it in anymore. I’m sorry.”
Kirishima’s voice travels through the door.
“Why the hell are you apologizing, Eijiro?”
“Because, dude. I’m kinda like in love with you. It’s crazy. I know. I understand if you do—“
The room goes silent, and Iida peeks into the classroom door window, concerned.
But, he steps away, embarrassment growing as he sees Kirishima and Bakugo in a kiss.
Back in the classroom, Bakugo has his hands fisted in Kirishima’s tie. Kirishima’s hands are carding through Bakugou’s hair.
Their first kiss, where their crushes started. Their love.
If Iida developed a soft spot for the two, getting after them less and less during the school day, he’d never admit it. Though, he knows it’s true when Kirishima shows up to the common room one day, hands behind his back.
Bakugo is sitting on the common room sofa, waiting for him.
Iida had been there first, of course. He preferred doing his homework in public, as maybe he’d inspire a fellow student.
“Hey, Kats! Sorry I made you wait.”
“Whatever, dumbass. Where’s this special thing you wanted to give me?”
Iida tries not to look, he really does. But it’s hard not to, especially when they’re in his direct eye view.
Kirishima smiles, taking a bouquet of flowers from behind his back.
“Flowers, idiot? Huh.” Bakugo takes them with a blush, bringing them to his nose.
“It’s uh—got a card! You gotta read it.” Kirishima avoids his gaze, eyes on his feet instead.
Bakugo fishes around the bouquet until he finds it.
In Kirishima’s handwriting, the card says:
“I think you’re as pretty as a flower :) Be my boyfriend? <3 -Eij”
Bakugo lets out a laugh, so soft, so fond.
“Thought I already was kinda your damn boyfriend?” He teases.
“I mean! Yeah! But you deserve to be asked properly, you know?” Kirishima reasons.
“I love you so much, you know that?” Bakugo says.
“Hey! I love you too!”
“You gonna take me out on a date as official boyfriends now, Eij?”
“Of course! Wanna go get some dinner, babe?”
Bakugo snorts at the pet name, “How long have you been waiting to call me that?”
“Since the first day of school! You’re a total babe, babe !”
“Oh my god, Eij. Shut the hell up.” There’s no heat to his words, just an adoring smile.
Bakugo pulls Kirishima into a kiss, the redhead bent over to where he was sitting on the sofa.
They lose themselves again, and Iida finally steps away.
He finds himself slightly tickled at the fact that they were never boyfriends, just best friends. But, his heart warms once more at the fact that they couldn’t hold in their love for each other.
In the common room, Kirishima finds himself being pulled down to the sofa, flowers squished between him and Bakugo. “Kats, your—“
Bakugo places them gently on his side, coming to cup Kirishima’s cheeks. “I love you Eij, I really fucking mean it.”
“I know, I love you more, though.” Kirishima giggles.
“That’s crap. I love you more.”
Kirishima laughs once more, closing the space one last time before they head off to dinner.
In school the next day, Kirishima and Bakugo come to class hand in hand, Bakugo unable to hide the smile he has.
They’re later this time, students already in the classroom.
As the bell rings, Kirishima leads Bakugo to his desk with a smile.
“See you after class?”
Bakugo rolls his eyes, “See you after class, dumbass.”
Kirishima grins, grabbing his chin as he sits to place a kiss on his boyfriend’s pretty lips.
“Kiss you after class?” Kirishima asks.
“Go sit down before Aizawa gives you shit.” He blushes.
“Alright, see you later, babe!”
Kirishima’s heart swells at the sight of his boyfriend, unable to tear his eyes away as he holds his gorgeous smile.
Iida can’t help but smile either, shaking his head because he truly was becoming a softy.
Kirishima and Bakugo stay together for the whole of high school, getting married a year after they graduate.
And as they kiss in front of their families, old classmates, and several pro heros, the whole world falls away as if no one else is watching.
