Work Text:
- Establish some basic rules. The first thing you should do with your new roommate is to sit down and establish a short list of rules. This is a give-and-take conversation, so first list the most important things that each of you expects. Include how to divide the bills, who pays for what, policies regarding guests, cleaning schedule, and anything else you can think of.
“This isn’t fucking happening,” Kacchan growls, glaring at Izuku like he’s wondering if his Quirk can go as far as burning him with a simple look, knuckles white as he grips his huge red suitcase.
They’re both standing in the middle of the two-person room in the east wing of the residential building U.A. has adapted for its new boarding school system. The rooms are three times the size Izuku’s one in his mom’s apartment, and they all have their respective bathrooms, with a spacious wardrobe. He’d been pretty happy when he’d seen it, before he had a chance to check out who his roommate was.
“Uh.” Izuku gulps, shuffling his feet and not meeting the other boy’s eyes, swallowing hard, “I mean, we don’t have to interact much or anything, it’s just for sleeping, really, and that’s just -”
“Shut up , you fucking nerd,” Kacchan snaps at him. He sets his stuff on the bed near the window. “This is my side of the room, got it? Don’t you breathe near me, or I’ll fuck you up.”
“Okay,” Izuku agrees quickly, grabbing his yellow All Might back pack and biting his lip before saying, hesitant, “I’m just gonna, uh, go, now.”
“Good!”
He runs out of the room before Kacchan can give him another set of third degree burns, trying not to imagine the likely scenario of the other boy killing him in his sleep to ensure that Izuku doesn’t do something annoying, and realizes, dread pooling in the pit of his stomach, that maybe managing to convince his mom to let him come was a bad idea.
Ochako is rooming with Yaoyorozu, and they both look not too excited but fine with the arrangement. Iida shares with Yuuga, which, eh, looks challenging, but not life-threateningly, and Todoroki apparently rooms with Tokoyami. Izuku idly wonders if there’s going to be too much brood in that room for either of them to function, and almost grins despite his rapidly-rising pulse.
Because not only is he going to be sleeping meters away from his ex-childhood best friend, who can conjure up fire in his fingertips and holds a widely known grudge towards him, filled with anger issues and brimming with the need to take Izuku out (is Aizawa actively trying to kill him?). Oh no. To make matters worse, Izuku is going to see him shirtless .
He’s not sure how he’s going to survive this.
…
“Uh, Kacchan.”
“ What ?” the other boy snaps at him, pushing up his elbow to glare at him from a better angle from his bed, spiky blond hair falling into his eyes. He blows it away from his face, and puffs of smoke come out. Yikes.
“I, just, um. You’re using my part of the wardrobe, too. And,” he takes a deep breath, hoping he won’t get punched, letting it all blurt out, “Your stuff is all over the bathroom! And your dirty socks are on the windowseat!”
For a second, red eyes settle on his, neutral, and silence reigns in the room. Not a speck of dust moves out of place. A gust of wind hits the window, making him flinch. Izuku’s pretty sure Kacchan can hear his ragged breathing from the other side of the room.
And then it all goes to hell.
Kacchan lunges at him, leaping from his bed and landing on Izuku’s making a low noise in the back of his throat, fists first, grabbing hold of Izuku’s shirt collar and throwing him on the bed, placing each leg at either side of his hips, and hisses, “Are you fucking kidding me?”
“Sorry, sorry, sorry!” Izuku whimpers, trying to get out of his hold and wishing that All Might’s training had covered being immobilized under a much stronger guy who’s pissed at him, “I won’t do it again, sorry!”
Regardless, he walks into the dining hall with bruises all over his shoulders and feeling more beaten up than when he’d gone up against the Hero Killer, hobbling until he sits in their usual table, staring sombrely at his plate. He absently notes that Todoroki and Tokoyami seem to be locked in a brooding contest, checking to see who can hold that pouty “I don’t want any friends , I am one with The Night, and my Tragic Past haunts me” look for the maximum time.
Izuku groans and buries his face in his hands, accidentally soaking his sleeve with soup. Great.
“There, there,” Ochako soothes, patting his back softly, “You can always request a transfer?”
“No,” he moans, “Aizawa told us that the room configurations were final, and if I cause any trouble or complain my mom will know, and that’s a bye-bye to Hero School.”
“Rotten luck,” the girl murmurs sympathetically, “Yaoyorozu and I played cards yesterday. Maybe bonding exercises would help?”
Right when Izuku’s opening his mouth to reply, Iida sits down next to him. There is a clean circle cut in his uniform, letting everyone see his abdomen. He glares down at his plate and angrily attacks the soup (which Izuku didn’t even know was possible).
“Don’t ask,” he says between gritted teeth, “Laser Boy and I are mortal enemies now.”
Ochako and him share a glance that clearly says “Uh-oh, trouble is brewing, we must make Yuuga pay for his evil deeds”. At least, that’s what Izuku’s pretty sure it means.
“Well,” he tries, looking at Iida from the corner of his eye, “At least you didn’t get held down on the bed by your roommate.”
“What?” he asks, bewildered, when both of his friend send him flabbergasted expressions and Mineta spits out his juice from the other table, “I’m telling the truth!”
…
The next day, Kacchan turns on the cold water while Izuku is showering, resulting in a screaming match that the whole floor gets involved in, and soap bars starts flying everywhere, while Mineta throws his purple balls so that people can grab onto them and not slip on the wet floor, earning a “You’re not that bad, dude,” from Kirishima, which is a complete lie. Momo makes sure to lecture that thought out from him. Aizawa punishes them all by making them run laps for an hour the next morning.
Two days later, Izuku retaliates by lowering the thermostat until Kacchan can’t summon fire to burn his clothes, and Iida appears in the doorway holding a flag and shouting, “JUSTICE FOR CLOTHES! NO MORE DESTRUCTION OF FABRIC! WE MUST FIGHT THIS STRIKE AGAINST THE TEXTILE INDUSTRY, COMRADES!”
Kacchan rips the thermostat from the wall with his fire cannons and burns the flag, half of Izuku’s wardrobe, and his bed.
Aizawa doesn’t even bother with punishment, just makes All Might frown at them disapprovingly for a few minutes. Izuku’s stuck replacing the bed because he “provoked him”, and winds up sleeping in his desk chair for two days while the furniture company brings him a new one.
But eventually, when a week has gone by and their room resembles a war room more than two high schooler’s living space, after Todoroki has been called five times to freeze whatever Kacchan set on fire and Yaoyorozu has had to Create all the stuff Izuku broke with his accidental super strength, long after the Microwave Disaster of Epic Proportions, Izuku sits on the bed, looks at Kacchan, takes a deep breath, and says, “Okay, this isn’t working.”
“Really?” Kacchan raises a sarcastic eyebrow (which, yeah, Izuku knows eyebrows aren’t sarcastic, but Kacchan’s just are , okay?), “Wow, nerd, you’re a fucking genius. I wonder how you realized that.”
“Kacchan,” Izuku tries, pleading, “I don’t want to be kicked out of school, and I think you don’t want to, either. So we’ve gotta lay down some ground rules.”
That makes the other boy snort, “Rules? No, thank you.”
“ Please ,” Izuku insists, looking up to meet angry red eyes, “Just, no messy stuff everywhere, we divide stuff equally, we don’t put replace toothpaste with glue,” Kacchan smirks smugly and chuckles, “and just try to stay out of each other’s way. Maybe we can write down shower times.”
“Yeah, right. What’s the alternative?”
Izuku lets a smile draw across his face, “Bonding exercises, as suggested by Ochako. I have Monopoly and Uno in my bag.”
Kacchan narrows his eyes and scoffs, “That’s not bonding, that’s called ‘being humiliatingly defeated at board games’.”
Somehow, that makes him snort, “I’m pretty good at Monopoly, you know. I figure I could beat you one or three times.”
“Yeah, in your fucking dreams , nerd. Fucking nerds like you have no sense of strategy, you know. Bring it on.”
Izuku wins three times out of three. Kacchan burns the board and throws the box out of the window. In his anger, he sets Izuku’s bed on fire again and manages to take out his duvet before Todoroki freezes it. He’s supposed to feel disappointed and irritated, like the roommate situation is going to continue to suck, but something about the other boy sitting there and rolling the dice, scoffing and getting Regular Person Level irritated when he screwed up, makes his heart flutter in a very embarrassing way.
Well, at least he didn’t burn the whole bed this time.
…
“No.”
“But you didn’t even -!”
“I said ,” Kacchan crosses his arms over his chest, “No.”
“But look at it!” Izuku pleads, gesturing at the puppy in his arms, melting when it lets out a little yelp and bumps his head against his stomach, “It just wants love , Kacchan!”
“Well, it’s not going to get it here, nerd,” the boy declares, “And anyway, pets are against regulations, and you ’re the goody-two-shoes in this room, so fuck off.”
“Poor thing,” Izuku coos at him, petting it carefully, “How can you say those things, Kacchan?”
His roommate finally looks at him, glaring, and opens his mouth to shout more abuse, probably, when his eyes land on the brown labrador puppy, lifting its tiny paw to crawl up Izuku’s chest. His eyes narrow, and he glares at Izuku.
“Ugh,” Kacchan says finally, wrenching his gaze away, “Go and ask the Eraserdick, then. And if it shits on the bed I’m going to burn it!”
“You’re so nice, Kacchan!” Izuku beams at him, and runs towards the office. All Might’s, of course. No way in hell the Homeroom teacher is going to let him keep it. But a mellow hero with a weakness for strays? He’s got a pretty good chance.
…
The puppy stays.
Kacchan names it “Exploding Cat of Doom”.
Izuku just calls him Totoma.
…
“Deku!” Kacchan growls, and Izuku groans, burying himself in blankets and turning away from the noise, “Come on , nerd, we’ve got class!”
“Too...sleepy…” Izuku mumbles, “G’away.”
He got to their room late last night, after being stranded in the infirmary for over two hours because of the latest fighting exercise that they had done that afternoon, and all of his body aches . His left arm is throbbing in its entirety, and he’s pretty sure that he got a nosebleed in the middle of the night. Izuku just wants to sleep .
“Ah, fuck,” his roommate curses, “If you don’t get your lazy ass out of bed Aizawa will just make me come here anyway, so save us both a trip and get up, you nerd.”
“It huuuuuurts ,” Izuku whimpers, clutching the duvet and struggling as Kacchan tries to wrench it away, “Noooooooooo, lemme sleeeeep .”
“You’re even more annoying when sleep deprived,” Kacchan scowls, “How am I going to deal with you?”
“Hmmm...chocolate,” Izuku mumbles, feeling his eyelids close, “Kacchan could be nice.”
Totoma sneaks his way under the covers, and he cuddles it, letting out a soft sigh and snuggling into his fur. Everything feels so heavy…
When he wakes up, it’s three hours later and no one has shown up banging on his door.
There’s a cup of hot chocolate kept steaming by a small flickering flame at the bottom of the cup, and a note right next to it, Don’t be fucking nerd and come to class before Eraserdick busts your ass out of here. Or, you know, don’t come, and let me have the room all to myself.
-The Exploding Fire Badass
Izuku smiles, almost without meaning to, and puts the note in his drawer, stretching lazily and petting Totoma before getting dressed.
…
Izuku’s putting his pants on, biting his lower lip and wincing about how awkward jeans on wet skin are, when the door to the bathroom bursts open.
“Uh,” Izuku says, because he’s in his boxers .
“Uh,” Kacchan replies, looking suspiciously red and very pointedly Not Looking at anything, “I’ll just, er,” he clears his throat and hisses, “Put some clothes on, you fucking nerd! Save your troubling exhibitionist tendencies for that weird floaty chick! Exploding Cat of Doom is young and impressionable!”
He slams the door and leaves Izuku standing there, one leg frozen mid-air, feeling like his heart is about to jump out of his chest. Was Kacchan...embarrassed? He feels kind of sick and kind of happy all at once, like he’s going to throw up but for a good reason, like eating way too many sushi rolls, and he can’t help but wonder what Kacchan thought about him. Does he still look skinny and lanky? He knows that All Might’s training and U.A.’s physical programme have helped a lot, but he was never buffy to begin with and -
Izuku loses his balance and falls on his face on the bathroom floor, groaning. He’s going to be late for dinner.
…
“Um,” Tooro hesitates, and Izuku wishes he could see her face to guess what she’s asking about. She clears her throat, and then blurts out, “Is it true you’ve got a tattoo on your chest?”
“ Kacchan !”
…
“Eh, Deku,” Ochako says uneasily, “Bakugou is glaring at you.”
Izuku looks up from his homework, glancing around until he catches sight of Kacchan, staring at him, and the small silver of worry melts away, “Ah, no, that’s just his Nice Glare. That just means he’s grateful I did his laundry but doesn’t want to admit it. Usually followed by me finding hot chocolate somewhere and Kacchan refusing to acknowledge he brought it from the kitchens.”
Ochako stares at him, “ Dude.”
“Look, it’s right here,” Izuku bites his lip and searches until he finds what he’s looking for. Satisfied, he makes a small noise and sets his notebook Kacchan No.3 on his desk and quickly flips to the end, until he finds the page that’s marked by a small drawing of Totoma, “See? The Many Faces of Kacchan . I thought it’d be useful to learn how to interpret his frowns, seeing as we’re living together-” (“That sounds so wrong,” Iida whispers,) “- and so I kept chasing him with a camera until i got them all.” He points to No. 12, The Nice Glare , “Check it out.”
Ochako looks him up and down and says, “You need help, Deku.”
“I keep telling him,” sighs Kacchan from the desk near him, “Can’t believe the kid is such a fucking nerd. Stop stalking me and take your girlfriend out properly.”
“She’s not my girlfriend!” Izuku hisses, closing the notebook and hoping he isn’t blushing as much as he seems to.
“You don’t have to sound so scandalized,” Ochako mutters, and looks back to her textbook.
“Sure,” Kacchan sneers at him, and burns his pencil with a flick of his fingers.
…
Exam season creeps on Izuku before he notices, and then it’s suddenly time for cramming and studying until his eyeballs fall off. U.A. has a library with tons of places for quiet, relaxing study...except this is a hero school, and the library is usually filled with people shouting and random bursts of Quirks that make concentration more impossible than the off chance that Todoroki smiles at anyone.
So Izuku gathers all of his textbooks, tells Iida and Ochako that they’re not to bother him, explains to All Might that he’s going to be too busy to continue with personal training these next weeks, makes his mom take care of Totoma for a while, and locks himself in his room.
Locks himself. In his room. With Kacchan.
Yeah, great idea.
Somehow, the first day of studying, they don’t cross paths, because Kacchan can be kind of arrogant sometimes, without meaning to, and doesn’t really take studying that seriously. But on Tuesday, shit goes down .
“Stop muttering !” Kacchan hisses, and throws one of the pillows at his head. Izuku manages to duck in time, but hits himself with the edge of his desk, wincing and rubbing the back of his head, “It’s making me go fucking crazy!”
“I can’t help it!” Izuku mumbles, feeling guilty, “I usually study alone, so one was bothered about it before.”
“I’m going to go to the Common Room,” Kacchan declares, grabbing his stuff and sulking out of the door, slamming it for dramatic effect. Izuku sighs and emphatically does not pout because Kacchan left. He does not .
Ten minutes later, Kacchan is back, one of Mineta’s balls stuck to his bag, and frost on his clothes. He glowers at him and growls, “Shut up,” before sitting down at his desk again and continuing studying.
The silence is so awkward it’s painful .
“Um, Kacchan?”
“Yes?” the other boy asks curtly.
“What are you studying? I’m doing maths.”
Kacchan bangs his head against his desk, “Can you please just concentrate? Not all of us are fucking nerds that get everything immediately, you know.”
Right after he says it, the boy freezes, and Izuku stares at him.
“N-not like I don’t, you know!” Kacchan adds quickly, color rising to his cheeks, “I’m much smarter than you, fuck off, okay?! Just shut up so I don’t have to tolerate you!”
“Hey,” Izuku tries, setting down his books and swinging his chair so that he’s facing his roommate, “Do you want to study together?”
“No! Where’d you get that stupid idea, fuckhead?”
“I could use some help with my English homework,” Izuku lies, because anyone can see that Kacchan’s struggling and refusing to admit it. “And I’m sure you’re a great tutor, oh mighty Kacchan.”
Almost like it sneaks up on him, the corners of the other boy’s lips curl up, and he rolls his eyes and grits out, “ Fine . But only because I feel sorry for you, nerd.”
“Of course,” he agrees easily, and grabs hold of the other’s desk to pull himself to Kacchan’s side, swallowing a bit at how close they are. He glances down at his notebook, and frowns, “You’re studying Latin? I didn’t know you were in Latin class.”
“Well, I am ,” Kacchan mutters under his breath, and covers the pages with his hands, cheeks going pink, “I like languages, okay? Even dead ones. Shut up.”
“I think it’s cool,” Izuku blurts out, “And-and you’re a language nerd. So, there.”
Red eyes glare at him, Latin forgotten, “Who you calling nerd, nerd ?”
Kacchan’s leaning into him, his left elbow propped on the arm of Izuku’s chair, and he smells like that ugly black bottle of sports shower gel that he always leaves around in the shower, and somehow that makes Izuku’s breath escape his lungs, and he feels terribly, terribly small. His heart’s pounding, and he’s pretty sure he’s blushing. If he looks down, he’ll see down the collar of Kacchan’s t-shirt.
“I-I’m n-not -” he stutters, moving his leg up to get a little away from the other boy and maybe get some air, but he accidentally pushes Kacchan’s chair, and he yelps and loses his balance, falling squarely on top of Izuku and making their desk chair topple to the floor. Izuku hits his shoulder and hisses, looking up and -
Kacchan’s laying on his chest, rough and callused fingers holding his sides almost painfully tight, as if he’s still falling and clinging to Izuku is the only thing that can keep him stable. His forehead is pressed against Izuku’s stomach, warm, and his legs are settled between Izuku’s, beltbuckle digging into his pelvis.
“K-Kacchan?” he whispers, almost terrified that he’ll brush it off, that he’ll shout at him, that this isn’t what he’s thinking, that -
And then, suddenly, terrifyingly, exhilaratingly, Kacchan’s lips are on his.
They’re chapped, and feel a little warmer than his, and they taste (surprisingly) like sugar and sweat mixed together, which shouldn’t work but it does , and Izuku makes a small noise of pleased surprise, hand instinctively going up to bury itself in unruly blond hair. He senses a tongue prodding furiously at his lips, and he opens his mouth instinctively and -
Kacchan’s running out of the room.
Izuku’s just lying there on the ground, eyes wide, fingertips to his bottom lip, feeling his heart race, and he doesn’t know whether to go after him or hide under his duvet or drink fifty bottles of orange juice so he’ll die of liquid intake.
“Deku?” his head snaps towards the door, that’s still open from when Kacchan almost blasted the thing off its hinges, but it’s just Ochako, looking a bit uneasy, “Why are you on the floor? Anyway, I know you told us not to bother you, but -”
“Ochako,” he cuts her off, and he must sound wrecked, because she actually stops short and blinks at him, cocking her head to one side, “Is it possible that I just hallucinated the last few minutes? You room with Yaoyorozu, right? Can she make a machine that erases memories? Oh, man, that would be really useful right now.”
Ochako bites her lip, thinks for a second, and then declares, “I’m getting Iida.”
…
Izuku ends up blabbering about it for thirty minutes while Iida and Ochako buy him ice cream and pat his back awkwardly, feeling like an idiot for actually starting to cry halfway through and sniffling noisily. The other boy shares a glance with Ochako, and they both unanimously decide that he deserves some pampering.
They buy him another All Might poster for his room, because they’re great friends, dammit, and no , he didn’t tear up, Iida, clean your glasses; and get him the latest issue from his favorite manga. The cashier looks very unimpressed at the miserable teenager lounging in his shop.
Eventually, though, Iida makes a tactical retreat, and the only one brave enough to stay is Ochako, who sits next to him and asks, very gently, “Deku, did you want him to do that?”
“I-I-I don’t know,” Izuku mumbles, wringing his hands togethers and not meeting her eyes, “I mean, it wasn’t unpleasant , or anything. I just, I don’t know.”
It sounds lame. Oh god, it sounds so lame.
He’s pretty sure he’s managing to have an even more emotionally stunted conversation that what must go on in room Todoroki-Tokoyami (oh, idea time: the double T room) every day. For a second, the image of those two boys kissing gets in his head and - no . No, he’s not going there.
“I think you liked it, Deku,” Ochako tells him softly, touching his hair fondly. It feels nice, comforting, but nothing like the trail of blazing fire that Kacchan’s hands sparked, “I think you’re just a bit shocked now, is all.”
“Does this mean-” he takes a deep breath, “does this mean I’m gay , now?”
The girl shrugs, handing him another tissue, “Who cares? Just do whatever you want for now, okay, Deku? You may be a hero, but you’re still a teenager.”
“Ochako,” Izuku realizes, dread creeping up on him, “How am I going to sleep there tonight?”
She winks at him, “Well-”
Izuku throws the used tissues at her. She just makes them levitate and throws them back.
…
Kacchan is lazily sitting on his bed when he opens the door after dinner, highstrung and blushing (but just a little bit!), and he almost jumps when he sees him.
“Oh,” Kacchan growls, closing the textbook he was looking at, cheeks definitely red, and lifts his chin up, almost as if daring him to say something, “It’s you .”
“Erm, yeah,” Izuku admits, caught off guard, “We are roommates, after all.”
“I know that!” Kacchan snaps, and little puffs of smoke come from the textbook. He glances at it, a little nervous.
“Great.”
“I know it’s great! I don’t need a fucking nerd to tell me!”
“Um, okay.”
“Just-!” Kacchan makes a frustrated noise in the back of his throat and stands up, waving his arms around, “You make me want to hit things! Lots of things! Many times!”
Izuku takes a step back, scratching the back of his neck and hoping that he survives the night, “Um, sorry? I don’t...mean to?”
“ Stop it!” the other boy shouts, and moves until he’s holding Izuku’s wrists, hands tightening around them, and he looks wild, like nothing’s holding him back this time, like he’s going to tear Izuku apart and no hero is going to save him, because -
Kacchan pulls , and Izuku stumbles awkwardly into his arms, arms going up to rest on the other’s boy’s chest, flushing immediately and trying not to meet his eyes, murmuring, “Just, er, let me -”
“I don’t know why I like you,” Kacchan chokes out. Izuku’s head snaps up, and he’s sure that he looks completely mental, eyes so big they could probably have their own gravitational field, mouth open, hands going immediately still. “I don’t know, god help me, you fucking nerd -”
Izuku kisses him, because fuck it, he’s fifteen and he’s pretty sure he just got a confession, so he’s going to go for it. He puts his arms behind Kacchan’s neck, a little shy but a little more turned on and kind of excited, and the other boy responds eagerly, hungrily, like he’s been waiting for this since the first day they got paired together in this heavenly room, hands going to rest at the small of his back, making Izuku hum contentedly, even drifting lower, which just makes him blush and cut the kiss to bury his head in the crook of Kacchan’s neck, feeling his heart race, panting even though they’ve barely done anything.
“I like you too,” he confesses, and he doesn’t think he’s imagining the way his roommate’s grip on him tightens.
“Don’t let it go to your head, nerd,” Kacchan mumbles, but he doesn’t sound as pissed as he usually does, so Izuku smiles and pecks his lips again, feeling almost giddy. “You’re still a pain in my ass.”
“That...acquire new meaning, in context,” he smirks, and feels the way Kacchan stiffens and groans.
“How did this happen to me? I hate the fucking world, I’m going to demand a refund.”
“You’re...not, are you?” Izuku asks, biting his lower lip, because he still can’t believe it entirely, “I mean...are we boyfriends now? Or are you just…?”
He pauses in the middle of his mini-breakdown, wrinkling his nose, “Hey, Kacchan, doesn’t it smell like -?”
Izuku takes one minute to take in his roommate’s panicked expression, red eyes wide, and the smoke coming from his hands, and the smell of burnt wood and -
“Oh my god , Kacchan!” Izuku gapes, taking a step back, “Did you just set fire to our room?!”
The bed is burning . It’s burning where Kacchan touched it when they moved a few steps back. Kacchan set fire to the bed . Again . For a moment, they both just kind of stand there, watching the duvet be consumed by small flickering flames that slowly get bigger, with that odd calm that comes with being a teenager and trusting that the adults will take care of everything.
And then -
“We have to put it out!” Izuku realizes, turning to stare at Kacchan, “Get Todoroki, right now !”
“He’s at home studying! Fuck, where’s that annoying popsicle when you need him?!”
“Oh my god!” Izuku breathes, a lump in his throat, “Oh my god, we’re going to die because I asked you out. This is awful.”
“Just get some fucking water from the toilet!”
“How am I going to carry it, though?!”
“Use something , I don’t fucking care! Use your fucking head, it’s empty enough of a brain as it is!”
“Don’t talk to me like that! That’s disrespectful, Kacchan!”
“We’re going to fucking burn to death, and you’re worried about manners ?!”
“I’m trying to have a healthy relationship!”
“It’s been all of ten seconds of this fucking relationship!”
“AAAhhh!” Izuku screeches, “I don’t want to die like this!”
“I hate you both,” Iida declares from the door, and sprays the tiny fire with a fire extinguisher. Oh, yeah. Because there’s a fire extinguisher. Pretty much everywhere near Todoroki and Kacchan. Yeah. That makes sense. “Please go and be useless somewhere else. Some of us are trying to study.”
Kacchan throws a fireball at him, and Izuku starts to scold him, because, “You can’t keep hurting people because they disagree with you, Kacchan!” until the other boy just makes a frustrated noise and kisses him.
…
“Oh my god,” Izuku whispers as Mineta and Yaoyorozu exchange some yen. She makes sure to wipe her hands clean afterwards.
“Hey, I was betting on next week, after exams,” the girl says defensively, crossing her arms over her chest, “I thought it was a very useful exercise for practicing reading people and their emotions and -”
“I woooooon ,” Mineta sing songs, “I wooooon the Bakugou-Midoriya pool!”
Kacchan burns the yen, and, for once, Izuku doesn’t shout at him for it.
He actually moves a little closer to him on the table, which makes Ochako giggle and Iida sigh, long-suffering.
…
“WOOOHOOO BAKUGOU, MAKE OUT WITH THE NERD!”
“...”
“...Oh. Okay, uh, I didn’t think you’d go for it.”
“...”
“...I’m just going to...go...now.”
…
“So, Kacchan,” Izuku starts, a bit uncertain.
“Hmm?” his boyfriend murmurs, hair brushing Izuku’s forehead. They’re lying on Kacchan’s bed, because Izuku’s is covered in stuff and he’s too lazy and warm to want to clear it all out, so right now he’s just using Kacchan as a pillow. Hmmm, he’s soft.
“My, uh, my mom wants to meet you.”
“...”
“Kacchan? Kacchan, is that okay? I just, I mentioned that we’re closer now, I didn’t tell her -”
“...”
“...is that-? Oh my god, Kacchan, are you burning the bed again ?! Todoroki! Todoroki !”
