Bakugou's eyes narrowed as the girl stumbled through her sentence, barely managing to spit the words out between her trembling lips. Part of him wanted to just cut her off before she finished, to send her packing and stop wasting his time, but he knew from experience that if he did, he'd end up wasting even more time listening to his classmates complain about him being rude.

“I'm not interested,” he said flatly, the moment she choked out her final word. “Thanks, I guess, but no.”

It didn't do anyone any good if he tried to soften the blow, he wasn't going to leave some random extra with false hope that he might come around one day if she waited long enough.

“O-Oh,” she swallowed hard, nodding faintly. “I u-understand. Thank you f-for l-listening.”

“You should go to class,” he pointed out, nodding toward the classroom clock. “You're gonna be late.”

“Y-Yes, thank you!”

With a little bow and watery eyes, she hurried from the room, and Bakugou prepared himself for the onslaught that was no doubt coming from his classmates.

“What was that, girl number twenty?” Kirishima teased, hoisting himself up to sit on the edge of Bakugou's desk. “You must love this holiday.”

“Worst fuckin' day of my life,” Bakugou scowled, shoving him away firmly. “Hate this sappy bullshit.”

“Uh-huh,” Kaminari chimed in, slinging an arm around his shoulders. “Must be a nightmare, Mister Popular.”

“Get off me, asshole.”

Even as he shrugged Kaminari off, he found his gaze drifting to a desk at the back of the classroom, littered with frilly pink cards and pretty little packages. Todoroki sat with the usual impassive expression on his face, stacking them up neatly to make room for his books and pens, but he seemed to feel the fiery red eyes turn his way. His gaze rose, mismatched eyes meeting Bakugou's, and then they were both quickly looking away again to distract themselves.

No one seemed to notice the short interaction between the pair. Bakugou didn't even pause to consider that anyone had paid attention to their brief acknowledgement of each other, but as the bell rang for class to start, a little purple brain began to run wild.

─────

Todoroki looked up when the light footsteps approached, surprised to see a much shorter figure approaching them in the hall. Bakugou's eyes narrowed, but Todoroki gave him a warning look, and he kept his mouth obediently shut.

“Hi Todoroki, Bakugou,” Mineta spoke up, feigning a confidence that his expression completely betrayed him on. “Seems like you've been having a good day.”

“What do you want, dweeb?” Bakugou scowled. “Spit it out and get out of my face.”

“I just couldn't help but notice that you guys were getting a lot of Valentine's gifts today, thought maybe there was some clever plan you'd come up with. So tell me, what's your secret?”

“Being pretty, apparently,” Todoroki shrugged, stuffing his hands in his pockets casually. “That's what they tell me, at least.”

“Not being a creep,” Bakugou snorted. “If you want attention from girls, stop being a pervy little cretin to them. They're human beings, you dumbass.”

“Oh come on, there must be something special you're doing!”

“Being hot?” Bakugou offered. “Try hitting the gym once in a while, and maybe buy a pair of stilts or something.”

“I came here for advice! I didn't come to be made fun of!”

“I gave you advice, take it or leave it and either way, get out of my damn face.”

Mineta huffed a little, but neither of the pair broke, and finally he conceded with a sigh.

“Fine, don't tell me,” he grumbled. “I'll find out some other way.”

“Good luck, shrimpy.”

As he stalked away in a huff, Todoroki glanced over at Bakugou again, surprised to see a hint of a pout in his expression. Most of their friends and classmates only saw the harder looks, the scowls and glares, but every so often the people closer to him managed to glimpse something a little softer.

“He's gonna be watching us,” Bakugou grumbled. “We're not gonna get away with shit for at least the next couple of days.”

“It's fine,” Todoroki shrugged. “We'll make it work, we always do.”

“Yeah, I guess.”

With the tiniest of smiles, Todoroki reached out, ruffling blond spikes and enjoying the way Bakugou spluttered and whined in response. He slapped Todoroki's hand away, but the motion was a lot more gentle than it could have been, without even a hint of explosion to make it truly lethal.

“Leave me alone, jerk,” he complained, cheeks flushed a pretty shade of pink. “I hate you.”

“Uh-huh. See you after class.”

“Shut up,” Bakugou barked, storming away down the empty hall. “See you later, asshole.”

“Looking forward to it.”

Mineta knew he was overstepping when he took the phone, but when he'd seen it just lying unattended on a desk, he couldn't resist. His hand was on it before he even paused to think twice, slipping it into his pocket as they all headed out for lunch, and he ducked off to the bathrooms while everyone else was filing into the cafeteria. If all went to plan, he could sneak a peek at the messages and get it back before lunch was over, no one would ever be any the wiser.

The first issue was the passcode. He was shocked enough that Bakugou would leave his phone unattended for even half a second, there was no way it would be sans passcode too. Bakugou wasn't a sentimental guy, so right off the bat he saw no reason to start running through dates. Maybe a word? But no, Bakugou would probably just pick some random number and memorise it so no one could figure it out so easily. He was going to have to go for plan b.

He dug out his own cellphone, opening his most recent text conversation and typing out a quick message.

No questions asked: Do you know Bakugou's phone passcode?

There was only a brief pause before Kaminari replied, and his hopes shot to the roof when he saw the words inside.

That depends, are you prepared for the consequences when he finds out?

Yes.

0111

It was a strangely simple number, Mineta had expected something a little more complex, but there was no time to stress over that. He was on a mission, he had to get in and get out before Bakugou could notice it was gone – he trusted Kaminari not to spit it out unprovoked, but he wouldn't put it past the guy to drop hints if Bakugou started searching for the device.

He opened the texts first, surprised to find an empty inbox waiting for him – had he anticipated this? Was he already clearing his messages to keep intruders out? The guy was one step ahead after all, Mineta should have known.

A little red number on a folder of icons piqued his interest, and his lips stretched into a wide grin when he found the familiar green app inside. Bakugou wasn't very social, at least when his friends weren't forcing him to be, so he'd kind of assumed there wouldn't be any social media on the phone. And yet, here he was, opening the chat app to find a world of conversations.

It was Midoriya who had sent the message, Mineta should really do something to thank him. Even though he didn't do it on purpose, and frankly had no idea he'd helped at all, he was the driving force that had led Mineta to the app, and for that, he was grateful.

He bypassed that message entirely, though, and went straight to a red and white icon a little further down the list. It took a moment to load, the thread exploding with thousands of messages, and for a moment Mineta could only stare. The pair seemed to hate each other in class – maybe be tentative teammates on occasion since their remedial classes together, but he wasn't sure he'd ever have called them friends.

As he scrolled back through the messages, he began to realise exactly how deep the plan ran. There were vague words, hints he couldn't quite decipher, arrangements for secret meetings – they had been plotting for weeks. And all to pull a bunch of girls for Valentine's Day? That was something Mineta would have done, he never thought his classmates were the same way.

Or maybe, just maybe, the plan ran a little deeper. Maybe it wasn't about Valentine's Day at all, maybe it was a long play. That was why they'd made so many rejections earlier in the day, why Todoroki had calmly thanked them for their gifts but not made any further plans, why Bakugou had heard them out and then sent them away without a second thought. It was like the ultimate form of playing hard to get! How had he never thought of it?!

Well, he didn't exactly get a lot of confessions to reject, but that was beside the point.

Satisfied with his research, he locked the phone again, sneaking back into the classroom to return it to the empty desk. He crept past a sleeping Aizawa successfully, and then he was breathing a sigh of relief, finally heading to the cafeteria to get some food.

The secret meetings had happened every day for the past week, if his quick scrolling was to be believed. There was no reason to think that night would be any different – they would have to reconvene to discuss the day's successes, after all. He would lie low in the common area until both of the guys retreated for the night, then he would sneak upstairs to spy on their meeting.

Simple, what could possibly go wrong?

─────

Bakugou slammed pots and pans as he finished serving up food, his tray laden with bowls. In one, a mountain of thin noodles mixed with onions, a much smaller bowl of dipping sauce on the side that he'd spent a solid ten minutes getting perfect; in the next, a pile of beef stirfry with a rainbow of colourful vegetables; and finally, under a little cover to keep it clean and cold, a little sponge cake covered in cream and strawberries. He'd spent far too long on the food, his friends had to be getting suspicious, but no one bothered him as he shut himself in the elevator.

Normally, he would get off at the fourth floor, locking himself in his room to escape the madness. Tonight was different, though – he'd made plans in the empty hall before class began, with his cheeks burning red despite how he willed them to cut it out. Todoroki had flashed his rare little smile when Bakugou barked out the demand, and his hand had been warm on Bakugou's shoulder when he laid it there lightly.

“Yeah, I'm looking forward to it,” he'd said softly.

And then they'd been interrupted by the stupid, purple, pain in the ass that was their miniscule classmate. Ugh.

He kicked at the door when he arrived, his hands too full to open it himself – it was probably the closest he'd ever come to actually knocking, which he suspected was why the face that answered was so uncharacteristically surprised. He stepped aside just in time for Bakugou to not elbow him out of the way himself, watching silently as Bakugou laid the dishes out on his low table.

“You cooked,” he said quietly, and Bakugou felt himself blush. “You made all of this yourself?”

“Shut up,” Bakugou huffed. “Close the damn door.”

Todoroki closed it obediently, locking it behind them, and after a short pause he sat down at Bakugou's side, rather than across the table. Bakugou could feel his cheeks lighting up again, but he didn't bother to say anything, just shifted over to make room and handed Todoroki a pair of shiny black chopsticks.

“You should eat the stir-fry first while it's hot,” he instructed, dragging the bowl between them. “The soba can wait.”

“You made me soba.”

“Obviously, you damn imbecile. Are you gonna eat the food or not?”

“Thanks, Katsuki.”

He leaned in, planting a tiny kiss on Bakugou's cheek, and Bakugou yelled his frustrations into the wind. Todoroki just smiled and watched him have his little breakdown, letting Bakugou squirm and tear at his hair frantically.

“You liked that?” Todoroki teased. “I can do it again.”

“Shut the hell up, you damn idiot! Ugh! You're so embarrassing! Shit!”

Todoroki reached out, his hand tangling lightly in Bakugou's hair, holding him still as he leaned in for another quick kiss on the cheek.

“Fuck you!” Bakugou hissed, falling still all the same. “You're such a cheesy fuck!”

“I thought you liked it.”

“Shut up!”

“So you do like it?”

“Shut up.”

“You made me dinner for Valentine's Day, isn't that far cheesier than a little kiss?”

“Fuck you, I'm taking the food back to my own damn room!”

Todoroki grinned, and Bakugou softened instantly, enthralled by the shining smile that lit up his scarred face.

“Fuck you,” he repeated once more, leaning in and snatching Todoroki's lips in a much less gentle grip. “Worst boyfriend ever.”

He looked up briefly when he heard footsteps passing the room, pausing to see if they stopped and interrupted – maybe he'd been too loud after all – but when no knock came, he returned to the much more enticing task at hand – a less cheesy, and much more familiar, kiss with his idiot boyfriend.

At the end of the hall, unseen, Mineta thumped desperately at an elevator button.

─────

Even Todoroki, ever the imperceptive about emotions and all that nonsense, had noticed that Mineta seemed out of sorts. Ever since he'd come begging for information about their Valentine's plot – stupid as the assumption was – he'd seemed weirdly antsy, always twitching and stuttering when Todoroki and Bakugou were around.

“He's probably coming up with some stupid plot to make us spill the beans,” Bakugou shrugged, reaching to add more salad to Todoroki's plate from the lunch buffet. “Eat your vegetables, asshole. He just wants to find out why girls like us or whatever.”

“Why do girls like us?” Todoroki pondered.

“You're joking, right? Look in a damn mirror.”

“Because I'm pretty?” he asked, catching Bakugou smirk before he looked away. “You say it a lot, but I didn't think it was that simple.”

“It is.”

“And you?”

“What, you don't think I'm pretty?” Bakugou snorted, taking an extra helping of chicken as they moved down the line. “Protein. I'm pretty sure they like me for my looks too, it's certainly not my personality.”

“I like your personality.”

“Shut up, nerd.”

Todoroki took extra chicken for himself, too, under Bakugou's watchful eye, and then they were off. They parted ways with a short nod, Bakugou heading over to his rowdy squad of friends while Todoroki joined his much quieter group across the room.

“Was Kacchan giving you a hard time?” Midoriya asked, the moment he sat down. “He's really picky.”

“It's okay,” Todoroki smiled, drowning his salad in dressing now that Bakugou wasn't around to watch. “I guess he considers me a friend, if he's gonna fuss about my eating habits.”

“It's like he's the class Mom,” Uraraka giggled. “Even if he's a bit of a rough parent at times.”

“His mother is too,” Midoriya smiled. “That's probably the only image of motherhood that he has.”

“Well, he certainly seems to have toned down the anger and violence,” Iida mused. “That's certainly a positive for our class life.”

Todoroki nodded, eyes drifting toward the noisy table in the corner as he took a bite of chicken salad, watching as they argued and teased and shoved each other around. They were a rowdy bunch, that was for sure, but even Todoroki could see the affection in their words and gestures. They might have a weird way of showing it, but that table was just as close as his own.

“Todoroki is making goo-goo eyes again,” Uraraka giggled. “When are you going to 'fess up?”

“Kacchan wouldn't mind,” Midoriya added. “He might think it was weird, but he's not gonna be angry or anything.”

“I don't know what you're talking about,” Todoroki said flatly, taking a sip from his milk carton. “I don't even understand what you're saying.”

“Uh-huh,” Uraraka humoured him, smiling to herself. “For what it's worth, I think you'd make a cute couple.”

“Me and who?”

“Don't act like you don't know.”

Todoroki shrugged, returning to his food, but he couldn't help but cringe when Iida spoke up far too loudly for his liking.

“You know, confessing your love is a brave thing to do! Opening yourself up to the possibility of rejection for the potential of something more, it's almost heroic, in a way!”

He heard snickers from the nearby tables, and his cheeks felt slightly warmer as he ducked his head to quickly cut more chicken.

“Wait until you're ready, there's no point in rushing it,” Midoriya said with a smile, ever the voice of reason – well, except when he was breaking his body to fight a villain. “He'll wait.”

“Bakugou isn't exactly the patient type,” Uraraka argued. “Surely he'll just break and start yelling about it if Todoroki takes too long?”

“Nah, he'd think breaking first is losing. He'll wait as long as it takes to win.”

“I don't know what you're talking about,” Todoroki said again, sipping at his milk as if it were a cup of fancy tea. “Neither of you make a word of sense.”

“Keep telling yourself that, buddy,” Uraraka said fondly, patting him on the shoulder. “We'll wait too. Just give us a call when you're ready, and we'll talk it out with you, figure out how to tell him.”

“Whatever you say.”

When he glanced over toward Bakugou's table again, he instead caught the eye of a little purple lump at the next table over. The dark eyes darted away in a hurry, avoiding Todoroki's gaze, and he sighed faintly to himself. No matter what Bakugou said, he was concerned about what the guy was planning – he'd kind of hoped Bakugou might offer to intimidate him, rather than brush it off as no big deal. When Mineta sneaked a peek back his direction, Todoroki narrowed his eyes slightly, satisfied when Mineta nearly jumped out of his skin.

Yep, definitely plotting.

─────

Mineta had done his best to avoid the pair, after the terrifying words he'd overheard in the dorms, but he'd known it was only a matter of time before he got stuck. He didn't, of course, expect it to end so soon. He'd hung back after training in the afternoon, waited for them to be out of the changing rooms before he made his way in to grab his clothes, but instead he heard the familiar voices still lingering by the lockers.

“You been a good boy today?” Bakugou teased.

“Mmm, not particularly,” Todoroki answered, a hint of a smirk in his own voice. “You might even say I've been bad.”

“Oh no, we can't have that, can we?”

A little squeak escaped Mineta's lungs, and suddenly two heads were turning to look at him, teasing smiles fading immediately into frowns.

“You didn't see shit,” Bakugou informed him, stepping away from Todoroki to loom over Mineta's short stature. “Got it, Pipsqueak?”

“Got it!” he shuddered. “S-So you weren't m-meeting to figure out how to get Valentines?”

“Haaah? Fuckin' of course not,” Bakugou growled, Mineta shrinking even further under his scowl. “Who the hell do you think I am? You think I give a shit about some shitty cards and chocolates from random extras?”

“N-No, I guess not.”

“So get your puny ass out of here and keep your stupid mouth shut, got it?”

“G-Got it.”

He grabbed his things and backed out in a hurry, breathing hard as he escaped from the tense room. He desperately wanted to tell someone, to share his misery, but the look in Bakugou's eyes was burned into his memory – he didn't want to see the wrath that would come his way if he dared to betray his promise.

Back in the changing rooms, Bakugou ran his fingers through strands of silky hair, freshly washed in the nearby showers after a long, sweaty training. He liked seeing the colours mix together, dragging white over into the red with gentle fingers, a soft look on his face that he would never admit to wearing.

“Kiss?” Todoroki asked, his voice barely more than a whisper.

“Since you asked so nicely.”

He could never resist Todoroki's little pout, even though he knew it was usually just put on to get what he wanted. He leaned in, bringing their lips together gently, and Todoroki's arm wrapped around his neck to hold him close. Smirking, Bakugou reached down, gripping a thick thigh and bringing it up to wrap around his waist.

Todoroki had come to enjoy the feeling of relying on Bakugou, having someone who took care of him so readily and without question. He suspected Bakugou enjoyed it too, liked to feel in charge and in control, liked to give just as much as Todoroki liked to receive.

Todoroki gripped tightly with his leg, wrapping the long limb around Bakugou's slim waist, and when the warm hands slipped under his thighs, he shifted the other to match. Bakugou didn't even seem to notice the extra weight bearing down on him, despite that Todoroki probably weighed more than he did, and Todoroki felt his pants getting tighter in the crotch.

“You like that, huh?” Bakugou teased, nipping at the pale skin of Todoroki's neck. “You wanna get off right here, where anyone could walk in and see you all needy and whining?”

Todoroki nodded frantically, and Bakugou smiled a little wider, stepping in to brace Todoroki against the cold wall. He shifted his grip, using the wall to free up one of his hands and palm at a firm bulge.

“Feel good, baby boy?” he hummed into Todoroki's neck, slowly trailing his fingertips up to the fly of his pants, Todoroki nodding desperately. “I'll take good care of you.”

With shaky hands, Todoroki cupped Bakugou's cheeks, dragging him up for a long, messy kiss. Bakugou allowed it, nipping at a soft lip before he thrust his tongue through, swallowing Todoroki's low moan. Their first few experiences together had been oddly quiet, Todoroki practically unresponsive despite insisting he enjoyed it, so to get those little noises out of him with so little coaxing made them music to Bakugou's ears.

He kept their lips together, tongues mingling as he slid the zip down, lazily freeing Todoroki's smooth skin just an inch at a time. Todoroki's hand shifted, yanking his underwear down to his thighs, and Bakugou broke their kiss to look down. His breath hitched when he saw the swollen cock already leaking fluid, and Todoroki smiled as he nuzzled into Bakugou's hair.

“Take care of me?”

“Course I will.”

He dug a bottle of lube from his pocket, slicking up his fingers, and Todoroki moaned when he felt them rub between his cheeks.

“Just like that,” Bakugou praised, rubbing up and down over the hole. “Let me hear those pretty noises. Open your mouth for me.”

He turned his head to the side, resting his cheek on Bakugou's head, a soft hum of agreement sneaking between his lips, but when the fingers pressed inside of him it quickly turned into a gasp. He sank easily onto the two slick fingers, letting Bakugou take charge of stretching him wider as he instead focussed on grinding his crotch against Bakugou's abs. He knew he was smearing precum on the dark tank top, staining his tight costume, but all he cared about was the hard ridges of muscle he could feel lying underneath.

When Bakugou deemed him stretched wide enough, he shucked his own pants down to his ankles, hitching Todoroki up a little to give them room to come together. He guided the perky ass down onto his cock, savouring the little gasps and whines, his hand sweating up a storm against Todoroki's hip. If he wasn't careful, he'd end up blasting a hole through the fabric for sure.

At least the skin beneath should stay relatively unharmed, he supposed. The perks of his boyfriend's fire quirk.

Todoroki threw his head back against the wall, hands clutching at soft blond locks as Bakugou thrust up into him, strong grip holding him by the hips as he slid up and down the cold tiles. Bakugou's breath hitched, one hand shifting to wrap around Todoroki's shaft, and with a few last strokes, white fluid spilled all over his shirt. He huffed a little, breathless as he made one more frantic thrust with his hips and felt that same sweet release wrack his body.

Limbs trembling, he pulled out as soon as he found the energy, steadying them both with their feet firmly on the ground. For a moment they were silent, other than the heavy pounding of their hearts pressed together and the rough breaths they both gasped.

“Katsuki,” Todoroki said softly, nuzzling once more into the comfort of Bakugou's soft hair. “Feels so good.”

Bakugou wasn't sure why it always made him blush to hear Todoroki say his name, but this was no exception, his cheeks flooding with warmth while Todoroki just smiled knowingly.

“Shouto,” he mumbled, arm snaking around to Todoroki's back. “You ruined my costume.”

“You ruined your costume,” Todoroki argued – even after sex, they could never seem to break that habit. “I'll buy you a new one.”

“I have a spare.”

Eyes meeting for the first time in a long while, Bakugou cracked a little smile, watching a matching one spread across his boyfriend's pretty face.

“I need another shower,” he said fondly. “You wanna join me?”

“More than anything.”
