A/N Disclaimer: this chapter talks a little about their backstories, but I haven't read much of the manga, so it probably isn't accurate. When I do eventually get around to reading it I might update it, but for now...I guess just deal with it XD Otherwise thanks for reading and enjoy!

Kirishima knocked on the door cautiously.

"Yeah, what is it?" an annoyed voice called from inside.

"It's me Bakugou," he answered. "I was wondering if you could maybe help me with my homework?"

The door flew open to reveal Bakugou glaring at him from under his scruffy ash-blond hair. He sighed, "Wasn't everything due in class today?"

Kirishima laughed nervously, grabbing the back of his neck and avoiding eye contact as he responded, "Most of the teachers said they would let me turn it in on Monday. I'll just lose a few points for it being late."

"So, they haven't realized how pointless it is to give you a second chance...even though you had a week to get it done."

Bakugou seemed angry as he said it, but he left the door open and retreated into his room again. Kirishima knew him well enough to consider this his version of an invitation. It meant that he wasn't necessarily unhappy to see him, anyway.

"Well it isn't that pointless," Kirishima protested as he followed him inside. "I mean I'm here trying to get it done now, aren't I?"

Bakugou just rolled his eyes at him as he sat on the edge of his bed. Kirishima joined him after looking around the room for a moment. It wasn't his first time seeing the other boy's room—they were best friends after all and he had asked for help on his homework before—but it still amazed him. Bakugou was surprisingly tidy, keeping only a few necessary pieces of furniture and keeping the room clean and relatively plain. Kirishima's was just the opposite: his room was cramped, messy, and crowded, making the space seem much smaller than it actually was. In Bakugou's room he felt he could breathe, and it was one of the major reasons he loved studying in his room.

The other reason, of course, was just spending time with him. Spending his Friday night studying and doing homework wasn't exactly his ideal hangout but spending that time with his best friend made it worthwhile. Not to mention Bakugou was such a loner he could make it difficult to hangout and have fun, so Kirishima got used to finding new ways to spend time with him however possible. And obviously Bakugou seemed to value their time together somewhat; he wasn't constantly threatening to kill Kirishima anyway. Just most of the time.

Then again, sometimes Kirishima wondered if he maybe could have liked Bakugou as more than a friend. He had never had much interest in girls anyway. But he had never really had a crush on anyone that he knew of, so he wouldn't really know if he found guys or girls particularly more attractive. But over time he watched Bakugou lower his defenses when they were alone, and Kirishima felt something. He certainly admired and looked up to him as the manliest man in their class, but he didn't think that would really count as a crush. But, he supposed, he had certainly noticed some of his physical features, such as his explosive but soft hair, his sharp jaw, his lean but surprisingly muscular body, the fiery passion in his eyes with everything he ever did.

Here Katsuki Bakugou was, giving up his Friday night for some stupid kid he still seemed to forget the name of occasionally. But he seemed almost...content. Not happy necessarily, but he wasn't acting like the usual King Explosion Murder either. Kirishima decided he wanted to test himself to see if it could possibly be something more than friendship he was feeling, praying he wouldn't be noticed.

During the course of their study session he found excuses to get closer to Bakugou and make light physical contact wherever possible, just things like brushing his hand as he reached for a pencil or bumping their legs together when he adjusted his position. It never seemed like Bakugou noticed. Kirishima was relieved, but something in him was a little disappointed at the same time. After a while he gave up in his testing; he had collected all the information he needed from that little experiment. He turned his eyes back to the papers as he struggled to comprehend what Bakugou was saying. But he did learn one very important thing from their study session.

He undoubtedly had a crush on Bakugou.

The thought made a little blush creep up on his cheeks, but he hid it well as he continued trying to grasp the concepts from their lessons. But it was far too late now. He was already right up next to Bakugou, shoulders brushing the slightest bit whenever they moved. He could hear the other boy's breath, feel the heat radiating off of him, see his red eyes without their usual anger tucked away under the ashen strands of his hair.

"That it?"

"Huh?" Kirishima asked as he was forced suddenly into reality.

"Did you have any other homework you needed to do before Monday?" Bakugou clarified with mild annoyance lacing the tone of his voice.

Kirishima shook his head mostly to clear it as he said, "No, this is it. Thanks man."

"Well you could stay for a bit anyway if you wanted. I don't have anything, better to do," Bakugou suggested, much to his surprise.

Kirishima laughed. "Yeah, me neither really." He set his homework aside and leaned back on his hands as he looked over Bakugou, wondering what he had in mind.

The other boy leaned back as well, looking back at him apathetically. Casually he said, "I don't know much about you when you were a kid. I bet you had a lot of friends back in middle school."

"Well sorta..." Kirishima paused as he tried to think about it more. "I used to hang out with this one group but we weren't really good friends, ya know? Mina was pretty nice though, I like her. I'm happy to call her a friend."

"That's the pink one?" Bakugou seemed to smirk at that. Was he making a joke?

Kirishima laughed, "Yeah she is. But what about you? Did you at least have a friend group?"

Katsuki shrugged. "I had a gang of sorts I guess. Just people that thought I was cool and always wanted my attention. I always had to prove I was the best—that I could do anything I put my mind to. But there was Deku. Every. Fucking. Time. He said he was going to go to UA one day, even though he didn't have a quirk. But I had one. A powerful one. But there he always was, in my face, insisting he was going to be great just like me. Now all of a sudden he has a quirk, and a powerful one at that, out of absolutely nowhere. I don't know how, but now he's an actual threat to me becoming the number one hero."

He stopped suddenly when he realized he had started ranting, then quickly wrapped up what he was saying, "So no, I didn't really have good friends I don't think, besides some other idiots who always looked up to me. But at least they knew they could never compete with me. I didn't really care for friends. Not that no one tried."

"Well now you're stuck with me," Kirishima teased, punching him in the shoulder lightly.

Bakugou just huffed in response and they lapsed into a comfortable silence as they thought about what the other had said. Though, truthfully, it pained Kirishima to hear Bakugou talk about his past like that. The words sounded indifferent, but the fact that he was in quiet contemplation suggested he was more troubled about it than he was letting on.

So Kirishima decided to mischievously lighten the mood. "Did you ever have any girlfriends? Or kiss anyone?"

The questions caught Bakugou off guard and he raised an eyebrow skeptically. "No. I guess there were a few girls that showed interest but I didn't really care." Almost as a side note he added, "Cause I didn't want to get into any trouble or anything, and ruin my chances of getting into UA."

Kirishima was curious now, and intent on getting answers while Bakugou was in such a sharing mood. "Have you ever wanted to kiss someone?"

"I guess."

"Who was it?" He asked, curiosity piqued.

"Why do you care so damn much, spikey hair!?" Bakugou countered angrily. After a moment he calmed down a bit and growled back, "What about you? You ever kiss anybody?"

Kirishima shrugged and answered as nonchalantly as he could, "I never have but I want to."

"Want to, not wanted to?" Bakugou grumbled confusedly. "What, like someone from class?"

Kirishima's eyes widened, and he felt a blush creep up on his cheeks. That's when he panicked and completely lost the filter that regulated what his stupid brain wanted him to say, "Well yeah I guess so but not that I really-" He was interrupted by Bakugou mumbling something. "What was that?"

"I said IF YOU TELL ANYONE YOU'RE DEAD!"

Before he knew it Bakugou was kissing him. It was a light kiss, nothing more than their lips briefly touching for a moment, but it sent Kirishima into shock and he froze. Bakugou must have sensed this, because he withdrew a second later with a cold scowl on his face.

"I mean it crimson idiot. If you tell anyone about this you're DEAD," Bakugou glowered. Kirishima winced slightly; he must have taken his reaction as a negative thing.

"You're the idiot this time," Kirishima scoffed.

Before Bakugou could react, he grabbed him by the collar of his shirt and pulled him closer for another kiss. This one was different, somehow. It was the same kiss really but this time they were both at least somewhat prepared for it. Bakugou froze for a second as well, but then his whole body relaxed as he accepted the fact that Kirishima was kissing him back. Neither of them could believe this was really happening.

Then Kirishima felt the other boy's teeth on his lips and instinctively parted them. Bakugou pushed his tongue inside, deepening the kiss. It was gross, sloppy, and clumsy, but it was everything. Eijirou felt hands in his hair, on his chest, moving along his legs—he couldn't keep track of them as his mind turned to mush. Eventually the hands settled on his shoulders and gently pushed them apart, leaving Kirishima's head reeling as he struggled to regain his senses.

When they finally pulled apart they were both breathless, and Kirishima saw an entirely new look in Bakugou's eyes. The red irises were alight in his fiery gaze, but not in his usual murderous sense. They held a similar passion and intensity that Kirishima had grown rather fond of and admired in Bakugou, but this look was something entirely new—and intoxicating. Whatever the look was, Kirishima felt that his own eyes were probably matching it. He was upset that their kiss had to end, but in that moment he realized it was probably for the best.

Kirishima was still breathless as he said with wonder, "That was..."

"Something we should be careful about," Bakugou said with a humorless laugh as the fire slowly died in his eyes. "We should maybe practice more caution when someone could walk in at any moment."

"Right," Eijirou answered, nodding his head as he vaguely comprehended what he was saying. "Won't...won't happen again?"

"I hope it does," Bakugou answered swiftly with a little smirk, regaining some of his confidence. "I just...never expected this to happen tonight."

Kirishima's mind cleared up a bit and he gave him a smirk of his own as he teased, "But you were expecting this to happen at some point?"

"Shut up," Bakugou said a bit sheepishly.

Admittedly, Kirishima thought it looked rather cute to see him act a little shy. He awkwardly turned away and gathered all his homework together, mostly to hide the blush that was slowly intensifying on his cheeks and got up to leave. At the last second he whipped around to kiss Bakugou one last time before sheepishly turning away again and heading for the door.

"See you at breakfast?" he called back hopefully as he opened the door.

"Yeah, whatever," Bakugou answered, returning to his usual demeanor. But Kirishima knew it was an act this time. A little softer but begrudgingly he added, "Night, Kirishima."

"Night, Katsuki," Kirishima answered as he swiftly left and shut the door.

Bakugou called him by his name! And Kirishima had called him back by his first name! It made him feel all warm and fuzzy inside as he made his way to his own dorm right next door. He tossed his homework aside in a random pile in his room and collapsed on his bed, staring at the ceiling as he replayed the memory over and over in his mind. He could still feel his warm hands, his soft lips, his heavy breath. He could see the look in his eyes: the manly determination and raw power burning within him. And his tough guy façade, which crumbled whenever Kirishima was alone with him. There was no doubt about it. He was undeniably, hopelessly in love with Bakugou.

***

Bakugou laid his head back against his pillow and let out a small moan when he felt teeth lightly graze his neck. A firm hand ran slowly down from his shoulder, lightly tracing his nipple on its way down before gliding over his abs reverently. His breath hitched as the hand found the edge of his boxers and started playing loosely with the elastic. Kirishima sat up a bit to adjust his position, letting Bakugou see the smirk on his face and the light in his eyes. He leaned down again to kiss Bakugou on the lips, kissing him deeply and possessively. Katsuki's breathing got heavier as Kirishima's hand ventured lower, until—

He woke with a start, bolting upright in bed and panting heavily. He could feel heat rise in his cheeks when he realized what he had just been dreaming about, and a layer of sweat coated his entire body. He was shaking for a minute as he tried to bring himself back to reality and settle the storm raging in his mind.

Seemed to him that it was going to be a long, awkward day after that experience.
