Work Text:
Izuku first heard it during lunch.
It was a normal Wednesday, until it wasn’t. Him and the self proclaimed “Deku-squad” were sitting at their usual table, and talking about Present Mic Sensei’s new assignment when Uraraka switched it up.
“Sooooo” she drawled, wiggling her eyebrows, “have you guys heard??”
“Heard what *kero*?” Asui asked.
“We need the details of your topic if we are expected to understand!” Iida chided, which only caused Uraraka to roll her eyes. Todoroki only raised an eyebrow in question.
“I know! That’s why I’m about to tell you!” She proceeded to bring everyone's heads closer and in a whisper said, “apparently, Kirishima and Bakugou are not-so-secretly dating!”
“That isn’t quite surprising *kero*. The two have always been close, and Kirishima has been the only one to get ‘close’ to Bakugou-kun.”
“If they do end up in a relationship, we should fully support them as a class! Though, their personal matters should not be discussed-”
“Don’t be such a party pooper Iida!”
As Iida and Uraraka bickered, Izuku slowly started to pack up his food. There were still around 20 minutes before class, but he had lost his appetite. None of his friends noticed as he got up and walked to the dorms.
When he got back into his room, he let his tears fall.
Of course Kacchan would like someone like Kirishima. He was strong, persistent, and anything that Izuku wasn’t. Izuku sat at his desk with his head buried in his arms to muffle the noises of his sobbing.
He had always known Kacchan would be too far for his reach. Even then, Izuku hoped that Katsuki wouldn’t notice anybody else, not until Izuku proved his worth.
He didn’t know how long it had been since he started crying, but soon a series of knocks banged on his door.
“Deku-kun! Class is almost starting!” He could hear Uraraka’s call.
“Midoriya-kun! If you are not feeling well, as the president, I will inform Aizawa-sensei if it is needed! WIll you be alright to come to class?” Iida’s booming voice was also heard.
Izuku quickly wiped his face with his uniform sleeves and gave his eyes a quick rub, hoping it wasn’t noticeable that he had been crying before opening the door with a fake smile.
“I’m okay! I just forgot a notebook and came to get it! I guess I lost track of time!” He laughed it off.
“You should always keep all materials with you at any time! There are many situations where…” As Iida babbled on about the different scenes, the trio made their way to class.
Much to Izuku’s dismay, Katsuki and Sero were both at the door and turned their way as they walked in. Izuku tried to put on his best smile, but failed.
“Oi nerd! What’s with you? The hell you’ve been crying for ah?!” Bakugou yelled.
“Oh-um!” Izuku didn’t know what to say. Thankfully though, he saw Todoroki wave the trio over to him and Asui. “Nothing! Bye! Gotta - um - Todoroki-kun! See ya Kacchan!” He sped away quickly.
“OI-” Katsuki tried to grab him as he walked by but the shitty nerd dove to the side too quickly.
Unfortunately, Katsuki wasn’t able to chide the nerd for his actions, since Aizawa decided that now was the perfect time to join the class.
Doesn’t mean that the thought wasn’t lingering in Katsuki’s mind for the rest of the day.
◑ ━━━━━━━━━━━━━ ▣ ━━━━━━━━━━━━━━ ◐
Katsuki’s second attempt to approach Izuku was on the way to the dorms after class.
He had been ignoring his friends (he’ll be caught dead calling them that) before noticing that the nerd-squad was right in front of them. He also could notice the limp in Deku’s step (which only he ever noticed) that only occurred when he was sad.
“Hey nerd!” He bellowed, speeding up. He could hear Kaminari’s complaints about not letting him finish the story, but there was no point since his relationship would flop in two days.
“U-uhm Kacchan! W-what do you need?” Deku turned around and Katsuki could see nervousness in his eyes. And something else. Pain?
“The hell’s with you? You ignored me in class today and have been acting weird! You think you’re better than me or something? HAH?!”
“N-no Kacchan! Nothing like that!” Izuku assured him, “I-I’m just tired, so I'm gonna go lay down. Um- bye! Also, I won’t train with you today! Bye!”
“HEY WAI-” before Katsuki could finish ranting about Deku’s lack of attention, the latter sped off towards the dorms, leaving Bakugou behind.
Bakugou clenched his fists and stormed off to his room. Where he knew Kirishima would be waiting.
◑ ━━━━━━━━━━━━━ ▣ ━━━━━━━━━━━━━━ ◐
As Izuku entered his room, he saw Kirishima entering Bakugou’s dorm as well. Kirishima gave a small wave, but he was only able to give a sad smile before rushing into his room.
As soon as he made it in, he jumped on his bed and cried into his pillows.
◑ ━━━━━━━━━━━━━ ▣ ━━━━━━━━━━━━━━ ◐
“Dude you gotta communicate more! Get to know him better than anyone else” Kirishima said.
The two bros were currently in Bakugou’s room, with Bakugou at his desk while Kirishima sat criss-crossed on the bed. Katsuki had told Eijirou everything and neither one knew the reason for Midoriya’s behavior.
“I do know him better than anyone else!” Bakugou replied, turning in his chair. “I know more shit about the nerd than his mom probably does!”
“Try talking to him, Kats.”
“Oh yeah, cause that worked out earlier didn’t it? He definitely didn't just ignore me!” Katsuki sarcastically said back.
Kirishima only rolled his eyes and sighed. Katsuki had given him the permission to use his first name the same day that he had asked for help. Kirishima was more than happy to help, but he had not expected the help to be about Midoriya. Or the fact that Bakugou had a crush on Midoriya, and could never communicate well enough to be nice.
“Just….act normal for a while. Do your regular outburst and comments, but slip in a compliment here and there. You also mentioned he likes having his hair ruffled. Do that a couple of times!” Kirishima advised.
Katsuki sighed. “Yeah, okay.”
◑ ━━━━━━━━━━━━━ ▣ ━━━━━━━━━━━━━━ ◐
The next few weeks were hard on both teens.
Izuku was avoiding Katsuki as much as he could, and it became painfully obvious. A couple of times, some other classmates had asked if they had some sort of horrible argument. Katsuki always just yelled at them to mind their damn business while Izuku kindly denied everything.
Anytime Katsuki tried to talk to Deku, he would come up with some excuse.
“Sorry Kacchan! I’m really tired!
“Sorry Kacchan, I have to go study!”
“Sorry Kacchan, Todoroki-kun is calling me!”
------
After about 2 weeks of non stop excuses, Katsuki had enough. His anger levels were high. What had he done? He had even asked All Might for fucks sake! Not even their mentor had any idea!
So, today, instead of running to Deku in class, Katsuki ignored him the entire day. His plan would wait until after school.
Around 2 hours after school had let out, Bakugou emerged from his room with Kirishima. Eijirou wished him luck and went to go find his girlfriend.
Katsuki walked over to Izuku’s room, and instead of knocking, barged right in - of course, the nerd never locked his door.
“Wha- KACCHAN?! THAT'S INVADING MY PRIVACY!” Izuku jumped up. He had been working on some english homework before being rudely interrupted.
“Shut up!” Katsuki yelled. He turned and locked the door before walking over, grabbing Izuku by the collar, and throwing him onto the bed.
“He-OOF!” Deku jumped twice on the bed before flattering out.
“Kacchan! What are you doing here?!” Izuku exclaimed, sitting up. Katsuki could already see tears starting in his eyes. What did he do that was so bad that caused the nerd to cry at the sight of him?
“Alright what did I do?” He asked.
“H-huh?”
“Don’t play dumb IZUKU!” Izuku’s eyes went wide at the use of his given name. “You’ve been ignoring me for weeks! What did I do? Not train with you?!”
“Wha-Kacchan I haven’t been ignoring you!” Izuku lied. But he could tell Katsuki didn’t fall for it. He only looked away in shame. Never in any of their lives, even when things were rough, was lying allowed.
Bakugou sighed and got on his knees on the floor in front of Deku, placing both hands on his knees.
“Deku. What did I do?” He asked as calmly as he could.
“Ne?! K-Kachhan, I promise, you didn’t do anything! Not intentionally at least…” Izuku mumbled the last part.
“What? What did I do unintentionally?!” Bakugou said, surprised. So he did do something?! He tried replaying everything that involved Deku in any way that occurred before this mishap.
“Just- why are you even here Kacchan?” Izuku sighed. “Y-you should go to Kirishima-kun. I bet he likes you back…” one by one, tears started to fall.
Katsuki blinked slowly, comprehending what Izuku just said.
“Wh-wh-...HAH?! LIKES ME BACK?!” He yelled, getting up and stepping away. “THE FXCK ARE YOU ON ABOUT HAH?! I DON’T LIKE SHITTY HAIR!”
“You don’t need to deny it Kacchan! It would've been him rather than anyone else!” Izuku yelled back, standing up, secretly thanking the dorms for being soundproof, because nobody needed to know about his unrequited love. “You’ve only let him get close! He’s always been by your side! He’s amazing, smart, good-looking, happy, and- and....and everything I’m not.”
Bakugou stared and blush spread all across his face, along with the look of realization. Suddenly, he burst out laughing.
Izuku took his laughter as something else and the tears turned into waterworks. He went back onto his bed and sat down.
Katsuki then noticed Izuku’s mood and stopped before walking over to Izuku. He sat on the bed and pulled Izuku into his lap, head tucked under his chin.
“Y-you fking idiot. Is this what this is about? You were jealous, because you thought I liked hair for brains? That idiot is secretly dating Pinky. He may look like a gay mess, but he’s really just a bisexual bastard.”
Izuku couldn’t help the relief that washed over him. That is, until he noticed the position they were in. He squirmed and scrambled to get out of Katsuki’s hold, but when not using quirks, Kacchan was at least 5x stronger.
“So...why were you jealous, hmm?” Bakugou teased. Izuku felt his face flush and was thankful Bakugou couldn’t see it. But it didn’t last long since Izuku was turned so one leg was on either side of Katsuki’s and his chin was lifted up to see Katsuki’s (sexy) smirk.
Izuku’s face flushed and he looked to the side. Bakugou gave a small chuckle before leaning down and connecting their lips.
Izuku happily granted him access when he felt Bakugou asking permission to enter his mouth. He wrapped his arms around Katsuki's neck as heir tongues swirled together. Izuku moaned into the kiss, before pulling away out of embarrassment.
Bakugou laughed and pulled Izuku to his chest and laid them both down. Izuku happily snuggled into his chest, but one question lingered in his mind.
“K-Kacchan?” He mumbled.
“Hm?” Bakugou hummed, threading his fingers through the smaller male’s curls.
“Are-c-can we start dating?” Izuku shyly asked. He had always wanted to date Kacchan.
“Hmmmm...no.” Bakugou joked. But Izuku took it seriously and stiffened until Bakugou continued. “Why date? Let's skip straight to the marriage cause I ain’t leaving you.”
Izuku lifted his head quickly and stared at the male below him, who was smirking handsomely.
“E-EH?! MARRIAGE?! ME?! NOW?!” He started mumbling under his breath and Bakugou laughed before pulling the other down for another quick peck on the lips.
“Don’t worry, I’m kidding. About the now thing. That’s no doubt happening later, but for now I’m fine with where we are.” He said.
Izuku smiled and gave a quick kiss on the cheek before hiding his red face in the crook of his Kacchan's neck.
