The one thing most of the class does not know about Katsuki and Izuku is their relationship.
The two have been dating since the summer before their first year at UA. They told their family but decided not to tell anyone else. Knowing that becoming hero’s meant having less privacy the two boys wanted something as personal and intimate as their relationship to stay a secret.
Their relationship started off pretty rocky. They weren’t surprise none of their classmates had figured them out during the first two years at UA.
Katsuki had always thought it’d be Izuku who would be the one to give them away. However, what he didn’t expect was that it’d be him giving them away during the first few weeks of their third year. He especially hadn’t expected it to be something as little as a simple pet name.

Most of the class, with the exception of a few classmates who had gone home for the weekend and a very reluctant blonde, was downstairs in the common area for a movie night.
Izuku had his place on the couch waiting patiently as a few others picked the movie. After a couple minutes he heard a familiar voice yell in the hallway. “Do you want me to blow your ass up!” As he looked over he saw Katsuki with his hands up and pointed at Mina.
“Come on Bakubabe it’ll be fun” Mina whined while trying to get closer without getting touched by the sparks popping from the blonds hands. “Bullshit, i’m not sitting with you extras for two hours just for some lame ass movie” He grunted before grabbing a cup of water and heading back to his dorm.
Seeing this Izuku was a little sad he wouldn’t get to sit with his boyfriend but he didn’t dwell on it too long as he knew he’d be seeing the other in a couple hours. After the war, Izuku had been getting nightmares of Katsuki during the war. He’d tried a couple different things before finally getting sick of waking up every night for a couple weeks and decided to talk about it with his boyfriend. After a couple nights they’d discovered sleeping in the same bed helped.
Eventually everyone in the commons agreed on a movie and turned out the lights before starting it. Izuku shot a quick text to let Katsuki know when he’d be in his room before setting down his phone and watching the movie.

Once the movie had ended Izuku had begun to get up to head to bed before he was quickly stopped and been roped into talking about the movie. He had expected to only been down there for about a half an hour or less.
Though that didn’t quite happen as it had been a little over an hour and everyone was still talking. Looking at his phone he saw it was already almost 11pm and had planned to fake being tired to try and sneak away. Just as he was about to start speaking his phone starting to ring causing everyone to turn and look at him.
A couple classmates make quick comments of asking who it was before he looked at his phone. “It’s just Kacchan” Most of their faces morphed from one of curiosity to one of confusion. “Answer it! I wanna say hi!” Kaminari yelled as he jumped from couch to couch before grabbing Izuku’s phone and answering the call himself to put it on speaker.
Just as Kaminari opened his mouth to say something he was interrupted by the boy on the other side of the phone, “Where are you, baby?” Gasps were heard and the green haired boy let out a loud shriek before grabbing his phone and sprinting up stairs.
He could hear majority of his classmates following after him as he ran. Using one for all he managed to beat everyone to Katsuki’s room and quickly slammed the door shut before running over and jumping onto the bed. Throwing the blanket over himself and hiding behind Katsuki while quietly whispering. “The class heard you, Kacchan”
Less than a couple seconds later he heard the door swing open. Hiding himself the best he could under the blanket and hoping nobody could see him in the dark room.
“Bakubro where’d Midobro go” Izuku heard Kirishima say along with a lot of foot steps all huddling around the door. “Like I know where the shitty nerd went” Katsuki grumbled out in response.
Kaminari giggled before replying, “Aw why the switch in names?” Katsuki growled without saying anything back.
Just as Izuku thought they’d be in the clear until morning his luck had ran out as he let out a sneeze from underneath the blanket. “Shit” Katsuki quietly cursed right as someone in the doorway flicked the light on in the room. “Wait a second…” Ochako made her way over to the bed and pulled the blanket.
“I knew it!” gasps could be heard as Izuku was revealed from under the blanket with his face hidden in Katsuki’s back and grabbing onto his arms shielding himself.
Izuku slowly sat up from his spot without looking at his classmates. After a few seconds all that could be heard in the room was 50 different questions all being yelled at once.
“Shut the hell up!” Katsuki yelled and in an instant the room was quiet. “Are you two dating?” Momo said being the first to speak. “Fucking obviously” Katsuki said as he rolled his eyes. A couple others asked their share of questions like, “How long?” “Why’d you guys keep it a secret”
The couple calmly answered the questions until one particular one came from a rather excited Kaminari.
“Have you guys fuck-” the question was quickly shut down by Katsuki. “All of you get the fuck out of my room” they all pouted slightly before making their way out. Leaving just one person left standing in the doorway. “I’m taking that as a yes by the way” Kaminari smirked “Get out!” Katsuki said with a pop coming from his hand.
The door was quickly slammed shut leaving the couple to themselves.
“I’m sorry he just took my phone an-” his apology was put to an end as he felt soft lips pressing against his own. “It’s okay. They were bound to find out sooner or later anyways”
The blond got off the bed and turned off the big light leaving just his lamp desk to light up the room. Making his way back over to the bed and crawling over to be hovering right above the blushing green haired boy.
“At least we don’t have to hide anymore” He said with a smirk before leaning down to once again connect their lips.
