Midoriya was a cinnamon roll. That was the politically correct term for his personality. If talked to anyone on campus they would describe him as a happy, bubbly, kind hearted loyal friend. And on all counts that was true. On a university survey, he was even rated #1 most likely to open a shelter.
So everyone remembers the incident with astounding clarity.
“Kacchan, what’s that?” Midoriya asked. Katsuki paused in pulling his books out of his bag and looked towards his boyfriend.
“What’s what?”
“That.” he said, rising from his bed where all his study material was laid out and reaching into Katsuki’s back pack to pull out an envelope.
“The hell?” Katsuki mumbled and reached for it. He ripped it open after checking the outside, blank, and opened up the one folded sheet of paper. Midoriya looked at it over his shoulder and his rage boiled inside him.
“ Dear Katsuki- senpai,
I really like you. You are super amazing and smart! You were really kind to me when I first joined the club and it left a big impact!
I love how much you care about the team and how hard you work. I really admire you!
Please be my boyfriend.
Yours,
Kirishima Eijirou.”
“What the fuck!” Katsuki snapped and before he could do anything Midoriya ripped the letter out of his hands. “What the hell, nerd!”
“Let me handle this, Kacchan.” he smiled, folding it up and putting it in his back pocket. He grabbed Katsuki's face and pressed a hard kiss to his lips. “Now, do you have any interest in Kirishima?”
“Of course not!” he scoffed and Midoriya smiled.
“Then let me handle this.” The blonde frowned for a second before relenting and pulling him in for a longer deep kiss that quickly escalated, resulting in all his papers being shoved to the floor and his neighbors losing sleep that night.

“Hi!” the door squeaked open to reveal a curly haired Midoriya. It was a sophomore club room that he would normally have nothing to do with and no reason as to why he would be there. Except for one personal reason.
He ignored the student standing at the front and plopped down next to his target.
“Don't mind me, please continue.” he grinned and most of the kids knew of him so the pause in conversation didn't last long. Of course most students knew who he was. He got around, and not even in a slutty way. He was in a lot of social circles, he enjoyed parties and he was super easy to talk to.
The club continued on with Midoriya seemingly paying attention, even adding little notes here and there because it was on astronomy and that was one of Katsuki’s favorite topics.
After the club ended some of the students asked him questions he had no trouble answering and kept an eye on the red head packing up out of the corner of his eye. Once he left he jumped up.
“Sorry, Sasha, I'll fill you in later.” he waved with an easy smile and she waved back in confusion but he was gone.
“Hey, Kirishima.” he called loudly, in a hallway with a tall ceiling it echoed and said redhead froze.
“Uh, yeah?” he asked, turning to face him.
“I wanted to talk to you.” he gave him a disarming smile that the sophomore returned.
“Sure, I'm a little surprised because you're a senior. Isn't there a senior astronomy club?”
“There is indeed.” he put a hand on his shoulder and casually started moving towards the middle of campus. He continued to chat with him to keep him occupied and before long they were in the middle of a busy quad.
“By the way!” he said and pulled the unassuming paper from his pocket. “I heard you have a crush.” he said and watched the blush spread over his face.
“I umm. I didn't know it was well known..” he muttered but he could hear it just fine.
“Oh it's not!” he giggled and pulled out his phone. Kirishima watched him curiously before Midoriya turned his phone up and put it on speaker phone. Kirishima gave him a funny look and Midoriya just giggled putting a finger to his lips.
“ Hello ?”
Kirishima’s face grew even more confused.
“Hi babe!” he chirped and watched his face fall.
“Deku? What’s up?”
“Not much, I just wanted to call to say I love you.”
“I love you too, bunny.” he could admit that it gave him sick satisfaction to see the tears building but he wasn't done yet.
“That reminds me.. You know we both don’t have morning classes tomorrow.” he trailed off and you could hear shifting over the phone.
“We don’t do we.” he hummed and Midoriya shifted slightly, his face twisting with glee.
“So what do you say about me riding you till I break tonight?” He watched a tear fall.
“You can ride me the first round but I get control the second time. I’ll make you cum so hard you’ll see stars, baby.”
“Already planning for round two?”
“Deku, you know we can't stop at one. We have never managed to not go again.”
“That’s just because Kacchan’s cock feels so good~” he hummed in delight and he heard Katsuki’s throaty chuckle.
“You bet your tight ass it does.”
“Sounds fantastic, babe. I’ll see you soon.”
“Come over now, sweetheart.” he commanded and Midoriya giggled.
“Yes, daddy.” he quickly hung up and unfolded the paper in front of a sniffling Kirishima on the verge of sobbing. It was the love letter with big red sharpie written over the top.
KATSUKI IS MINE
Kirishima immediately started sobbing and ran away. Catching the attention of the rest of the quad who wasn't in earshot of the conversation. Midoriya giggles morphed into sadistic laughter before he started for his boyfriend’s dorm, more than ready to have his brains fucked out of him.
The surrounding students watched the chaos unfold and the story of what happened morphed and shifted like all rumors. but one thing stayed the same.
“Stay away from Midoriya’s boyfriend”
