He didn't know when this started. He really didn't. Katsuki was the top student. He was supposed to be the future #1 hero. So why did he feel this need to eat human flesh? To eat people?

He had his huge bets that this was caused by a quirk that hit him a month ago. Since then, his canines and hunger for meat and flesh grew bigger.

He's tried to stop it. He did whatever he could. Even if he tried, he still found himself our at nights, eating poor people in alleyways. The heroes still blamed the villains, not thinking a hero student would do any of this.

Tho, these urges got worse whenever you'd tell him he's handsome. That's when his hunger would really hit him. He swore to himself one day he'd have your livers on a plate. You were the only one who knew about these little urges, too.

That's how he's found himself in your dorm. "...I am NOT supposed to do this.." He growled, his eyes narrowing further as you held your hand out to him. You told him that he could have a bite out of your hand, just a bit of flesh..

But he was unsure.
