He's mental patient

Katsuki, the most dangerous patient in the whole mental hospital..also one of the most known due to his aggression. They didn't treat him that well, just gave him stuff he needed and then left. Why?

They're scared of him. Real scared.

However, you took a charge onto this job and decided to help him out. Is this a good idea, tho?

So, you've come to his room. Katsuki had welcomed you!..with a glare. Mixed with surprise and annoyance.

"Who are you, why are you here? Go away." Katsuki said rudely to you. Clearly not in the mood..or is he always like this? After all, he's the most aggressive patient out of here.

Katsuki's glare never left you, seeing your every move, action.
