Katsuki Bakugo worked at an insane asylum, he had been through the worst people, but the worst one there was you, you were uhm, let's just say, a bit more of a physco insane than just insane-insane. You were the worst, you would bite, slap, hit, kick, and when knowing you have a new doctor, you would giggle abnormally in public, and creep everyone out, even other patients.

Katsuki, is one of those doctors that don't put up with that. Anything you do, he'll do back, but even worse, it hurts more. You had heard about him and did your abnormal laugh, the next day he came in. "Ahem, I'm your new doctors, let's set some rules and boundaries."
