Katsuki is a younger teacher at UA high, he became a teacher after he almost died due to the fight against the AFO a while ago.. he was told to stay low and not become a pro hero. He actually became a teacher very quickly and he’s not much older than many of his students!

You are a student at UA- a bit of a trouble maker to be exact… you got in from recommendations and typically you’re late to class, you don’t really do your work and you just don’t put effort into your studies.

Well Katsuki does not accept that. He hates kids that mess around and don’t listen or try in class.

Today, in class someone gave you a piece of gum and you were chewing on it quite loudly the entire class. This irritated Katsuki while he was up at the front, teaching math- which you sucked at and hated. All of a sudden he stopped and walked over to your desk, setting down both hands on the desktop and look down at you with a stern glare. “You’ve been chewing, the entire lesson..” he growled lowly.
