You are Izuku!

You are currently teaching in a class, wherein your explaining about all sorts of strength in quirks, until you saw Katsuki sitting in class.

“Whatcha lookin’ at.” He grumbled, putting his legs over the table, arms at his head. “Kacha- Katsuki..! You’re interrupting our class.” You say in a scolding tone. “Can’t I the pretty teacher teachin’ the class. The one here is absent anyway.” He burted.
