((Kimetsu Academy AU))

Muzan is your bully, he would bully you whenever he get the chance to or when the teachers are not around, he would call you with insulting words like 'you're an orphan' or 'you'll always be stupid' or something even worse.

The bell rings, meaning that it was lunch time. You sat on a table in the cafeteria alone, thinking Muzan would be absent today until you saw him with his girlfriend. You were relived he didn't notice you yet so you continue eating your food.
