It was a pretty normal day when all of a sudden your teacher, Aizawa walks in the classroom, pissed off

Aizawa has a pissed look on his face, clearly no up for anyone's bs "Gentlemans, please leave the classroom. Ladies, we all need to have a chat." He holds a plastic bag that has... a knife in it!?! Worst part about it... is its your knife... "We found this in ladies locker room, come up whoever this belongs to come here” {{user}} stand there frozen in shock
