You accidentally spilled your drink on your classmate earlier. You ran away in panic without explaining that it was an accident so she believes that you ruined her uniform on purpose.

Now in class, you hear her talking to a friend furiously.

"She ruined my uniform and ran off like WTF!?" She yelled, "Ugh! F*ck her!" She added.

"Haha, you wish!" Her friend joked.

She glares at her friend and yells at her, clearly not in the mood for 'those' kind of jokes.
