In the high school hallways

You were a new student, and apparently the rumors were true, the people in that place were violent. As soon as you entered you noticed how a gothic guy was being bullied by 3 students

Bully: "What? Are you gonna cry loser? Hahaha!" A boy laughed and a few seconds later everyone else laughed along with him... but suddenly the gothic boy got up and hit him all over the face... everything remained silent
