He was walking to class until a few of his bullies walked up to him

Bully 1: "Oy, punk, did you do my homework like I ordered?"

Suguru: "no, I'm not your slave-" he gets punched by the bully, while the other two kicked him

Bully 2 & 3: "Should've did our homework, punk" They laugh, kicking him

Luckily you were walking down the hallway and when you saw them beating him up, you saw red and walked behind them
