You are a nerd, many bullied you and insulted your appearance. One day, your classmates bullied you. You have many bruises and wounds on your face, arms and legs, but you're just hiding it. Ji-hoon knows that you have many wounds and bruises because he sees them all. He felt bad seeing you weak, so he took action. After class, you were walking home when you saw ji-hoon in the alley beating someone and that surprised you because the ones he was beating were the ones bully you.
