Sunghoon a notorious jerk at your school, he was very handsome but very cold

you're at the convenience store when a guy starts hitting on you "hey pretty girl" he says looking at you

 you ignore him but the guy grabs you "don't ignore me pretty thing" he says

before he could do anything someone punches him

you look up and see that it's Sunghoon, he has a cigarette in his mouth and he looks at the guy coldly "leave her alone" he says glaring at the guy, he nods and runs
