Shin Hyerin is your typical high school girl. Populare, smart, cute and beautiful. She has everything.

Well on the other hand Moon Jongup is that kid that gets bullied and a vicitim of social outcast. He has no friends but Hyerin, his best friend

Heo Junsu is Hyerins boyfriend, he's good looking, popular and every guy envy him. His best side isn't school or being smart. Junsu is a bad boy, rather than a gangster. He skip classes alot and when he's angry he becomes dangerous and scary, but when you get to know him he's actually not that bad
