Kai has always been and still is one of the most handsome men in school. The lead of the basketball team, rich, popular, and good looking. It's obvious that he's got it all.

Oh Sehun has always been Eunmi's nightmare ever since she defied him.

He never meant it. The guilt turns his life into miserable. "I'm sorry..."

     Song Chae-Yeong, that's my name. The high school I go to, Prím Ellite High School. Life was perfect, it was perfect. I met a boy, his name is Oh Sehun, sometimes I call him the devil too. He likes to darken my days, to mess with me. For the past two and a half a year he's been bullying me. What can I do to stop him? Nothing, because he'll only get worst. 

Irene and her clique consisting of Yeri, Kai, Chanyeol and Suho are the infamous bullies in school. They pick on almost everyone who cross them or seem weak but out of all the victims, Irene's favorite was the nerdy Kang Seulgi.

The right one will love you for what's inside.
