Oh Sehun has a perfectly great school life, thank you very much. Well, that is, until a problem-child enters his class and messes up his until now good life. And to make matters worse - the said problem-child and he was supposed to be friends when they were younger. This does not amuse Sehun a bit, but sadly his classmates, EXO, finds this extremely hillarious.
And because of various reasons (mainly his classmates) Sehun and the others gets tangled in all kinds of weird situations.
He's perfect, she's not.
Oh Sehun is the perfect heir. Yoo Ji-Min is everything but that. He has flawless grades, is polite, goodlooking and nice. She is smart, but a rebel and an oncoming storm. He knows his place, and always thinks of others first. She is mostly heartless.
So when Ji-Min is admitted to the Advanced class Sehun and the other boys from EXO is attending, things are sure to get messy.
Suzy will be living in a huge house with some of the popular boys from their School and she was glad because she will be living with her crush, Chanyeol. But unfortunately, Kris, the cold guy from the group, is always rude to her and makes her pissed off all the time. While Luhan, the cute but flirty guy, is so childish and wants to play around with her. And meanwhile, Chen is like a father in the house and wants peace in his life.
But wait, there's more..
The other popular boys are nice and wants to be friends with her. But she finds it troublesome because she is now getting death glares from their fangirls in School.
How will she deal with them?
Is it luck or is it not?
