Xiumin- 18 years old. Eldest and toughest.

Luhan- 18 years old. Cheerful but Manly, well atleast that's what he thinks.

Baekhyun- 17 years old. Sassy.

Chanyeol- 17 years old. Loving and caring.

Tao- 16 years old. Full of aeygo but he's tough.

Kai- 16 years old. Joker but sometimes, he can be a little irritating.

Sehun- 16 years old. He just turned 16 and he's the maknae. He's face is usually expressionless. But he has this side that only his brothers can see.

Side characters:

Lay- Kai's dance partner. 17 years old. He also develops a liking for sehun because he can't resist the charm of the said boy.

Suho- 18 years old. A straight A student. Xiumin's bestfriend. He dislikes sehun but he doesn't tell Xiumin. Sehun will make him like him though.

Kris- 18 years old. The council president. He hates everybody. He hangouts with them though.

Kyungsoo- 17 years old. Baekhyun's friend in vocal class. Hangouts with them.

Chen- 17 years old. A troll. He likes Xiumin. He is good friends with Sehun. He's not his best friend because Sehun is uninterested with everyone. 

These 12 boys all hangout together. They are called Exo by the students. They are all handsome but Sehun stands out the most. Everyone thinks he's cool because he doesn't show interest in anyone or in anything. He is a brat which everybody likes. (Except Suho and Kris)

What will happen to their life? Would they deny their feelings towards their brother? Or would they just go with the flow and claim Sehun as their own?
