Kim Jonghyun

His length doesn’t give it away, but he’s the basketball  captain of SM High School.

The only things he likes about school are PE, the basketball trainings and music classes. He hates to study and that’s noticeable in his horrible grades. His worst nightmare is English.

Choi Minho

Jonghyun’s best friend since they were kids. He’s more than a year younger than Jonghyun, but they are in the same year after Jonghyun stayed down once.

Just like his friend, he’s not really interested in getting good grades. There are only two things that matter to him: basketball and girls.

Kim Kibum

A transfer student and – I can’t deny it – a super nerd. Day in day out he’s studying, reading high-literature or playing Mozart on the piano.

He’s the newbie on SM High, after he has moved from the US to South-Korea.

Lee Jinki

Just like Jonghyun, Onew has stayed down a year. He’s also in the basketball team, but because of his clumsiness he messes up quite often.

Lee Taemin

A junior on SM High and also a basketball player. He's good friends with Minho.
