My name is Yoo Youngjae I'm 19 years old I'm an only child and I have 3 friends Junghong,Jongup and Yongguk they have been my friends since as long as I can remember we do everything.But don't be surprised I'm still very shy and antisocial when it comes to people.Until I met him...

I'm Junghong mostly liked being called "Zelo" I'm 18 years old youngest out of all my friends and I might have a little crush on Jongup. 

I'm Jongup I'm 19 out of all my friends I'm  closest to Yongguk. I'm best friends with Yongguk, Zelo and  Youngjae since we started high school.

I'm Yongguk I have known Youngjae the longest he has always been isolated from people since his mom died and he was left with his abusive dad which he doesn't like talking about and I'm the only one who knows about it.
