Yongguk, Himchan, Daehyun, and Yougjae are a part of the popular crowd at school, with their good looks and status they were always being followed and having kids wanting to be friends with them. They were also trainees and were hoping to debut together in a new idol group, not many kids new that Yongguk was an underground rapper which was fine with him because he needed to stay out of trouble if he wanted to debut. Fans of underground rappers could get a little aggressive towards each other, and he had promised his CEO not to get into anymore trouble. Jongup was the newest trainee at their company and they had taken him under their wing at the company and at school. Jongup preferred to not hang around them at school though because he didn't like all the attention, he was quiet and a really good kid and the older boys doted on him. Zelo was a new kid at school who stayed to himself and didn't talk to anyone, the others had seen him and stayed away because he was getting bullied and they didn't want to get involved. Zelo had seen the group of older boys and how close they were and wished to have something like that for himself but it wasn’t meant to be. 

Yongguk: 19, last year of highschool he's making up a year due to some poor choices and getting in trouble. Trying to keep his identity a secret from everyone at school until after he graduates and is able to debut in an idol group. May seem mean but is very lovable to those that he's close to.

Himchan: 19, many are surprised that he and Yongguk are friends but they have been friends since they were little. Ending up having to repeat a year like Yongguk but for different reasons, is the mother of the group loves to take care of his friends even if he seems stern.

Daehyun and Youngjae: 17 years old, joined the agency together, have beenf riends since they were toddlers have started to explore their relationship when they realized that they liked each other more than just friends. Their hyungs and company support them and they couldnt be happier.

Jongup: 16, shy an amazing dancer and signed up with TS entertainment a few months after the others had so he was the youngest. Jongup doesn't talk to much but has a big heart and wants to make the older boys proud of him. 

Zelo: 15, shy and doesn't talk ever..gets made fun of and bullied all the time. Just moved to the school where he sees a group of boys who look like they genuenely care about each other and wishes he was with them but knows he'll never be good enough, tries to stay in the shadows until something brings him closer to them.
