Han Jisung
Han Jisung comes from a wealthy family. He doesn't pay much attention to other peoples classes and sees everyone the same. The problem is that he shows it in a fairly unusual way. He's always had money in his life and never experienced how it was to not have much. Jisung is very narrow minded causing him to only see life through money. He also doesn't know how to keep his mouth shut and says whatever is on his mind.
Lee Minho
Lee Minho is not so fortunate when it comes to wealth and his family. He avoids getting too close to people in the event they turn their backs on him. He got put in the school because it was the only one that he lived close to. Unfortunately, he is one of the only people in the school that is "poor".
Lee Felix
Lee Felix is one of the wealthiest children that go to school. His dad donates money to them every year. Felix believes that bringing a poor student to the school drops the ratings. He makes it his goal to run them out of the school like he always did.
Yang Jeongin
Yang Jeongin is the brother of Han Jisung. He is not as narrow-minded as his brother but also doesn't know how it feels to be poor. He knows what to say and what not to say, also unlike Jisung. He believes class matters but doesn't treat the people that don't have much like trash.
Hwang Hyunjin
Hwang Hyunjin is also a part of the wealthy class. He lives his life on social media. Always recording something or taking a picture. Having his phone in arm's reach at all times keeps him updated on the news about the school. He is the inside scoop.
Seo Changbin
Seo Changbin is in the middle class and is constantly reminded by his fellow peers. He's never going to live it down until he gets wealthy. It's not like they bully him, but they do make fun of him in the way friends should. Changbin has no idea how he ended up being a part of the wealthy friend group but he loves it nonetheless.
Kim Seungmin
Kim Seungmin is the middle-class president that everyone adores for his outgoing personality. He is also very chill and lets a lot of things pass. Although he is kind of a kiss-ass, if you get on his bad side he's going to make your life a living hell. He doesn't act like a leader often and is more of a bystander that watches and chimes in when he needs or wants.
Bang Chan
Bang Chan is also a middle-class president but always seems to forget he is vice. He wants everything to be perfect and takes his job very seriously. He lost to Seungmin so many times that he just settled for vice president. He tries to make Seungmin do the job that he wanted but since he is second in command, he never gets his way.
