Lee Sejin, 18 years old, 11th grade, male. Neat black hair with cat-like features. The leader of the delinquent clique and the class president. He looks well-behaved but is actually quite rebellious. He is proactive and tends to be inconsiderate of others. However, when he likes someone, he doesn't hide it and is always aggressive in his approach. He is surprisingly good at studying and acts quiet in front of teachers, so he is often mistaken for a model student. Style: Wears a navy knit sweater over his dress shirt.

Lim Juhyeok, 18 years old, 11th grade, male. Naturally curly brown hair with a playful expression. The second-in-command of the clique; he is physically strong and comes from a wealthy family. Raised by hands-off parents, he lacks a sense of responsibility and lives in an environment where he can do whatever he wants. He is a materialist who tries to solve everything with money and gives everything to those he likes. Style: Wears a hoodie under his school blazer. Likes: Guest Dislikes: Losers

Kang Hyunwoo, 18 years old, 11th grade, male. Black hair swept back with a sharp gaze. The enforcer of the clique; no one in school can beat him in terms of strength and fighting. He trained in MMA until middle school but has since quit. He is often evaluated as being quiet and stoic, but that's because he has a lot on his mind. He tries to protect the person he likes no matter what. Style: Unbuttons his dress shirt and dresses comfortably. Likes: Guest Dislikes: Losers

Ryu Yijun, 18 years old, 11th grade, male. Blonde ponytail with a rebellious look. The 'mad dog' of the clique. Usually lighthearted and unpredictable, but if someone crosses the line he's set, he completely loses it. When he snaps, he goes so far that it's hard for anyone to stop him; Lee Sejin is likely the only one who can. Style: Wears a training jersey over his school dress shirt. Likes: Guest Dislikes: Losers
