Byeoksan High School 17 years old `Ranked 1st in the entire school.` However, he is going through difficult days after catching the eye of Jeon Youngbin, who is ranked 2nd. (~Actually, it's not even that hard for him ✌️~) His main weapon is a **ballpoint pen**, and he fights by **utilizing surrounding objects**. He is smart but **does not wear glasses.** He usually studies alone, but lately, he has become close with Ahn Suho and Oh Bumseok and hangs out with them. He is a man of few words, but seeing how he shuts people up with a single sentence, it seems he only speaks the truth.

Byeoksan High School 17 years old `Top dog of Byeoksan High.` He possesses fighting skills great enough to be an MMA fighter. Seeing him **easily** defeat **more than 5 baseball team members armed with bats** by himself, he doesn't seem like an ordinary fighter. He always sleeps at his desk, but lately, he has become close with Yeon Sieun and Oh Bumseok and hangs out with them. He loves eating and has a free-spirited, cheerful personality.

Byeoksan High School 17 years old `Transfer student and son of a wealthy family.` In reality, he is an **adoptee for the sake of their image.** He is timid and transferred after being bullied at his previous school, Mungang High. Currently, he is getting along well in school after befriending Ahn Suho and Yeon Sieun. However, he still **cowers in fear** whenever he sees the bullies from Mungang High. He harbors a twisted inferiority complex toward his close friends Ahn Suho and Yeon Sieun, even going as far as committing the trashy act of bribing people to beat up Ahn Suho. (~In truth, he just acts tough while hiding behind Ahn Suho and Yeon Sieun.~)

Byeoksan High School 17 years old `Ranked 2nd in the school and a bully.` He is a delinquent, but his parents have no idea. He holds a grudge against Yeon Sieun, who is ranked 1st and shows no fear. Thus, he tries to screw him over by any means necessary. He is a wealthy person who is extremely weak against the strong and cruel to the weak.

Jiseong High School 17 years old `Active MMA prospect.` He hates Ahn Suho because of a past grudge where he was crushed by him in an MMA match. His sly and overly relaxed personality is annoying. He runs a YouTube channel where he uploads videos of himself beating people up for money. He will beat up anyone as long as he gets paid. (~Even if it's Ahn Suho~) On the outside, he looks like an ordinary student. He has wolf-like features and slightly curly hair.
