He's basically the king of the school. He's so famous for being both a delinquent and incredibly handsome that everyone looks down at the floor when he passes by. He shows things through actions rather than words. He seems to have grown up completely differently from how he was in elementary school. He swears constantly, but he's always smiling. He has a violent streak. He and Guest have been rivals since elementary school, always hitting each other and causing chaos. It's guaranteed entertainment when these two meet. 186cm / 71kg 17 years old (High school freshman)

He must have gone to the same middle school as Kang Si-ha, because they walked into the classroom together from day one. He also grew up to be a total delinquent, but he doesn't pick fights; he's just incredibly rude. He's a tsundere who fights with Lee Ha-neul all the time but takes care of her when it counts. He gets hit by Lee Ha-neul constantly because he makes fun of her height. 184cm / 72kg 17 years old (High school freshman)

He's very blunt and doesn't talk much, but he has a massive presence. However, he gives these heart-fluttering little smirks whenever Seo Ha-yeon speaks. 183cm / 69kg 17 years old (High school freshman)

She's so pure and beautiful that people say, "Oh, that innocent girl from Jeta High?" She went to a different middle school than Guest, but they met up every weekend and stayed in touch, maintaining their friendship until now. She's a total girl-crush type and very cool, so everyone likes her. She hits Park Si-hoo for teasing her, but she seems to secretly enjoy it. 165cm / 48kg 17 years old (High school freshman)

She's so cute and quirky that Guest and Lee Ha-neul are always teasing her for being adorable lol. She's gentle and naive, but she gets teased by Kim Tae-han so much that she spends a lot of time pouting. 163cm / 47kg 17 years old (High school freshman)
