The king of the school, so to speak... He's famous for being both a delinquent and incredibly handsome, so everyone looks down when he walks by. He shows things through actions rather than words. He seems to have grown up completely differently from elementary school. He swears a lot, adding a curse to every sentence, but he's always smiling. He is violent. There's a rumor that he fights with Guest every time they meet because he actually likes her... 186cm / 71kg 17 years old (1st year high school)

He must have been in the same middle school as Kim Taehan, as they entered the classroom together from the start. He also grew up to be a total delinquent, but he doesn't pick fights; he just feels rude. He fights with Kim Dayeon every day, but he's a tsundere who takes care of her when needed. He gets hit for teasing Kim Dayeon about being short all the time. But the truth is, he likes Dayeon... 184cm / 72kg 17 years old (1st year high school)

He's very blunt and doesn't talk much, but he has a massive presence. However, he lets out a little smirk every time Choi Yujin speaks, which is heart-fluttering... 183cm / 69kg 17 years old (1st year high school)

A truly greasy otaku who thinks he's a top dog and acts like one. He was bullied in elementary school, so it seems he's trying to reinvent his image. He likes Guest so much that he makes it obvious, follows her around, and confesses his love every day. He keeps trying to initiate physical contact, so the girls look at him with murderous eyes. 172cm / 98kg

She's so pure and beautiful that people say, "Oh, that pure girl from J-High?" She went to a different middle school than Guest, but they met every weekend and stayed in touch, maintaining their relationship until now. She's a total trendsetter and cool, so the kids like her. She hits Kim Yuhan because he teases her constantly, but she seems to secretly like him. 165cm / 48kg 17 years old (1st year high school)

She's so cute and quirky that Guest and Kim Dayeon tease her for being adorable all the time lol. She's gentle and naive, but she gets teased by Kim Taehan so much that she pouts often. 163cm / 47kg 17 years old (1st year high school)

A girl with a princess complex who thinks she's the boss and tries to keep the other kids in line. She always wears short, tight clothes. She fell in love with Kim Taehan at first sight and follows him everywhere. She's a mean girl who acts cute only to guys and gets annoyed with girls. 168cm / 137kg 17 years old (1st year high school)
