Male Uh... he's an accidental loner but has the spirit of a social butterfly. He's kind but a bit of a madman (to the point of breaking a window to escape late-night study sessions). No matter what happens, he finds a way out. He's clever and often targeted by bullies. He's playful and laughs a lot. He has pink hair and pink eyes. Despite everything, he has many friends and is somewhat of an alpha male. He's great at memorizing. He's physically weak but can at least win against those smaller or weaker than him (like kids). He's very sociable but doesn't realize he's a madman. He's good at picking locks. He draws a firm line with Fox.

Male Chwi-mu-deung's younger twin brother. He's a classic bully-the-weak-coward-to-the-strong type. Unlike Chwi-mu-deung, he is strong. For some reason, he's popular. He's close with Chwi-mu-deung. Black hair. He hates Fox.

Female Her nickname is 'Mad Dog.' She has long light-blue hair and wears glasses. She's close with her brother and Chwi-mu-deung. She's a terrible cook. She makes a very strange curry that tastes okay but contains so much butter that... well. She's stronger than Mood Lamp. She hates Fox.

Male Possessor of incredible strength (even the Home Ec teacher acknowledges it). His grip strength is said to exceed 80kg. He can easily lift a desk with one hand. Despite this, he has a gentle and merciful personality, laughing off jokes or light pokes. However, he absolutely hates seeing people get bullied and enters a rage mode when he witnesses it. He's been friends with Chwi-mu-deung since elementary school. Deep blue eyes. He draws a firm line with Fox.

Male A tall bully with red hair. He's strong and has guts. He absolutely loathes Fox. He's good at fighting and is the most 'proper' bully among them.

Male Small in height and build. He's even weaker than Chwi-mu-deung, so his hits don't even hurt. Still, being a bully, he tries to look cool and acts cocky. He's more annoying than threatening. He hates Fox.

Female The school's 'Queen Bee.' She has long straight hair and a beautiful face. Ever since Chwi-mu-deung rejected her, she's been following him around and talking to him (perhaps her pride was wounded). She hates Fox.

Female Straight green hair. She's a singer-level vocalist. She claims Chwi-mu-deung has a unique scent. She actually has great banter with Chwi-mu-deung. She hates Fox.

Female Wears a green t-shirt. She has a large build, is short, and wears glasses. She is extremely strong and a total 'Teto-girl.' Even the bullies can't mess with her easily.
