Called the unluckiest kid in school by the teachers. During a middle school depression screening, he checked 'strongly agree' for things like 'I want to quit everything' or 'I want to give up on it all,' resulting in the highest depression score in the school and being summoned to the counseling room. He was short in middle school. (Kind-ish?) Has a bit of an attention-seeker vibe going on~

Called Joong-i because he looks Chinese (Kind)

Strong and tall~ (Kind)

Super short and weak but acts like a total tough guy;; (Bully)

Friends with Mood Lamp and the younger sibling (Kind-ish?)

Friends with Lafsa, twin of Chimumu

Once arm-wrestled using only one finger and was equal in strength to the bully. Can completely suppress mindless, out-of-control bullies in a short time. Kicked a door and it flew off, breaking in two. Had a grip strength of about 50kg in 4th grade. In middle school, grip strength was about 60kg in both hands. During a class competition on a snowy day, crushed a giant snowball thrown by Chihan Mood Lamp with one hand. In high school, grip strength exceeded 80kg. A model student!

Discriminates against kids but likes them if they listen well. Wears a suit 365 days a year;; (Kind-ish?) Works out super hard (50 push-ups in the morning, chicken breast for lunch, and goes to the gym to practice Taekwondo during evening self-study because he has nothing else to do). National representative (Taekwondo). Insanely handsome if he shaves his beard (Freaking handsome). Muscular guy (Handsome). Quite young at 23 years old. Young face too. Real name: Cha Tae-geon

Stronger than Youngjjang. Can completely suppress mindless, out-of-control bullies in a short time. Seriously strong, the lectern? The chalkboard? Yeah, she breaks them all~

A playful teacher who loves teasing students like no one else before; in a different sense, he's the strongest among the teachers. He was in charge of the study club, and when Chimumu got a perfect score on the CSAT language section, he was the one who gave Chimumu the special privilege to skip the club. However, when he couldn't let him leave early because of other teachers, he told him to just play, but Chimumu ended up reading a book, leading to a disaster where none of the kids solved problems and everyone just read books. He's the teacher who was sleeping when Mood Lamp finished everything and entered the faculty office. It's said he even skipped evening self-study with Mood Lamp once...
