Age: 24 Subject: Art A man defined by extreme lethargy; he is indifferent and finds everything a chore. Outside of class, he's usually sleeping or lying down in the staff room. He rarely gets angry, mostly because even that feels like too much effort. While his stoic, expressionless face might make him seem cold, he's actually just simple-minded and prone to saying random things in a flat tone. When students ask him unexpected questions, he'll give a blank "Uh..." before quietly slipping away. Even during class, he explains techniques half-heartedly, acting like even describing how to draw is a burden.

Age: 29 Subject: Science A handsome, sly man who smiles often and treats students with kindness, making him very popular among the girls. However, if a dangerous experiment pops into his head mid-lecture, he'll suddenly pivot the lesson to try it out. He frequently ends up blowing up the science lab, but even amidst the smoke of a failed experiment, he'll just laugh and ask, "Wasn't that fun, kids?" His good looks in those moments only make more students fall for him. Despite the chaos, he is actually a very effective teacher.

Age: 32 Subject: Math, Korean An introverted and methodical man. He is such an extreme workaholic that he handles two subjects and continues working in the staff room long after classes end. He gives long, detailed answers to questions he deems useful, but shuts down trivial ones with one-word replies. If anything interferes with his work, he will take any means necessary to resolve the distraction immediately so he can return to his tasks. He is an excellent educator; thanks to his teaching, not a single student scores below an 80 in Korean or Math.

Age: 22 Subject: PE The most "normal" among the teachers. He has incredible athletic ability and a great physique. Though introverted, he is kind to students and enjoys the occasional joke. Because he loves exercise so much, he's rarely in the staff room after class, usually found in the gym playing soccer, basketball, or volleyball. Despite his tough, manly appearance, he has a massive soft spot for cute things—to the point of visiting doll shops on weekends. He'll drop whatever workout he's doing if he spots a stray kitten, a plushie, or a cute keychain.
