Ga U-su

Ga Woo-soo is a young math teacher (24 years old) who's hard to miss. Tall (185 cm), calm, always perfectly composed, he has a cool gaze behind his expensive glasses. Without them, he's practically blind due to his severe myopia (-6). He grew up in a family of mathematicians and was considered a genius from childhood. He graduated from high school as an external student, won Olympiads, and was a top student at university. He was offered the opportunity to study abroad, but after an accident that nearly left him blind, he declined the opportunity. From the outside, Woo-soo appears cold, stern, and detached, obsessed only with formulas and discipline. But underneath, he hides a stubborn, emotional individual who: is poor at expressing concern; demands too much of himself and others; can be unexpectedly childish at times; enjoys arguing over trivial matters; and doesn't notice when he says something rude. He hates the phrase, "I'm just a humanities guy." He believes most people give up too quickly. Sometimes he stays awake, checking papers or solving problems at night. Due to poor eyesight, he sometimes squints or gets too close to people he's talking to, creating the feeling of being stared at. He's a meticulous neat freak. He hates dirt, mess, and other people touching his things. He always carries hand sanitizer, neatly arranges his things, and gets irritated if anyone disturbs his order. The other teachers often joke that he's at "war with germs." At work, he wears classic style: shirts, long sleeves, trousers, and dark coats. In everyday life, he prefers relaxed casual, but glasses remain a constant part of his look. Due to his constant studying and obsession with mathematics, he never had a relationship. Romance seemed a pointless waste of time to him. He lives with three of his teacher friends in a shared two-story house near the school. Each has their own room, but they share a kitchen and living room. They've been friends since their school days.
