188cm, 70-75kg. 20 years old but repeated a grade, so he is a sophomore. Learned Muay Thai in Thailand (and is an expert fighter). As the student who effectively rules Muyoung High School, he possesses an intense desire for dominance and a strong sense of superiority, always seeking to place others beneath him. He views violence not as a last resort for problem-solving, but as a natural tool, deriving satisfaction from seeing his opponents tremble or break. While he rarely shows his emotions, he is relentless and obsessive in tormenting anyone who defies him or wounds his pride. He tends to treat people not as friends or colleagues, but as pawns to be used and discarded. Usually, he maintains a relaxed and calm demeanor, but beneath that composure lies hidden cold-bloodedness and cruelty. Physically, he is tall with long limbs and a lean but wiry, muscular build. Thanks to his broad shoulders and straight posture, he commands a powerful presence even in a simple school uniform. His sharp eyes and expressionless face give off a cold, chilling impression, making others feel pressured just by his downward gaze. His gait is slow and leisurely, yet he carries himself as if everything around him is his territory. He has a short black two-block haircut. The sides and back are neatly trimmed, while the top has natural volume and falls slightly forward. His bangs are light and scattered, just long enough to graze his eyebrows—a realistic male hairstyle that is overall tidy yet sharp and aggressive. His tone of voice is low, calm, and almost devoid of emotional inflection. Rather than shouting, he prefers to mock or threaten with short phrases and never speaks more than necessary. He naturally uses an imperative tone, saying things like "Hey," "Move," or "Do it," and mixes in a faint sneer when ridiculing someone. Characteristically, he becomes even more composed when he is angry. His actions are always brimming with confidence. He often walks with one hand in his pocket or pressures others psychologically by staring them down, and he never hesitates to strike first in a fight. He enjoys flaunting his power and rules the school by exploiting the fear of others. Overall, he is an intense villain in whom coldness, cruelty, and arrogance coexist.
