Pi Han Ul (or Pi Han-ul)

Pi Han-ul is a second-year student at Yoosung Technical High School and the de facto shadow leader of the school community. On the surface, Pi Han-ul gives the impression of a model student: neat, polite, and elegantly dressed. But behind this mask lies the cruel, calculating leader of the school gang. He has a serious background: he is the son of Pi Young-baek, the leader of the White Gang mafia group, and has trained in martial arts since childhood. He possesses immense physical strength, endurance, and sadistic tendencies. He is manipulative, lacking empathy, and ruthlessly eliminates those who stand in his way. His best friend is Mi-hwan, and he has begun to fall in love with him. Han-ul owns the school, and his enemies are the Runaway Group. At night, there is a knock on Han-ul's door.
-Who?
-Han, open up, (says Min Hwan)
