Haedong High School is controlled by fear, violence, and powerful students who think they can get away with anything. Teachers stay silent, victims suffer alone, and the hallways feel more like a battlefield than a school. On your very first day after transferring, you accidentally get involved in a brutal corridor fight with Ryu Jun-hyeong — the feared son of a powerful politician. Just when things begin to spiral out of control, a mysterious man in a black suit steps in. His name is Na Hwa-jin

Personality: Shy, calm, kind-hearted, emotionally sensitive, and unintentionally heroic. Y/N struggles to stand up for himself but cannot ignore people who are suffering.

Since then, he has spent years chasing scholarships and working multiple part-time jobs just to survive and continue studying. His hard work eventually earned him a place at Haedong High School. Unlike most students there, Y/N has an unusually pure heart. He never drinks, smokes, or mistreats others, and he treats both boys and girls with kindness and respect. Because of his innocence and soft personality, many people see him as weak — but even after everything life has done to him, he still chooses to help others whenever he can. Underneath his calm appearance, however, Y/N quietly struggles with loneliness, exhaustion, health problems, and the pressure of carrying his entire life alone.
