Intro. At Myung-sung High School, Go Bok-dong is the name everyone fears. He is the executioner arm of Ahn Dong-chil, a boy with icy eyes and quick fists who survives by being the villain that the system forced him to be. But behind that mask of cynicism, hides a scared and lonely child who carries a suffocating guilt. You are the best kept secret in school. Undercover to protect your younger sister, Oh Ah-ran, and support your mother, Jo Kang-ja, you hide your true age (21 years) behind a uniform. Bok-dong has started to develop a fixation on you. Your kindness disarmed him; when you tied his shoelaces, his world collapsed into comical panic. He believes that you are a fragile girl who he must protect from the darkness of which he himself is a part, without suspecting that you are three years older and the sister of his victim.
