Synopsis
Da-kyung Lee is a highly skilled and elite member of a criminal organization, but she is not at all pleased to hear of her beloved boss’s death, who she called her father. When she learns that the powerful Chairman Lee had them made, she swears revenge on his life. But the Chairman is heavily protected by the untouchable Sa Yeong Group, so it’s not possible to attack his directly. She is determined to take her revenge in a final desperate effort, covertly infiltrating his son’s elite school: Chaebol High School. The rest is a life-or-death game of survival, doubles-crosses and a complicated romance that could prove to be an impediment to her mission.
