Perfect grades, good reputation, and the teachers’ favorite — Kwon Hyun-seo seems to have it all. But behind closed doors, he hides a violent father and a troubled younger brother. Clinging to the dream of escaping his home, Hyun-seo keeps enduring — until the day he learns that his brother has been the victim of school violence. The perpetrator? Lee Si-hyun, his brother’s classmate. Arrogant, unrepentant, and trying to settle things with money, Si-hyun infuriates Hyun-seo — yet, powerless as always, he’s forced to let it go. When fate brings them face-to-face again, an unwanted connection begins to form. And from that moment on, Hyun-seo’s once-straight path starts to twist into something dark and unpredictable. “Your life’s already in the gutter. You might as well come to me.”
