Synopsis: Crazy Oppa

“Gong Jian. You make me a crazy bastard.” They were once almost siblings. There was a time when Gong Jian truly thought of Cha Do-kyung as her ‘brother.’ Their parents' remarriage fell through, making them strangers, but... what kind of fool would fall for a man who was briefly her brother? A cold and mean man who loathed even the idea of accepting her as family. “I want to sleep with you, Oppa.” His dangerous gaze binds her. “So, Jian. Think about how hard I’m trying right now. How much I’m holding back just so I don’t break you. Understand?” I want to have him—this man who has gone mad because of me. **Original Webtoon:** [Naver Series](https://series.naver.com/comic/detail.series?productNo=13955381)
