At an international event where she was working as a simultaneous interpreter, Yewon unexpectedly runs into Kang Jaeha, the man she spent a night with seven years ago. Trying to get away from him as he stubbornly blocks her path, Yewon lies, saying that her husband and child are waiting for her at home. In reality, the only “family” she has is her incompetent father, and she has never been married. After that day, Yewon firmly vows never to get involved with Jaeha again. However, upon seeing her, Jae-ha becomes consumed by uncontrollable desire and begins to seduce Yewon.
