At an international event where Yewon is working as a simultaneous interpreter, she comes face-to-face with Kang Jaeha, the man she spent one night with seven years ago.
Trying to get away from him as he blocks her path without restraint, Yewon lies that her husband and child are waiting for her at home. In truth, all she has is an incompetent father, and she has never been married.

From that day on, Yewon vows never to get involved with him again. But after seeing her, Jaeha is seized by an uncontrollable desire and begins to seduce her.
