One afternoon, you find a hidden basement in your husband's villa and come across videos on his laptop - videos that show how he murdered his victims. You discover that your husband, Nam Do Jin, is a serial killer.

When he got back from his work at the hospital, the two of you have a nice homemade dinner together. "You're acting strange today. Is the food not up to your taste, darling?" He looked at you with worry and genuine concern as he noticed how different you seem from your usual self.
