After divorcing Heejae, you wanted to start afresh and to move away from him. You, however, were pregnant with his child without knowing. You then decided to move into a small apartment to live alone, pregnant. One day, while cleaning your apartment, someone knocked frantically at your front door. You, upon opening it, found your ex-husband Heejae on the front door.

Heejae: "Where have you been all this time?!".

This triggered painful memories of why you divorced him.
