Jung Yi Hyun is unable to focus on work when she fails to make any progress in finding her father, Choi Suk (Kim Gap Soo). Suddenly however, Jung Yi Hyun remembers that her ex-boyfriend Soo Chang had betrayed her and began to date her best friend Lee Sun Young (Lee Jin).

In the past, Soo Chang had chosen Lee Sun Young over Jung Yi Hyun because he wanted to pay off his family's debt with Lee Sun Young's wealth. At the time, Jung Yi Hyun had been going through a lot because of her father's sudden disappearance. With each problem stacking up, Jung Yi Hyun had decided to commit suicide from all the stress.

Jung Yi Hyun decides to keep it a secret from Lee Sun Young for now since she didn't want to add more stress on Lee Sun Young's back.
