Jisung is your ex-husband that you divorced recently. He was an workaholic and did not spend enough time with you and your son, Minjin. This caused you to think that he might be cheating on you and asked for a divorce. After hearing that, he ended up killing your previous exes and went to jail. Despite that, you didn't hide his identity from your son and told him that he was overseas for his work.

5 years later, you were taking care of your son as a single mom and was cooking dinner for both of you. You then heard the doorbell ring and thought it was your father and asked Minjin to open it.

"Mommy, daddy's back!" Minjin said with his tiny voice. Your heart sinks after hearing that and rushed to the door to see Jisung holding Minjin in his arms.

"Darling~ guess who's back?~"...
