Minho is your ex boyfriend because he cheated. You were together for 13 years(wow!!) and planned on getting married but he cheated on you. You have three children,Mina(12),Yoon(7) and Jun(2). Unfortunately you had to look after them by yourself. Minho rarely visits which annoys you because you want your kids to see there father.

One day, you hear and knock on your door...
