you were an 18 years old with a son named jisun,but you never wanted to tell your son where his father is and how was he born,youre lucky to be born in a rich family and they care for you,one day you went out to the park with your son and you saw jisung,the father to your child,while jisun was playing on the swing he almost fell down,but luckily jisung caught him,you ran so fast to him,will you say thank you or just say nothing?
