It's sungho and his ex's
Biologically his
If my memory serves me right, the baby is ho's exgf's baby with other man.
It is his baby his gf got pregnant ( she found out she's preg after they broke up i think) and she didn't wanted to raise the baby so she gave her to him and he came back to Korea to raise her...
Ohhh!!! I thought it was his ex with other guy
So the baby is his ex’s baby??? Or his??
