@What? Yeah , may b he loved jitae's mother . Because it looked he is in love with her. But when jitae's mom said she will marry him she looked so tired and depressed. May b she got pregnant before marriage and they both came to know about jian's existence. Because when jian and his mother came the father accepted them with open hands even though his wife was pregnant .
@Qiqi I think he was too happy about it, maybe it's just a scene but that dude didn't even show some concern to his pregnant wife. perhaps I read too much manga where one parent especially the father was a cheater or using his wife for her status so my mind fuc*** up
