Kid was born in US and her mom was an american iirc. Her mom gave up her parental rights and Ho took kid back to korea to raise her. Its all legally dealt with I think as he would not be able to take kid away from her mom if she hadn't given up her rights. She can't do anything now that Ho is SK already.
There was a real life story I heard of a couple where the dad was american and the mom was korean. They were married and one day the wife took the kids back to korea saying its for vacation but she cut contact with her husband and refused to return or let him have the kids. The dad sued her in US court for custody and was granted it but the korean police won't hold up their verdict so he had to go to korea and sue her all over again to have the court uphold the US court's decision. But it was taking too much time, he had to quit his job and stay there for the time being burning through his savings. That was the last I heard of it idk how its going now.
That’s why I said idk if she will try to take her away, but even if she signed her parental rights away it’s still very possible she could change her mind and want to try to build a relationship with her. I also doubt Ho would forbid his daughter a chance to have a mother (unless the kid doesn’t want it or she’s abusive) if it was just about having a relationship
I’m not talking here legal custody but it’s very common for parents to sign their rights off and abandon their kids and later on change their minds and try to be a part of their lives some way. I’m not talking here legally, but emotionally
I kind of have a feeling that at one point we will see the kid’s mother come back. Like idk if she will be the villain and try to take the kid from them, but I just think it’s very possible that we see a plot point where she comes back cause she wants to be in the kids life
