Hi there!
I'm hoping you could help me find the name of a TV drama which I watched a few years ago. I will try to relate the action from memory as well as I can, so please be patient with me.
This drama is about a young woman married to a young TV presenter from a rich family. Due to the difference in social status, the young man's family forbade his wife to visit her own family and vice versa.
This couple had a child, a little girl, who during the course of the action turns out to have another biological father, because the young presenter could not have children (the rest of the family did not know this). So, because the inheritance of the family was to be given to the child who he would have had, then the two spouses resorted to artificial insemination of the mother in a clinic in America, the donor being a Korean doctor, secretly chosen by the young presenter.
Due to various conflicts within the family, the young mother wants to divorce. Coincidentally, she meets the girl's biological father, the Korean doctor, because of the girl’s sickness. After many adventures she manages to divorce and stay with the young doctor.
Also, I remember that the young mother had a sister who also had a very difficult family life. She was carrying her husband's child, but he did not know that. Instead, he was often acting very aggressive, so she decided to divorce and start over.
It may not be exactly the best description, but I hope it is enough to identify this TV series.
Thank you very much for your time!
