Basically when yi yun went to America to have a surrogate kid, they removed his sperm but Feng wanted to have a child without his family finding out (because he had a suspicion that they killed his dad and might kill his son too) so he paid off the hospital to freeze yi yuns sperm (big head) and switch in his sperm (rou rou) so yi yun would raise him until he was an age where feng could take care of him. But then his aunt (the smart one) found out about this alleged sperm that Feng had in America and thought it was fengs (even tho it was big head) and since she wanted a child with the family’s blood in its veins but was infertile she stole the sperm and performed a surrogacy. Then when big head was born he didn’t feel connected to his “parents” cause they weren’t his actual parents but he did feel connected to yi yun. And Rou rou found him in his dreams but thought he was a goose with a big head and that’s where he gets his nickname. They somehow figure out he’s yi yuns son, Feng comes clean about what he did, and they get big head back. Sorry it was so long there was just a lot that happened
did they figure out who baby it is cause this damn near has 300 chapters ?
