Cheng knows Wowo is his child. As for Wowo, Cheng already told him to call him Daddy. But he is too young to understand this situation and the fact he has two fathers. So - no, Wowo has no idea since he is too young
And yes, Nian knows that Cheng found out the truth since Cheng forced him to admit it.
Omg thanks so much, you're a lifesaver! <3
No problem. <3
Ahh this hasn't updated in a while so I forgot but does Cheng know that Wowo is his child and does Nian know that Cheng knows that Wowo is his child?
