Well Mu Zichen is a playboy. Wen Yue really loves Mu Zichen from the first time they meet each other, even though wen yue is like a bad girl that likes to drink, go to bars, and play with other boys ( she just want to have fun and nothing serious), she is ready to change all of that because she loves mu zichen. Then when the news that she is pregnant and the father is Mu Zichen, but denies it cuz he dont believe her like I said wen yue is a bad girl and he know that she slept with other men, but wen yue dont do that any more after meeting mu zichen cuz she wants to change for him, and they regularly meet like a date but to mu zichen she just like other women that he had slept in the past so he dont take her seriously. So even knowing thag wen yue is pregnant with his child ( but dont believe), he still meet other women which anger wen yue. Then Xia Ning said to Mu Zichen that if he dont take responsibility she will destroy him ( this is what i remember, if im wrong then please forgive me). Then Mu zichen lives with wen yue in her apartment, and takes responsibility time go on he kind of fall inlove with wen yue. So he said that even though the child is not his he will take responsibility ( i dont remember but it kind of he accepts the child, please correct me if im wrong). But here we come the mastermind behind the kidnapping of the son of xia ning is on the move again thia timw uses mu zichen, wen yue and their child. Wen Yue caught mu zichen talking to a woman infront of their apartment and i think she falls down in the stair ( maybe push by the woman w/c with the mastermind and also the best boy friend of xia ning, the one that is a singer dont remember the name). At that tome wen yue is angry with mu zichen cuz she thinks he didnt change and still dont loves her but dont know that she and mu zichen is being used to cause the mental disorder of xia ning to kick off again by triggering it with the loss of the child which xia ning has a trauma cuz she loss her baby girl ( a twin with the boy). After the miscarriage of wen yue she blames it all to mu zichen and hates him. After that she travels around the world that even xia ning didnt know where she is. I think even before the terrorist attack, she still has fewling for mu zichen but cant forgive him and hate him at dthe same time. That why when mu zichen is hospitalize she wants forgiveness from him not cuz he is hurt by saving her but for all the harsh treatment she did to mu zichen even knowing that mu zichen really wants to be with her and also blames himself for the loss of the child.
