I think that's part of the reason Yun Ru is pushed to commit suicide. I personally agree that Li Ziwei (even though he's great and I love him) went way too far when he told Yunru "please don't use Huang Yuxuan's expression to look at me" or something. Had he known Yunru was in a fragile state of mind I'm sure he wouldn't have said that, but it just goes to show that your every word can have a drastic impact on someone.
But also, I was kind of upset that Chen Yunru felt the need to have to pretend to be Huang Yuxuan just to earn the love of the people besides her. There are people in that world who love her just as she is (Mo Junjie especially), and it made me sad that she couldn't see that.
