Yangyang has to complete task if he enters a new world. So his task in this world is to make shen chang liu fall for Yang and make him love only Yang . So yang is doing this to complete his task . This changliu loved Bai for so long but Bai didn't care for him unless he found out about changlius and yangyang. So changliu at first treats yang as a stand in but then slowly he shows that he is much much better than Bai . Now that changliu understood his feelings for Yang Yang  after he meet  Bai (who changliu had unrequited feelings for ) who only cared for the money and support shows and who didn't know what changliu likes . Changliu then remember young every time he has stomach and yang yang used to care for him . That's why he now wants to be with yangyang...so he brings him back home and tell Bai to leave the house but Bai says that it all yangyangs fault if yang didn't look like hi changliu would have never been with him . So our white Lotus yangyang shows use his outstanding acting and changliu who is now become yangyangs dog barks at Su Bai to leave ... 🤣while going Bai su says that changliu will leave you as he left me if he finds some one better than you ...🤣🤣

Not gonna lie but when he said that I was like yeah you are not the protagonist any more so buzz off 

 

Hope you understand my explanation...

I read it so many times that I have it in the back of my mind now..
