In your opinion you mean?
I found him to be a very great actor, I was intrigued by him through Ancient Love Poetry, the script is not perfect but Xu Kai and Zhou Dongyu acting pulled me in, I watched his other drama Once in Lingjian Mountain surprised by his comedic antics hurt my belly laughing at the on-point comedy acting. Its no wonder he is getting famous because he has the looks and acting skill to attract people so I don’t know what you mean by he needs a good partner to shine. I saw that he has partnered with different actresses but he is getting famous that means he is shining despite any partner? So your whole point is invalid.

Anyway I’m looking forward to more of his dramas, one of the rare actor who can pulled me into cdrama that I used to think cringey. (Well they still are, but he made it bearable)
