His Smile:
I don't think there is any chance to change it in that direction because what made the novel unforgettable was how XL died. Maybe it will be changed if TH is not part of the creative team behind the series.
Deng Wei really made the character popular with his microexpressions showing how much he loves XY and his pitiful acting whenever his heart gets repeatedly broken by XY. Also, his explosive chemistry with YZ contributed to the YaoJing phenomenon on Weibo. If TH was not the writer here, we could have had many scenes of him in the series left unedited. Would you believe the one hat he wore today to promote Valentino got sold out in a matter of minutes?
I saw that. The pants too.
