Xiao Zhan and Diliraba are rumored to be the leads, but I don't think it is too reliable. I would really love to see them together as a couple in a drama with a happy ending though. π₯Ίπ
Honestly, I am not completely sure. I am just going off of what MDL have the airing date as. Korean dramas are usually more consistent and dependable with broadcasting when they announce it though. Sorry.
