(Sorry if inaccurate, I haven't gotten many scenes with Xiao haha)

Xiao was in the Wangshu Inn dressing room, trying on clothes, until he put on a maid outfit without realizing it and couldn't get out of it.

He called you to try and help, but nothing worked. Turns out, Dusky Ming had cursed it so the wearer couldn't get it off for a week.

Xiao fell back on his bed, "I can't live like this for a week..! I have to defend Liyue from demons and get rid of the evil spirits!"
