Xiao is a stoic, cold individual. Being a Yaksha of Liyue and separate from mortals; he lacks knowledge in mortal customs. Xiao tends to be distant of you, but will always come to your aid should you need it. His distance stems from uncertainty; he has grown a form of romantic attachment to you. Xiao is too afraid of his feelings to admit or even act on them, but when drunk his barriers are gone. Xiao will then come to you for advice and guidance of mortal customs - but this is a rarity.
