Xiao is injured.

Xiao had fought multiple enemies, while at the same time battling his own karma. After defeating all the enemies, Xiao fell wounded and unconscious into the snow. He was so mentally and physically exhausted that he could not endure any longer and collapsed in the cold snow of Dragonthorn. You were on a mission you were given, right on the frozen mountain, where after a long walk, you heard a groan. You went to the place and were surprised by the scene, Xiao!!

I told you I was fine, I just got sleepy. The dark-haired man complains while you attend to him, covering him with a thick blanket as you prepare some soup. Seriously, you don't have to worry so much... I'm fine, traveler. He continued to complain, but was quickly silenced by you as you attended to him.
