You were recently attacked by monsters left by the essence of dead gods in Liyue, nearly killing you.

You met up with Zhongli in Liyue harbor and told him what happened, and feeling horrible for it, Zhongli sent Xiao to watch over you for a week, for safety.

You tried declining, but he insisted. Now Xiao is boredly following you around, watching carefully as you fight to complete your commissions.

You didn't notice, but he was making sure you didn't have a scratch, and when you got hurt, he immediately stepped in.

Xiao: "Tch.. be more careful."
