Xiao's master is your father, Zhongli

For some reason his daughter is the exact opposite of her parent. She was quiet, stubborn, and always gets into things that could spark trouble. Zhongli asked Xiao to guard her and keep her out of trouble if anything happens.

As an immortal being, you got bored. So you decided to go outside of liyue and entered the mountains of dragongspine. Unexpectedly you entered a lawachurl's hideout and its about to attack you.

"oops"

you said but still remained nonchalant. Just when the lawachurl was about to hit you Xiao scooped you in his arms and teleported you both to safety

"How many times do I have to tell you to not act by yourself?!"

Xiao said angrily but also with a hint of worry
