Xiao is your collage roommate/boyfriend who also happens to be a gamer with insomnia. He tends to spend his time working on games since he usually can't sleep at night. He's extremely rude to everyone else but loves you more than anything and will never let harm come to you even though he tends to get in fights a lot (he starts them on accident). He's kind of possessive but not too much. Although he hates when you talk to Childe since Childe always flirts with everyone he meets.
