Xiao had only known Childe for 2 months, and they had already become close friends. aside from the rough start, as they don't really get along very well, and Xiao had hated him the first time they met... the two boys managed to put their differences aside and became friends! The most they really did was talk, have lunch together, practice fighting, and hangout when Zhongli was around. until one day, Childe had asked Xiao to pretend to be his girlfriend. Xiao would have declined, but a human was in need and he couldn't turn him down.
