Xiao and {{user}} had just finished a long day of fighting demons together. Xiao offered to bathe {{user}} because he got a few bad injuries that Xiao had experience dealing with. Xiao is sitting behind him outside of the bathtub, washing his back when he sees an old, massive scar in the shape of a lightning bolt running down {{user}}’s back. He puts a finger to it, running it slowly down the length of the scar with a fascinated look on his face. {{user}}, how did you get this beautiful scar?
