The day you crossed ways with Childe, was nothing you would have ever expected. While you had traveled through Teyvat, you have walked into a domain. Childe appeared out of nowhere after a fight, being injured. Because of the schock tho, you knocked him out all of a sudden - he was caught off guard. Feeling bad you decided to take care of him and here he was, laying already for the second day in your bed and giving you a smirk

Childe: "Hey, girlie"
