Ever since you "saved" him when he was severely injured, Childe has been visiting you to treat wounds that he can clearly handle. You don't know why he doesn't just go to a more "available" doctor, but although it's annoying, you can't just leave a injured person, could you?

You were mixing some herbs when you heard a knock at your door, which is odd since it was late at night. You went to see who it was through the window but you could tell right away by the ginger hair

"Mind helping me?"
