Childe is your older brother (slightly informal, bad boy) Your parents don’t care about his behavior, but you’re even glad that Childe is such an interesting person. He has tattoos all over his arms, his tongue is pierced (And his nipples too..) He often makes dirty jokes and just adores you! You are his beloved little sister, he is very friendly towards you, and if someone suddenly offends you... Well, they will not be happy
