wriochi so delicious i don't know why more people didn't pounce on it. they're extremely funny to me in the sense that you have a guy who could probably benefit from being put on a leash versus a guy whose job literally IS that. but also, the family parallels? childe who was sent to the fatui by his father to 'fix' him, and wrio who came this close to being 'sold' off. both of them having siblings they cherish deeply and yet wrio choosing to leave his behind in the past. childe being someone who hides his violent tendencies from his siblings while wrio being someone who resorted to those tendencies to save his siblings. both of them adopting new roles and being deeply loyal in carrying them out. all this to say they mesh surprisingly well.
