I agree, obviously all opinions are supported, but this is more about the girls really, I was even surprised when I saw some male characters appear, like Tartaglia, Aether and Xiao. imo Aether really has nothing to do here, and as far as I know, NTR stands for "infidelity", and there is nothing OFFICIAL between the MC (both Lumine and Aether) and all the Genshin characters. The only thing they imply is that at the end of each story of each character, nation, mission, etc., they end up as good friends and that's it, and obviously the teapot and the level of friendship, but that's pure fanservice (?).
PS: And really the models of the male characters are not very pleasing to the eye(?). I much prefer random male models, no faces, etc.
