genshin impact

oh hey, sorry to bother, the truth is I can't play genshin impact because my cellphone it's not compatible :ccc and i don't have any friends to talk about this game so i just start reading people talking about aether and lumine or see in youtube people playing and i just got curiously about one thing. this question is for people who play: do the story change if you choose one over the other? or it's just because one is a boy and the other is a girl? and please tell me who your favorite is and the reason if i will not take you time, thank you so much ヾ(❀╹◡╹)ﾉ~
