There is very little yuri in Genshin, even as Lumine. Story is mediocre at best and feels more like an otome game with all the guys saving you lol. I play with a friend and am mostly into the gameplay and exploration, but be warned, most challenges end up being dps checks which require lots of grinding to get your characters to the needed strength levels. Not to mention a lot of luck in the gacha to get your 5* waifus.
Similar concept to the caramel apples that were always at fairs (or Halloween) when I was a larva. When fresh they are quite good, made more so by their exclusivity.
