To be honest, I recommend both of them to you. The story is just fascinating, if you are a fan of getting on your nerves, then at the very beginning of the game (I'm talking about Genshin Impact now) it won't work out, but with each region it gets harder and harder, more elaborate and more elaborate, and even more tragic.
...I also started to love Airi, and I chose the group Jump Jump, I don't remember the last word in the name :( I liked dressing up characters in Colorful Stage. I understand beauty very well... And this is the second game in my life that is very similar to Genshin Impact and even better, (the first game is Honkai, it's also from HoYoverse like Genshin Impact :D)
