Really, if you don't know Russian but decide to learn Russian, I really recommend checking out Max Frei's "Labyrinths of Echo" series (and it's two followup series) once you get comfortable with the language.
It's like isekai into a fantasy world, but that fantasy world is very unique and full of interesting details, the story itself is kind of a magical detective story, but it's not very focused on that, instead it's a lot of talking and eating, and it's comfy and takes it's time to explore the world and characters.
There is an official english and german translations of first book, but not much else, so I don't know if I can recommend those. There is also a good unofficial audiobook in russian with one actor but really good acting that the voices from it became canon in my head (forgot the author though, oops).
