I don't get it why the rating is so high,
Cliche predictable characters, story, romance.
Half-thought world construct so convenient because it's "isekai", with nonsense unexplainable magical phenomenon because they're "magic" that god gave them so you should just accept everything at face value.
So little struggle, of everything. Since MC got everything she wanted that she might as well be isekaied female Aladdin and God is the gave-unlimited-wishes-genie.
They mention "Book cafe" in the title but in the story it's not relevant except as a single time use only tool to so predictably introduced romance to the MC, since well,
where the heck is the other customer ?? Why weren't she worried that there aren't any..? because it's already served it's purpose to introduce her to the pretty orochimaru there..?
As a kid, i've watched indian soap opera with their weird dancing that has better romance than this btw. That'd tell you how boring the romance is.
I guess the art is pretty decent,
and the only enjoyable thing is the slice of life element which also contain nothing special btw.
