@mangago please add an Isekai genre so it's easier to find this kind of manga, there are so many now but not all of them have 'isekai' in their name so it would be helpful, since it is indeed a genre of its own by now.
I get that you've read the light novel but I wasn't even looking at topics they were just chilling on the side and now I have info I did not want ┑(￣Д ￣)┍
The first chapter where she initially meets Sakuya and he grabs her lyrics appears to be missing?
Which was very unnerving. The storytelling wasn't nearly as good after that either. I'm not sure if they changed authors but it was disappointing.
It is a novel that they are shortening into a manga novel is better
