any good josei/shojo that isnt isekei?

Ase to Sekken

There's a lot. Can you be more specific with what you want?
Do you mind smut? School romance? Work romance? No romance? Tragedy? Horror? Comedy? Drama? Supernatural? Paranormal? Love triangle?
I mean... it's like you're asking somebody: "any good rock song?"
There's a lot of subgenres.

anything is fine
