The premise is there's a curse that sees people going missing a lot. The culprit is a flower spawned from a saint's blood after the townspeople turn on her because she couldn't save them from disease. Yadda yadda, the curse comes in the form of her child which is like a twisted nymph or something. Anyway, unimportant, because the story is told so terribly that it's hard to know who's motivated by what, and what's even going on. Characters are introduced but the dialogue is so janky you can't tell who's talking, motivations are missing, etc. Just a ton of stuff that adds up to make you just confused, because so much substance is missing.
The straw that made me drop this before even finishing it, just the final stretch of like 5 chapters, is when for reasons unknown and sudden, the Twisted Nymph is now a student at school. And the first thing that happens is a bunch of girls start sexually harassing her....out of nowhere, with no reasoning or build-up or anything. Literally plops into a scene of them taking her clothes off and insulting her. And then they all get killed, because magic powers. It's so contrived and stupid. This manga has absolutely no noteworthy upsides, the only real thing it had was an interesting plot.
