If you need something creepy but with fluff, this is the perfect manga. Yanderes are horrifying and so is this one. Obviously a toxic relationship, but that's ok for this story, since that was kinda the main point.
The only thing bothering me is that the seme looks like a 12-year-old kid. I don't think that some mangakas understand the meaning of a cute top. Yuri is cute. But Michiru looks like a fucking kid.
