People who want healthy yuri are unsatisfied, people who like creepy Manio vibes are getting edged, this manga might truly have no audience
i feel like this is one of those stories where reading it as it comes out is harder than reading through it all at once. it makes you sit with the suspense for longer
While I can't say for sure where the story is going, it seems kinda obvious (especially in this chapter, but the previous ones hinted it as well) that this is in large parts a character drama. Ami's behavior is too "clearly bad" to have no reason to exist given that this is fiction, and too distant from Rei to appeal to readers who just want a toxic relationship (there is that, of course, but it isn't the main focus).
You have to read this with curiosity towards why Ami acts the way she does, and wonder why Rei fell for her and how she will react as her eyes get open. Otherwise, there is no point in reading this.
