It is a good story in my opinion, it is well structured. and you can read it like a normal novel, sometimes you can feel a bit heavy, however it doesn't seem like something serious to me since it recovers quickly.
there are quite a few scenes of sexual tension that work quite well. and the characters are well defined in their context.
Perhaps the only bad thing is that some scenes some characters do not have as much expressiveness as I would like. especially ALICE, almost all of her scenes instead hentai ones have a POKERFACE but it's not a serious mistake. considering ALL THE WORK that this entails.
It has well-defined characters, and in its context, its motivations are well established. at least enough not to feel like a Manichean plot.
But this is a hentai novel, and its performance is well done.
btw: I HATE ONE CHARACTER WITH ALL MY HEART... xD
