The characters are really badly written. The story seems to go nowhere. The only good thing about it is the lore, but it is not developed enough.
If you like romance between characters with personalities "different" from the usual romances, then maybe this manga is for you. Otherwise I don't recommend you to read it, you would simply just loose time.
Also, there is no moral to understand from this story despite the behavior and the bad actions of the main character because in the end she gets away with no consequences.
