I'll get right to the point for this.

The manga has interesting ideas, I really like the main characters, but they run with an idea that they do not go beyond the basics of.

No spoilers, since its just a very quick thing about her invisibility. This is what I was talking about with the idea they had. They got the idea, and they only rolled with what was comfortable with it, and in the end the conclusion I got from it all wasn't satisfying in the least. I would've loved to see it used more creatively.

Its basically a stalker who can stalk easier in public due to her power and they throw them in a punch of basic situations that only once or twice take full advantage of what could happen. They hardly interact with each other while she is invisible (as in accidental physical contact, they minimize that and you can really see how basic it is as it goes on as they keep doing the same thing), and it just sort of feels like the mangaka just ends up rushing the ending.
