This manga is unpredictable.

I read this when I was like 9 or 10 and it was amazing, it's a physiological manga.

It has many twists that make you flip, although this is a shoujo, I can see males enjoying this manga too (if they're not picky). This has VERY, VERY, VERY light romance.

It focuses on the plot rather than useless conversations or actions that don't contribute to the story. The art is beautiful and simplistic, the covers are wow.

In terms of character development, it progresses steadily. I gave an 8 as an enjoyment because I would have enjoyed some Tsubanabe, but I guess that's just a preference.

I don't really see anything bad about this manga, the characters have their own backstory of why they have turned out that way. This makes the antagonist interesting and enjoyable.
