Well... I don't really like this kind of stories. I just hate psychological ones like this. Well... it's interesting I guess. I'll be rating this by the first chapter. Since that's the only chapter that I read.
Just as everyone said, "I don't want to go away as a popular girl so I'll turn into a slut so that I could be spoiled."
First of all, that's a stupid mindset to have. Like I'm trying my best not to rate this out of my emotions because I hate these kinds of stories, but the logic and her reasoning is really dumb. The mangaka themselves create great illustrations on what it feels to drown in anxiety and depression. But they manage to badly execute the reasoning behind it.
Secondly, they spoiled the ending in the first chapter. At the first panel of the manga. Well, this causes the reader to be intrigued with the middle chapters and so on. But the ending is dumb as hell. It was shown who died. So that just tosses mystery out of the window like that. It would've been better if it was just shaded so that we can see the ending to hype it up and make a mystery on who really died. But this one just plainly shows literally everything leaving nothing behind for the ending once it reaches that point.
Finally... well... I'm not a fan of the ending of the first chapter. Well, the last 10 pages of the chapter. I just... well... Alright, setting aside my feelings, as I said in the beginning, it's a dumb motive. That's all I can say about that.
With my feelings given in the rating, I'd give this a 0/10.
But as a reviewer, I'd give this a 5/10.
The mangaka themselves portray mental and psychological problems with great illustrations. Anxiety, depression and social pressure all depicted in a single chapter was beautifully done. But the motives behind everything, horribly spoiled ending and well, I won't mention it... But you get the picture.
