Eh, my interest was pitiqued at first, but all these events are just cheap shock value. When I grew accustomed to the "dark" atmosphere, I found the story to be shallow with barely any character interaction. Also like the other person said, the characters are so far from actual personality that I can't take the doujin's events seriously.
Also slightly bitter that stuff like this and Sugar Sweet Life are tagged yuri but She gets girls everyday is subtext with yuri crush.
