Author really knows how to deliver pain and horror as much as they know how to deliver love and tenderness. I read the first chapter years ago and was horrified, I couldn't stop thinking about it and felt horrified again, from time to time I became brave and read again just to be horrified again. Truly a work of art.
It's funny to see fans that came to her works thanks to Doukyuusei... calm down, y'all.
