A super short melancholy BL game with the theme of adolescence and juvenile delinquency. A certain prefecture public high school had 2 consecutive murder cases on September 7, 1997. Autumn is a week after the opening ceremony after the summer vacation. It is a bizarre murder case that occurred in an ordinary public high school. It was a brutal and bizarre murder, and the fact that all the victims were boys and girls in the same class shook the world. Also, the fact that the criminal who was the perpetrator was a boy student in the same class made a lot of noise.
