Shiraishi is a teacher at a school in Tokyo. He was born into a wealthy family and was brought up strictly from an early age. As expected of his parents and siblings, he graduated from a prestigious university and became a minister. And when I realized that I was working all the time, I was middle-aged and old. It's a desire to surpass and train a beautiful girl... Now that his life is approaching his later years, his desire explodes and he ends up killing "Nana", a student in his class! ＃Yoro P
