The room opposite the apartment where Yamazaki, who works part-time as a cram school teacher, lives... Could there be such a coincidence? When I was a student eight years ago, my student Nanami, who was a private tutor, lives there. And from the window of her home, the defenseless appearance of Nanami is completely visible. She becomes a married woman and spends her days just secretly watching Nanami, who exudes adult sex appeal. One day when she began to feel such emptiness, she helped Nanami who was being attacked by a snatcher, and the distance between them grew closer again.
