Kazu has a secret love for Shinya's mother, Miki, who is so beautiful and gentle that it can not be compared to her own mother. He always came to Singya's house and looked at Miki with the eyes of his aspiration, and he was always delusional about not being able to do so. One day, when I witnessed Miki who was masturbating at the bathroom, Kazu came up with a plan.
