Nakagawa is an unsuccessful freelance writer who lives in a certain apartment. I was writing a manuscript on the theme of "Married Woman's Libido and Its Reality". When I am taking a break on the veranda for a change of pace, I notice a moving shadow in the Japanese-style room next door. The married woman living in the next room was in the middle of changing clothes. Nakagawa is glued to the spectacle of unreservedly exposing her naked body in broad daylight. Lewd fantasies like eromanga come to mind one after another.
