Nanako Ozaki, 53, looks good with her clean and elegant short haircut. She is a full-time housewife who has been married for 25 years. It has been a year since her only son left home to find a job... Nanako is starting to feel bored with her life with her husband, and their sex life has recently become monotonous. "Every day is the same...there is nothing exciting. I think of myself as 'still' 53, but is that wrong?" Since deciding to appear in the film, her expectations have risen to the point of bursting at the thought of having sex with a professional actor, and her carnal desire, which is too strong to be called Kokoro, flares up.
