Statistics show that many young women working in urban areas live in rental apartments over 20 years old, lacking secure locks or proper safety measures. In this story, a big-breasted office lady moves into such an apartment, only to become the target of eerie, dangerous stares from a middle-aged man living in the neighboring unit. This realistic, serious erotic drama depicts the subtle, persistent harassment young working women faced during the Heisei era, forced to live alone under the watchful eyes of middle-aged male neighbors. Based on actual investigations, the film meticulously recreates real-life circumstances, incorporating both social and psychological contexts.
