A 7-year-old rental apartment building located a 7-minute walk from the station, close to downtown with convenient living amenities, fully furnished with appliances. A male employee working for the management company begins acting on his impure desires. Obtaining the master key, which was supposed to be securely stored, he infiltrates the apartments where female tenants live. One resident, a 21-year-old job-seeking woman who practices piano after returning home, receives a call from a friend. They exchange job-hunting information when suddenly she's told she must wear a suit for recruitment purposes. After the call, she puts on the outfit. Unaware of the danger, she drinks a beverage laced with ●, loses consciousness, and falls victim to the intruder. Her body is violated as her sensitive genitals secrete copious amounts of arousal fluid, and she is ultimately raped by the man's penis.
