A 7-year-old rental apartment located a 7-minute walk from the station, close to the city center yet offering a well-maintained living environment with furnished appliances. A man working for the company managing this popular property harbors twisted desires. The woman, estimated to be around 30 years old with the appearance of an office lady, returns home, changes into a yukata, finishes dressing while talking on the phone with a friend, then leaves the apartment. While she's out, the man sneaks into the vacant room and rummages through her discarded suit and underwear. Several hours later, the OL returns, unaware that the man is hiding beneath her bed, and begins to relax. She drinks tainted water, loses consciousness, and is quietly violated as her yukata is stripped away and her thong is torn off.
