Built seven years ago, a rental apartment conveniently located just seven minutes on foot from the station, close to downtown with furniture and appliances included. The manager of this popular property possesses a closely guarded master key. Driven by twisted desires, a man obtains it to sneak into the rooms of female tenants. The target: a woman estimated to be 22 years old, with the appearance of a student. After returning home, she changes into a new swimsuit she purchased, checks her reflection in the mirror, and carefully trims pubic hair with scissors and tweezers. Once finished, she drinks water from the refrigerator. However, the water has been laced with a substance, causing her to lose consciousness. The man sneaks into her room and begins his quiet mischief, violating her immobilized body.
