That JAV

A man has a one-sided liking for a woman he happens to see on the street. He follows her and locates her home. While the woman was away, the man snuck into her room and set up a surveillance camera to monitor her private life. When that was not enough, the man decided to move into the apartment where the woman lived. He continued to monitor the woman at the closest distance in the room next door, which happened to be vacant. The man's desire escalated with each passing day...until finally...!
