The protagonist becomes interested in a stunningly beautiful new neighbor who just moved in—an office lady. To learn more about her daily routine, he installs a hidden camera in the hallway of their apartment building to observe her behavior patterns. He then gifts her a stuffed animal, secretly embedding a camera inside to spy on her inside her room. Soon, he discovers she engages in sex or masturbation several times a week. He also uncovers another side of her—drinking alcohol turns her into an even more lustful and uninhibited woman. Behind her usual elegant and proper office lady appearance, she harbors a surprisingly bold and erotic side!
