Four office ladies work at Toaru Computer Parts Maker, an ordinary office setting. Their daily routines are disrupted when they encounter four distinct men: the Wolf, the Irresponsible Man, the Devil, and the Prince. Each woman becomes entangled in a romantic and intriguing relationship with one of these men, whose personalities range from predatory and careless to dark and princely. The manga is composed of three interconnected short stories: The Reference Room's Daughter, which follows a quiet employee and her secret encounters; The Irresponsible Game, centering on a reckless affair; and The Devil's Invitation, where a dangerous seduction unfolds. Together these arcs explore the excitement, tension, and emotional risks of office romance as each woman navigates desire and power dynamics within the workplace.
