This spring, Riho earns an unusually early promotion to department manager. She throws herself into the job, but her enthusiasm repeatedly backfires and her coworkers begin keeping their distance. Senior colleague Haneda reaches out and takes the troubled Riho drinking. As the alcohol loosens her up, the normally rigid boss transforms, using a sweet, needy voice to lure him to a hotel. Excited by the secret debauchery of his usually dignified married boss, Haneda gives in, and their drunken encounter slides into an affair with creampies.
