Yuichi lives in company housing and has made a daily habit of peering through his window into the apartment across the hall. His boss's wife, Yuria, leaves her curtains wide open, giving him an unobstructed view of her relaxed loungewear and voluptuous body. Yuichi has been drawn to her ever since they were introduced when he helped his drunken boss home. Knowing she is his boss's wife, he tries to resign himself to doing nothing more than watching her from afar, but an unexpected incident suddenly brings the two much closer.
