Housewife Misa (42) has been remarried for five years, with no children. After her first marriage, she became a full-time homemaker as her husband wished, but couldn't give up her passion for the hotel industry and returned to work two years later. Unable to understand her dedication to her job, her husband eventually led to their divorce. For the next ten years, she threw herself entirely into her career, eventually finding new happiness with a hotel worker from the same workplace. Their relationship, built on mutual understanding and respect for each other's work, is described by Misa as ideal for a married woman. Yet after five years, she feels something is still missing, prompting her to embark on a journey. A single night with a man she's never met before deeply shakes her heart, driving her into intense, overwhelming ecstasy.
