Nami is 24 years old, married for two years, and has no children. Her husband is a professional keirin cyclist, and during racing season, he faces strict restrictions on outside contact due to the regulations surrounding public gambling—this includes his wife. During the season, they're only allowed to speak on the phone once a week. Because of this, Nami has always felt anxious and depressed every time the season approaches. However, her feelings began to shift last spring when she met someone by chance. She was invited to a party by the owner of a surfboard shop in Shonan that she frequently visits, and there she met an older man. At first, she thought he was just a wealthy company president who owned a yacht and was somewhat famous in the Hayama area, but she soon discovered an unexpected side of him—one that deeply stirred her emotions.
