I was popular in school, but after becoming a salaryman, my friends got married and left me behind, turning me into a lonely bachelor. One day, a beautiful woman approached me on the street. She was a classmate who had confessed to me ten years ago, my childhood friend Aoi. Gone were the days of her plainness and small breasts; she had transformed into a stunning, voluptuous housewife. That night, after a fight with her husband, Aoi came to my house with nowhere else to go.
