The Tale of Temporary Widower Yoshifuji

Yoshifuji, a merchant, believes himself to be a widower after his wife departs for a week, leading him to embrace lustful thoughts. Unable to resist temptation, he ventures into town, where he meets a beautiful young woman, who is later revealed to be the daughter of a wealthy household. They spend a night together, ultimately resulting in Yoshifuji abandoning his family for 13 years while living with her.
