Because her husband had erectile dysfunction, Hana always had to masturbate alone in the corner of the closet. In the near future, her niece's son will come to stay at her and her husband's house, and he will stay until he finds a job in the city. He has had a crush on Hana since he was young, and meeting her again this time only intensified his feelings.

Despite knowing it was wrong, the feeling of being 'watered' after months of 'drought' made Hana ecstatic. She wanted to enjoy more, to satisfy her own desires. They continued to have sex whenever they had the chance, whether it was a day, a month, or a year passing by, they still maintained this illicit relationship...
