It's been five years since my husband died in an accident. Her daughter Asuka also got married and her mother Mayumi was spending her happy days. However, her heart is exhausted from spending days with her secret that she can't even tell her daughter... Because of her loneliness, she puts the image of her late husband on her son-in-law, Takanori, and she secretly has a relationship even though she knows it's wrong. Mayumi's body, who remembered her woman's pleasure in her intense fellowship for the moment, unconsciously thought of her Takanori, and she consoled herself.
