A young woman, lured into a dating app by her mother's friend, sweetly nurtures a "promoted" young man. (JUQ-591)

Yuna and Mizuki are close friends, both mothers. One day, during a regular tea party, the conversation turns to sex. Young Mizuki seems to have met a young man on an app and is enjoying a vibrant sex life... Yuna rejects the app, saying she wouldn't do anything "illicit," but influenced by Mizuki, she starts using the app for "just once"... Yuna meets Yuzuru on the app, a sincere and submissive man. In her monotonous housewife life, Yuna awakens to a sense of dominance and falls into a pairing trap, becoming completely immersed in it, both physically and mentally.
