A student named Haruo was struggling with his lack of popularity during his school days. To change his life, he honed his skills on a dating app called Matching App. Every day, he enjoyed one-night stands with horny women, which helped him become skilled at sex. He particularly excelled at seducing unhappy housewives who were thrilled to cheat on their husbands. One day, as usual, he matched with another woman and prepared to indulge in passionate lovemaking when something unexpected happened... It turned out that the mysterious beauty was none other than his former classmate, Tomomi! She had been part of the upper echelon of their school's social hierarchy while Haruo languished as a nerdy outcast. Despite recognizing each other, they both hesitated before giving in to their desires.
