A hit work by popular creator Shiwasu no Okina finally receives a live-action adaptation. Tatsuji is a hopelessly unpopular adult who has confessed his feelings one hundred times and been rejected every time. Seeing him crushed, five female friends—all of whom already have boyfriends—throw him a karaoke party. Hoping for masturbation material to ease his heartbreak, he asks them to share stories about sex with their partners. Instead, the conversation erupts into a flood of affectionate, girlfriend-style sex as all five show him exactly how they make love to their boyfriends.
