The second live-action adaptation of Sasamori Tomoe's hugely popular comic series, which has sold more than 300,000 copies. A shut-in whose only talent is gaming decides to test his skills in a tournament and begins searching for teammates. The three candidates he meets through social media are all beautiful, busty, curvy older women. As the group grows closer, he starts sexual relationships with Mayumu and Ayaka one after another. Their secret affairs continue alongside the team's regular gatherings, while married Nanako supposedly remains unaware—until she does not.
