Nene Yoshitaka originally wanted to be an idol, but her agency paired her with Ai as a comedic duo. She and Ai had always been rivals, and she never expected to be paired with her. To make matters worse, Nene was responsible for the comedy, while Ai was responsible for the witty remarks. This sense of defeat led her to decide to steal Ai's boyfriend, Iida. Iida is a veteran entertainer who isn't famous and has an extremely masochistic S-type personality. However, after sleeping with him, Nene, during performances, whenever Ai hits her, she retaliates by hitting Iida, turning him into an M-type personality.
