Dance has always served as Ai Shizukuishi's method of self-expression: an emotional outlet that allows her to be her authentic self. Using the pseudonym "Ai," she posts videos of her performances—where she cross-dresses—on the Smile Douga platform. Even as she gains considerable popularity, Ai stays dedicated to her ambition of eventually surpassing her idol, the "dance prince" Hayate. Hayate soon notices Ai's dance talent, though he remains ignorant of her gender. Following their participation in the same audition, the two are placed in an idol group named Buddyz and enter an all-male dance competition. Adding to the complexity, as the rivalry between Ai and Hayate intensifies, so do Hayate's romantic feelings for Ai in her female persona.
