Dance is the sole means by which Ai Shizukuishi can express herself. While she remains shy and reserved at school, she crossdresses online as a popular dancer known as "Ai." She aspires to surpass Hayate, a free-spirited dancing sensation. As her videos gain popularity, Ai catches Hayate's attention and is recruited by a professional entertainment agency to form an idol unit called "Buddyz"—featuring Hayate himself. However, this is specifically a male duo, and he is unaware of her true gender. If he were to discover the truth, their group would be forced to disband. To further complicate matters, Hayate has a crush on Ai's female persona! As she struggles to keep her gender a secret, Ai strives to break out of her shell through dance and match Hayate. Meanwhile, Buddyz fights against fierce competition to become the best idol unit.
