Shizuku Ishiai, a 2nd year middle school student, loves dancing, but is bad at expressing herself, so she crossdresses and posts videos of her dances on the popular website "Smile Douga," under the alias "Ai."

But, after a few unexpected events, and her attempts to best him, she's somehow thrown into an idol unit with him; furthermore, a MALE one?!
