The "cross-dressing romance" centers around Shizukuishi Ai, a shy, plain girl with not-so-great grades and a secret. She posted videos of her dancing in male clothes onto Smile Douga, and she became a viral hit. Ai aims to beat Hayate, the "godly" "prince of dance" on Smile Douga. However, her cross-dressing dances happened to catch the eye of an entertainment agency, so she makes her professional debut — in an idol unit with Hayate. On top of that, the two have to share quarters under the agency's rules.
