The story is about two female cats Shito and Zero and their chatterings. Their owner is a junior high school boy, who stays indoors and plays video games. One day the cats find the boy fallen in love with his classmate. Shito sympathizes with him because she is also in one-sided love with a male cat. In the movie, all the cats were personified and played by human actors.
