Kiyoha Yumise is a huge fan of the boy band Polaris, specifically of the member Aoto. Kiyoha frequently wonders what Aoto is up to since leaving the band years ago, and is shocked when her company's new hire turns out to be him!! Kiyoha is left in charge of training Aoto, but is flabbergasted by the cold shoulder he seems to give only her. Despite being convinced that Aoto hates her, he somehow winds up at her house to spend the night. Aoto is determined to make her feel good as thanks for her hospitality, and one thing leads to another...!
