Shimazaki Osamu, a loner and gloomy high school writer, was eating alone at a family restaurant. On his way out, he encountered a beautiful girl who seemed to be troubled. When a worried Shimazaki called out to her, she seemed to have forgotten her wallet and looked as if she was about to burst into tears on the spot. Intending to treat her, he paid for her share as well, but after that, the beautiful girl took him to her house, saying that she will have the money then. At first, they are just curious about each other, but gradually they become attracted to each other──slowly but surely, their relationship deepens. The two, who are clumsy when it comes to love, gradually grow closer to each other while making those around them jealous.
