Takashi is single and lives in a small apartment. Because he doesn't have a stable job, even finding food to eat becomes a difficult problem. One day, while walking down the street, a girl calls out his name. It feels like he has met her somewhere before, and when she says she is his childhood friend, named Rio, Takashi suddenly remembers. Ten years ago, when he was still a student, Takashi was quite popular with girls. There was a shy girl who styled her hair in frizzy curls to confess her feelings to him. Of course, Takashi did not agree, Rio at that time looking both awkward and funny. Yet, after ten years, she has transformed into a very beautiful woman! The two greet each other and exchange contact information. As soon as Rio returns home, her husband scolds her, suspecting that she is cheating, and then she goes out to drink. Feeling dejected, Rio immediately thinks of Takashi; she has always had special feelings for him...
