As a nineteen-year-old college student in Tokyo, he meets a similar-aged Chinese woman during a part-time job at a publisher's warehouse; being born in Japan, she has little ties to her ethnic background. After their final day on the job, they agree to have dinner together and go to the discotheque. After their night of leisure, he mistakenly directs her onto the wrong train. Noticing his mistake, he takes the next train to the last station to reunite with her. After admitting his mistake and the woman confessing her insecurities, he says that he will call her tomorrow before she takes the next train back home. The following morning, he realizes that he threw away the matchbook on which her phone number was written. Despite that gaffe, he tries multiple alternatives to obtaining her number but is unsuccessfully; he never sees her again.
