Japan's bullet trains are given the go-ahead for deployment in Taiwan at the turn of the century. Haruka who works at a Japanese conglomerate is sent to Taiwan on an assignment. It is not her first time in the country. She had been there before and has fond memories of her male guide for the day. Unfiortunately they lost contact upon her return to Japan and she left that memory alone. Well, six years may have passed, but she is back in Taiwan again.
