Zhou Yue is a student at a vocational and technical college in Sichuan. She has never been to a Cantonese-speaking area, but she has been able to speak fluent Hong Kong-style Cantonese since she was a child. Moreover, she has strange dreams almost every night. In her dreams, she seems to be in Hong Kong in the 1950s, and she is always very close to a beautiful girl, hugging, kissing and holding hands, just like an ordinary young couple. Zhou Yue has been very confused until this year's summer vacation, when she met the beautiful girl in her dream again. . . . . .
