The film opens in the present day, where Lin Truly (Joe Chen) is an ordinary office worker who leads a stressful life. Her name, “Truly”, literally means “sincere of heart”, reflecting her hard-working nature which often gets her ridiculed by her younger subordinates. Dejected, she listens to a cassette recording of an old Andy Lau song. This brings her back to her high school days, when she was an ordinary high-school girl, who idolized Lau and lived a simple, care-free life. She had a crush on Ouyang Fei-Fan, (Dino Lee), the school’s most popular male student, and had two good girl friends.
