Lin Yaoguo (Jacky Cheung), a 40-year-old Chinese teacher at a middle school in Hong Kong, is a "nice guy" who has disappeared. He was a famous talent in school when he was studying, but now he only feels an unspeakable loss when facing his former classmates who have become successful and play golf in their spare time. However, in the eyes of his "bad student" Wu Cailan (Karena Lam), he is a mature and charming man with connotation. Wu Cailan has some of the shadow of Lin Yaoguo's wife Wen Jing (Anita Mui) in the past. Her bold love reminds Lin Yaoguo of a past that is deeply buried in his heart, touching the pain in his heart. The romantic and poetic dream of the past can only be put at the bottom of the box, and the responsibility that he chose to take on, which did not belong to him, has been carried for twenty years. In addition to other unexpected things, he was at a loss for a while, but he had to make a choice.
