The Missing Piece

Everyone wants his or her life to be a perfect circle, but nothing comes out as planned; the shape of the circle is never perfect. Lin Daofeng has a strange psychological symptom: being silent for five seconds before answering any questions. Because of a sense of guilt due to a childhood event, whenever he is asked a question, he thinks carefully for five seconds without uttering a word. But he doesn't want his life to be delayed by five seconds forever, so every day he goes hitchhiking, hoping to treat his condition through conversation with strangers. In this way, he meets and befriends an intriguing group of characters who became his friends.
