The story begins in 2011. 28-Year-old Shen Zhi suffered a serious injury to his right hand due to a car accident. He was forced to give up his dream of being a surgeon and switch to design work. He has been suffering from PTSD (post-traumatic stress disorder) for a long time, suffering from auditory and visual hallucinations, and his life has come to a standstill. One day, 18-year-old Shen Jichuan—a sunny boy who was studying hard for medical school—suddenly broke into his life. The two people have almost the same appearance, but they are in different time dimensions. Shen Zhi approached Shen Jichuan as a "tutor" and "distant cousin" and started living together. He was familiar with Shen Jichuan's past, which triggered the teenager's speculation about the blood relationship between the two (later denied by Shen Zhi). Shen Zhi's purpose in traveling through time and space is to prevent Shen Jichuan from repeating his own mistakes and avoid the devastating car accident in the future. For this reason, he did not hesitate to disguise himself as a non-mainstream look and personally warned Zhang Yanbin who might threaten Shen Jichuan. ● Two-way healing: Shen Jichuan noticed Shen Zhi's condition (such as having a hallucination in the early morning and knocking over a water glass), and cared for him in a clumsy way; Shen Zhi was gradually melted by the sunshine and love of the young man, and his frozen heart was melted.
● Identity: When two people get along, they confirm that each other is "another self" and develop profound emotions that transcend themselves.
● Ultimate reconciliation: After jointly facing the shadows of the past and future, mutual redemption is achieved. The ending echoes the text: "The wind and snow have stopped, the rushing river has stopped, time has flown back, and love has filled the sky."
