It tells the story of Mo Chen running a mysterious cafe in a corner of the city that is only open at midnight. This place allows people to relive the past from the perspective of a bystander, but cannot change it at all. Through the form of a unit drama, the story of guests Lin Yue, Chen Hao, Bai Yun and others letting go of their knots in memories is shown. Mo Chen himself also carries a heavy past - his lover Xia Wan died in a car accident ten years ago to save young Lin Yue, and the truth is blocked due to traumatic memories. Under the guidance of Xia Wan's sister Xia Chu, Mo Chen finally faced the truth about Yu Ye, solved the misunderstanding of Xia Wan's heroic sacrifice, and removed the shackles of self-blame. He realized that the meaning of looking back at the past was to gain the courage to move forward. Eventually, he and his partner Chen Hao expanded the cafe concept into a public welfare project, completing self-healing while redeeming others, making the counterclockwise a warm symbol connecting the past and the future.
