Li Qingzhou and Wan Muqing met when they were teenagers, but three years later Wan Muqing was poisoned and tortured by his inner demons. His father died trying to help him suppress his inner demons. Later, Wan Muqing's mother Tan Ruxun decided to take Wan Muqing and Wan Muqing's two sisters to leave Jingsu and study medicine with Tan Ruxun's father in southern Hunan (both Jingsu and Xiangnan are fictitious place names). Later, Li Qingzhou and Wan Muqing separated. Five years later, the two met again but did not recognize each other. They stayed together for a few days after the meeting. Later, an accidental incident made the two recognize each other. However, their emotions were close to collapse. They separated again a few months later. A year later, the two met again. Li Qingzhou walked with Wan Muqing in the rivers and lakes, and helped him suppress his poison and eliminate his inner demons.
