The moonlight of Erhai Lake witnessed an encounter that started with a mistake. Lin Wei, a Master of Fine Arts from Beijing University, resolutely ended her three-year marriage after discovering that her husband Tang Qi had cheated on her, and fled to Yunnan alone to recover. At the "Erhai Moon" Inn on the shore of Erhai Lake, she met Xia Yu, the president of the business empire who also came here to bid farewell to the past. Two people with wounds met love beautifully and finally came together. Later, due to conflicts, Lin Wei resolutely quit her job and went to France. Later she settled in Yunnan, gave birth to her son Muchen, opened a personal studio and became an independent artist. For three years, Xia Yu searched frantically in regret and completely cleared all obstacles. Three years later, they met again in Lijiang and had a son.
