"After Divorce, Bai Yueguang is Myself" tells the story of Shen Zhiyi, who has been Gu Yanci's "substitute wife" for three years and has been living in the shadow of "Bai Yueguang" in his heart. She imitated the mysterious woman's dressing style and wore her favorite accessories, but she received indifference and neglect from her husband. When the real "White Moonlight" Lin Wan returned to China, Shen Zhiyi was disheartened and resolutely filed for divorce.
However, fate plays tricks on people. Shen Zhiyi discovered in Gu Yanci's study that the girl in the photo of his first love that he had collected for fifteen years was actually the girl who saved him when he was a child. It turned out that Gu Yanci lost his memory at a young age and could only remember the fragments of his savior. He mistakenly identified the returning Lin Wan as that person, and chose a clumsy test because he did not dare to confirm Shen Zhiyi's identity. As a result, the two tortured each other for three years.
After the truth came out, Gu Yanci regretted it and started a long road to pursue his wife. He put aside his pride, used sincerity and actions to melt the ice in Shen Zhiyi's heart little by little, exposed Lin Wan's conspiracy, and fully supported Shen Zhiyi in pursuing her dream of jewelry design. In the end, Shen Zhiyi won the international competition, proved his worth, and accepted Gu Yanci again. After resolving their misunderstanding, the two remarried and gained true happiness and fulfillment.
