This work is adapted from Tomato's novel "The Wrong Spring Flower", written by Sophora japonica in the old days. Shen Anran blocked the sword for her fiancé Li Mingxuan, which made it difficult to have a child. Li Mingxuan drank Juezi soup in public and vowed to stay together. Seven years after their marriage, he brought back the pregnant Su Wan at the birthday party. He teamed up with his mother-in-law and the imperial concubine's sister Li Mingya to set up a trap to force her to accept an equal wife. Shen Anran was shocked to realize that blocking the sword was also a deliberate design by Li Mingxuan, and the love he had in the past was all a calculation. She fought back step by step with her medical skills, exposed the conspiracy of everyone in the Hou Mansion, and obtained the imperial decree for peace. In the end, she stayed away from the hypocritical palace, married her husband Shen Zhao, healed her old wounds and gave birth to an heir, reunited with her sisters, and headed for a stable and happy new life.
