Gu Yanchen, the president of the Gu family, imprisoned his beloved Su Wan in the manor due to a misunderstanding about his father's "falling off a building", destroyed his license, forced her to have an abortion, and built a cage with paranoid hatred. Desperate, Su Wan faked her death, concealed her name with a frozen embryo, and transformed herself into a pediatrician "Wen Xiao" in a small town in the south of the Yangtze River, raising her son An An alone. Three years later, Gu Yanchen, who had returned from his sins, quietly approached as a "neighbor", repairing instruments, picking up children, caring for emergencies, and watering the glimmer of light with forbearance and humility. When the truth of that year emerged with the counterattack of the old enemy Zhao Kun, the pain of miscarriage, the shadow of imprisonment and the tenderness of the moment collided fiercely. He protected his wife with his life and made atonement for his sins. She struggled with the trauma and wavered in the protection. From "possession" to "protection", from "prisoner" to "healer", this seven-year redemption and growth finally illuminates each other's remaining lives in the warm sun.
