After a misunderstanding over his father's “fall from a building,” Gu Yancheng, president of the Gu Group, imprisons the woman he loves, Su Wan, in his estate. He destroys her medical license and forces her to have an abortion, building a prison out of obsessive hatred. With her heart dead, Su Wan fakes her death by drowning and disappears under a new identity, taking her frozen embryos with her. In a small Jiangnan town, she becomes a pediatrician named Wen Xiao and raises her son An'an alone. Three years later, Gu Yancheng returns, intent on making amends. Quietly drawing near as her “neighbor,” he repairs equipment, picks up her child, and protects them in emergencies, nurturing a glimmer of hope with humble patience. When Zhao Kun, an old enemy, strikes back, the truth from all those years ago comes to light, and the pain of the abortion and the shadow of her imprisonment collide fiercely with the tenderness of the present. He risks his life to protect his wife and makes amends through his actions. She struggles with her trauma and begins to waver under his care. From “possession” to “protection,” from “prisoner” to “doctor,” this journey of redemption and growth spanning seven years finally illuminates their lives, still smoldering in the aftermath, with warm sunlight.
