Lu An Ning, a modern woman suffering from a congenital heart condition, dies and finds herself pulled into a black hole, only to awaken in a hospital bed in 1970s China. She has transmigrated into the body of an eighteen-year-old girl with the same name, who suffers from congenital vocal cord dysplasia and a weak constitution. The original owner came from a prestigious military family in Beijing, deeply doted on by her parents, brother, and nephew, yet she had attempted suicide five times due to severe depression. Upon waking, Lu An Ning learns she was poisoned after accidentally mixing cephalexin with rice wine, an act that nearly killed her. She is married to Sui Jingxing, a twenty-one-year-old deputy regiment commander, in a flash marriage arranged after a scandalous incident where she was pushed into a bathroom while he was showering. The two have slept in separate rooms since their wedding, maintaining a distant and respectful relationship.
As Lu An Ning recovers, she discovers that the poisoning was not accidental but a deliberate attempt on her life. The original owner had left behind evidence in a drawer, including a suicide note and a recorded conversation with her attacker, revealing that someone intended to kill her. Lu An Ning, terrified of dying again in this new life, decides to fight for her survival. She communicates with her new husband through a notebook, as she cannot speak fluently. Sui Jingxing, initially unaware of the depth of her illness and the danger she faces, is shocked to learn that his wife has suffered from depression and attempted suicide multiple times. Despite the awkwardness of their situation, he vows to protect her and uncover the truth behind the poisoning attempt.
Lu An Ning’s parents, Lu Sheng and An Nianzhi, arrive from Beijing and are devastated to learn about their daughter’s condition. They express guilt and regret, feeling that their overprotection contributed to her mental state. Lu An Ning promises her parents she will not attempt suicide again, cherishing the healthy body she now possesses. She decides to stay in Yan City rather than return to Beijing, fearing that her changed behavior would reveal her true identity. Instead, she chooses to grow up and become independent, seeking to live a normal life despite her limitations.
Sui Jingxing, determined to help his wife integrate into society, plans to find her a job at a local garment factory. He believes that keeping her busy will distract her from negative thoughts and help her build confidence. Lu An Ning agrees, seeing it as an opportunity to step out of her shell and interact with others. As she begins to navigate her new life, she also notices a mysterious red dot between her eyebrows, a remnant of a ritual performed by her sister in the modern era. She hopes that by replicating the ritual, she might find a way back to her original time, but for now, she is committed to living fully in the present.
The story follows Lu An Ning as she balances her desire for independence with the protective instincts of her family and husband. She faces the challenges of a new era, learning to cook, shop, and socialize while dealing with the lingering effects of her past trauma. Sui Jingxing becomes her ally and protector, gradually breaking down the emotional barriers between them. Together, they work to expose the person behind the poisoning attempt, while Lu An Ning strives to reclaim her life and find happiness in a world that is both unfamiliar and full of potential.
