In the winter of the sixth year of Cheng'an, Shen Qingci, the wife of the Crown Prince of Dingguo Palace, died of illness on her bed. Before she died, she discovered that her husband Shen Huaixu, with whom she had respected each other for ten years, had never loved her—he only had his childhood sweetheart and cousin Lin Ruoyun in his heart. And the person she had loved as her sister for ten years was the initiator who caused her to fall into the water, took away her husband, and ruined her life.
Shen Qingci, who was still in despair, opened his eyes and went back to the time when he was sixteen years old - when he fell into the water and was rescued, but everything had not yet begun.
After reviving her life, she is no longer the silly girl who is at the mercy of others. Faced with Shen Huaixu's "life-saving grace", she resorted to tricks and pushed her cousin who was determined to climb high into a pit of fire; faced with her cousin's hypocrisy, she worked step by step to let the white lotus show its true face.
But her transformation attracted an unexpected person - Jin Wang Xiao Yi.
The "rebellious traitor" who rebelled in his previous life and was defeated and burned himself was now staring at her with a half-smile: "Shen Qingci, what secrets are you hiding?"
What she didn't expect even more was that Xiao Yi came to propose marriage on behalf of his nephew, the sick man named Xiao Yan of Kang County who was said to not live to be twenty-five years old.
Facing the coveting of the second prince, the queen's plot, and the prince's wooing, Shen Qingci was frightened every step of the way in the turbulent capital. But the seemingly sickly prince saw through all her disguises with a pair of clean eyes: "Your eyes are just like mine, lonely."
From respecting each other as guests to loving each other, from being dependent on each other in life and death to making a promise, Shen Qingci finally understood: the best love is not to endure and give, but to stand side by side.
