Eighteenth-tier actor Lin Wanxing was forced to marry business tycoon Lu Chenyi for his stepsister in order to save the family business. Mr. Lu is rumored to be ruthless and this marriage is destined to be a deal. Until one day after her marriage, Lin Wanxing accidentally discovered a secret that had been hidden for eight years deep in his study - an old photo of her from high school, with young Lu Chenyi's green handwriting on the back: "When will my moon shine?"
It turns out that those characters she thought were chosen by the script were his careful guardians; those she thought were lucky turns were his long-planned approaches. When the door of their hearts is gently knocked open and the truth flows like a river of stars, they realize that all the misunderstandings are just a reunion after a long separation.
Intent: Even if it starts from a cold transaction, love can breed and spread through sincere protection and common growth, and eventually break the wall of the heart, allowing two independent souls to achieve and illuminate each other on an equal footing.
