After three years of exile my cold-faced cousin begged me to marry into a wealthy family.

Jiang Qingyue was born into the prestigious Jiang family of Yancheng but was secretly swapped at birth with her cousin, Jiang Guiyu, to spare the biological daughter from exile. For over a decade, Qingyue endured brutal hard labor in a northern quarry, suffering frostbite, beatings, and starvation, while Guiyu lived in luxury as the beloved second miss. When a general amnesty granted by the new emperor allowed Qingyue to return, her biological family welcomed her back but immediately pressured her to sacrifice her own future to protect Guiyu, citing political risks and Guiyu’s fragile health. Qingyue was left with no family, returning only to a cold mansion where she was viewed with suspicion and disdain.

Upon her return, Qingyue faced immediate hostility from her brother, Jiang Mingyang, who believed she was a vengeful snake sent to harm the family. She discovered that her former childhood sweetheart, Lu Tingzhi, now a rising official, was engaged to Guiyu, a union Qingyue had once hoped for but was now denied. Despite the emotional betrayal, Qingyue remained focused on her true objectives: treating her eldest sister, Jiang Wanyin, who lay critically ill, and uncovering the mysterious death of her senior sister from the Northern Frontier. Qingyue possessed hidden medical talents learned from an eccentric doctor in the quarry, skills that set her apart from the sheltered noblewomen of the capital.

A pivotal turning point occurred when Qingyue saved the life of He Shi, the wife of the Xuanping Marquis, after a carriage accident. Using rare acupuncture techniques and a precious life-saving pill, Qingyue stabilized He Shi, who had suffered severe internal injuries. This act of kindness brought her into the orbit of Xie Lingyun, the cold and powerful young marquis who had initially transported Qingyue from the quarry. Xie Lingyun, driven by his mother’s wish for him to marry and settle down, began searching for the mysterious female doctor who had saved his mother’s life, unaware that she was the same woman he had treated with such indifference.

Back at the Jiang mansion, tensions escalated when Jiang Mingyang accused Qingyue of poisoning his sister Wanyin after she collapsed while drinking medicine prescribed by Qingyue. The family’s servant, Mama Wang, locked Qingyue in a filthy latrine as punishment, subjecting her to further humiliation. However, the family physician later confirmed that Wanyin’s collapse was actually a healing crisis, indicating that Qingyue’s prescription was correct and beneficial. The physician also revealed that Guiyu’s chronic cough was likely feigned or exaggerated, a secret he hinted Qingyue should be wary of.

Jiang Shouye, Qingyue’s father, reprimanded Mingyang for his cruelty but showed little genuine concern for Qingyue’s well-being, focusing instead on the family’s reputation. Qingyue realized that her return was not an act of love but a strategic move to use her as a substitute bride for Wanyin, who was to marry into royalty. Despite the betrayal and abuse, Qingyue remained composed, using her medical skills to gain a foothold in the household. Meanwhile, Xie Lingyun’s search for his savior intensified, creating a potential alliance that could shift the power dynamics in Qingyue’s favor as she navigates the treacherous waters of the capital’s aristocracy.
