Описание: Short Drama Synopsis: After Marriage Exchange, I Helped My Husband Achieve Great Heights
Shen Qingci, a wise and resilient illegitimate daughter from a scholarly family, was forced by her clan to take her elder sister’s place in a marriage exchange, marrying Gu Yanzhi—a talented but down-and-out scholar whose family fell into ruin due to an unjust case.
On their wedding night, Shen Qingci vowed to help Gu Yanzhi clear his father’s name and realize his ambition, while Gu Yanzhi, who was inferior and helpless at first, was deeply moved. Facing the persecution of Gu Yanzhi’s greedy stepmother and the jealousy of her own elder sister, Shen Qingci remained calm and resourceful: she used her accounting skills to earn money for Gu Yanzhi’s studies, sought recommendations for him to take the imperial examination, and repeatedly fought back against the villains to protect their family.
With Shen Qingci’s wholehearted support, Gu Yanzhi regained confidence, studied diligently, and finally passed the imperial examination with flying colors. He then investigated his father’s unjust case step by step, with Shen Qingci helping him find clues and gather evidence. In the process, Shen Qingci also revealed her hidden business talent, starting an accessory business and becoming a well-known female merchant in the capital.
Eventually, Gu Yanzhi cleared his family’s grievances, was promoted to a high official by the emperor, and became a pillar of the court. Shen Qingci, who was later exposed as a princess’s daughter, was granted the title of noble lady. The two supported each other through thick and thin, turning their forced marriage into a lifelong companionship, and achieving both career success and a happy marriage.
