The Return of the Legitimate Daughter: The True Heiress Reborn

Su Leyun lived a tragic life as the legitimate daughter of the Su Marquis Manor, though she was unaware of her true status for fourteen years. Swapped at birth with an adopted daughter named Su Wan'er, she endured a life of abuse and servitude in a rural village. Upon being discovered and brought to the capital, she was rejected by her biased grandmother and indifferent father, while Su Wan'er was cherished. Desperate for acceptance, Su Leyun married Li Rui, a scholar she loved, only to discover that the marriage was a scheme orchestrated by Su Wan'er to remove her from the household. Betrayed and isolated, Su Leyun watched her mother die of illness and her grandfather and brother perish in a framed military disaster. Cast out by her husband's family, she sought refuge in Longyue Nunnery, where Su Wan'er eventually tracked her down. In a brutal confrontation, Su Wan'er murdered Su Leyun's loyal maids and stabbed her to death, revealing her role in the deaths of Su Leyun's mother and family.

Reborn in an inn in Jingzhou City, Su Leyun returned to the moment she first arrived in the capital, armed with the memories of her past life. She resolved to change her fate, protect her remaining family, and exact revenge on those who destroyed her. Her first test came when she encountered Prince Jin, a fugitive prince being hunted by government officers. Recognizing him as a key figure from her previous life who died young, she bargained with him, securing his jade pendant and a promise of future aid in exchange for her silence and assistance in evading capture. This encounter marked the beginning of her entanglement with the dangerous political struggles of the royal court.

Upon arriving at the Su Manor, Su Leyun faced the cold hostility of her grandmother and father, who continued to favor Su Wan'er. She deftly navigated the social minefield, displaying impeccable etiquette and intelligence that silenced rumors of her rustic upbringing. During a family school session, she humiliated Li Rui, who had come to visit Su Wan'er, by delivering a profound commentary on governance that exposed his arrogance and lack of substance. Her performance earned the admiration of her teacher and peers, while simultaneously distancing herself from the man who had betrayed her in her past life.

Her brother, Su Ye, a military strategist and Prince Jin's study companion, became her staunchest ally. Together, they worked to establish her identity within the family. Su Leyun revealed a unique birthmark to her mother, Sun Jiarou, which confirmed her lineage and began to shift the family dynamics. However, obstacles remained, as the midwife who could provide definitive proof had disappeared, suggesting a deliberate conspiracy to keep her status in question. Prince Jin, intrigued by her resilience and intelligence, continued to watch over her, creating a complex web of political and personal alliances.

As the New Year approached, Su Leyun prepared to publicly assert her place in the Su family. She refused to be manipulated by Su Wan'er's schemes, such as the attempt to embarrass her with a gift of a brush meant to highlight her illiteracy. Instead, she turned the tables, exposing Su Wan'er's malice and Li Rui's prejudice. The story follows her strategic maneuvering through the treacherous waters of noble society, as she seeks to clear her family's name, uncover the truth behind her grandfather's death, and dismantle the power of those who wronged her, all while navigating the dangerous succession struggle involving Prince Jin.
