Marrying into a Noble Family to Become the Mistress, Her Delicate Beauty Drives Everyone Crazy

Su Wan, a top-tier celebrity from the modern entertainment industry, transmigrates into the body of a concubine-born daughter named Su Wan in ancient Daliang. The original host had been drugged and assaulted by an unknown man at a monastery three months prior to the story's beginning, resulting in an unintended pregnancy. Upon discovering this, Su Wan’s grandmother, Madam Su, furious at the scandal threatening the family’s reputation and a prestigious marriage alliance with the Lu family, forces Su Wan to the countryside to give birth in secret. Su Wan gives birth to a daughter, Qiong Zhi, and secretly places the child with a relative in the countryside to protect her own standing.

Two years later, Madam Su summons Su Wan back to the capital, Upper Capital, under the guise of familial concern. In reality, Su Wan’s elder sister, Su Lin, who had stolen Su Wan’s original marriage to Lu Guizhou, has been unable to conceive. Madam Su intends for Su Wan to enter the Lu household as a concubine, bear a son for Su Lin, and thereby secure the Lu family’s political and social benefits for the Su clan. Su Wan, aware of her grandmother’s exploitative motives, agrees but only after extracting a substantial dowry and valuable jewelry, using the wealth to fund her own ambitions.

Upon arriving at the Lu mansion, Su Wan finds her sister hostile and suspicious. Su Lin views Su Wan as a rival and a tool, while Su Wan views Lu Guizhou, her sister’s husband, as a handsome but naive and weak man who is wasted on Su Lin. Su Wan’s true objective is not merely to bear a child for her sister, but to dismantle the Lu family from within. She begins by winning over Lu Jiayu, Lu Guizhou’s younger sister, who is insecure about her appearance and struggling to find a suitable husband. Su Wan uses her modern knowledge of skincare and makeup to transform Lu Jiayu’s appearance, gaining her trust and affection.

Through Lu Jiayu, Su Wan gains access to the exclusive Hundred Fruits Banquet, a high-society matchmaking event. There, she observes the social hierarchy and identifies potential allies and targets. She deliberately cultivates an image of innocence and vulnerability, contrasting with her sister’s overt hostility. Meanwhile, Lu Guizhou finds himself increasingly drawn to Su Wan’s beauty and charm, feeling regret over the marriage that was stolen from her. Su Wan manipulates these feelings, creating tension within the Lu household without directly confronting her sister.

Madam Zhou, the matriarch of the Lu family, is aware of Su Wan’s presence and her mother’s schemes. However, Madam Zhou has her own designs; she plans to use Su Wan as a concubine to secure more dowry from the Su family, only to later divorce both sisters for infertility and seize their assets. Su Wan senses this danger and realizes that remaining a mere concubine in the Lu family is a dead end. She decides to pivot her strategy, aiming to elevate herself beyond the role of a secondary wife.

Su Wan begins to network with influential families, leveraging her beauty and intelligence to catch the attention of powerful young men at social gatherings. She maintains a delicate balance, appearing obedient to her grandmother while secretly plotting her own rise. Her relationship with Lu Guizhou becomes complicated; he is torn between his duty to Su Lin and his growing obsession with Su Wan. Su Wan uses this emotional turmoil to weaken Su Lin’s position within the marriage, knowing that a fractured relationship between husband and wife will eventually force Su Lin to rely on Su Wan, giving Su Wan leverage.

The story follows Su Wan’s calculated maneuvers as she navigates the treacherous waters of ancient aristocratic society. She must protect her daughter, outwit her exploitative grandmother, undermine her scheming sister, and avoid the traps set by the Lu matriarch. Her ultimate goal is to secure independent power and status, transforming from a discarded concubine-born daughter into a formidable figure who controls her own destiny, using the men and families around her as stepping stones rather than masters.
