Mu Xiaoning's life was shattered when her father's mistress brought her daughter, Mu Rourou, into the family. Her engagement to the powerful Lu family was stolen away, and she was cast off to grow up in a remote mountain village, where she met her mysterious mentor, Xu Rugui—who turned out not to be a legendary hemit physician.
Years later, Lu Shenyuan—the very fiancé once stolen from her—suffers a crippling car accident and is told he has less than a year to live. To secure the Lu family's immense dowry, the Mus bring Mu Xiaoning back and force her to marry in her sister's place. What begins as a desperate arrangement soon sparks a storm of vengeance, hidden power, and a marriage no one expected.
