It tells the story of Xu Qingzhi, the legitimate daughter of the Grand Tutor's estate, who is reborn back to the day of her coming-of-age ceremony. The tragedy of her previous life—where she was framed and maligned, her biological mother's dowry was usurped, and she was ultimately poisoned to death—remains vivid in her mind. Publicly exposing her stepsister and stepmother's plot, she turns the tables to thoroughly investigate the old dowry accounts, tears up the cold-hearted engagement, unmasks the mastermind who covertly harmed her grandmother, and unearths the hidden truth behind her biological mother's passing. Ultimately, she brings down Madame Liu, reclaims her family's assets, breaks free from the shackles of fate, and takes personal control of her own life.
