When Su Yue, the cherished daughter of the Gu family, was young, her father became addicted to gambling and ran up loan-shark debts. She was handed over to settle his debts and left to wander. Unable to save her daughter, her mother vowed never to depend on anyone again. Fifteen years later, her mother returns as the richest woman in the world, searching for her daughter. Su Yue repeatedly faces hardship: her younger brother humiliates her after spending her life-saving money on extravagant purchases, her seriously ill adoptive mother is threatened, and she is mistreated at her wedding. Mother and daughter cross paths several times, and her mother begins to notice her. But when they finally try to reunite, someone interferes, causing a case of mistaken identity. After her identity is exposed and she faces harassment from the fake heiress, what will the real heiress, Su Yue, do?
