Years ago, in an orphanage, twin sister Yuan Shu gave up the chance to be adopted by a wealthy family, allowing her heart-sick older sister, Yuan Bao, to take her place. From that moment, their destinies changed forever... Time passed, and the older sister became the heir to the powerful Sheng family, sparing no effort to search for her sister. Meanwhile, the younger sister was suffering in her marriage, deceived and drained of everything, until she tragically fell from a building in an attempted murder. Upon seeing her sister lying in the hospital bed, the older sister vowed to avenge all the wrongs her sister had endured. Disguising herself as her sister, she returned to their former home, using ruthless methods to slowly repay every injustice her sister had suffered.
