After being framed by the fake daughter, Shen Xi, the real daughter, was personally sent to a mental hospital by her brothers. She "recovered" and returned half a year later, becoming extremely obedient, but quietly dragged everyone into a carefully designed abyss. She smiled and cut open the mask of the hypocrite, and made every step of the way to let the abuser reap the consequences. When the brothers finally discovered the truth, the sister who once longed for family affection had long been tempered into the most exquisite sharp blade - she no longer needed to be loved, and just wanted to watch everyone fall into the hell she had struggled with.
