In her past life, Shen Zhiyao risked her life to save her eldest sister, only to be framed by her and plunged into endless misery. Opening her eyes once more, she returned to the Marquis's banquet, right as the tragedy was about to replay itself. Her eldest sister feigned weakness, hoping she would step forward once again to block disaster for her. Living a new life, Shen Zhiyao completely stripped away her past foolish kindness, choosing to preserve herself. Step by step and with composure, she exposed the careful plots of the inner courtyard and rooted out the evildoers behind the scenes. Neither attached to the glory of the Marquis's estate nor hoping for family pity, she relied on reason to gather evidence, making the wicked receive their due punishment, and struggled fiercely to break free of the crimson mansion's shackles, earning herself a secure and peaceful remaining life.
