In her previous life, Shen Qiqi gave her heart to the wrong man and became a vicious cannon-fodder character in the story. The crown prince and her hypocritical half-sister schemed against her together, leaving her family ruined and herself to die with hatred in her heart. Reborn at the age of fifteen, she tears off her gentle disguise and becomes a proud, ruthless daughter of a great clan. She has no interest in competing for the crown prince's favor and no patience for upholding society's good opinion of her. She tears into her white-lotus half-sister, shatters the male and female leads' happy ending, breaks engagements, seizes opportunities, and settles old scores. She acts without restraint, and every move is satisfying. Xie Heng, master of the secret chambers, is icy to the bone, bloodthirsty, cold-hearted, obsessive, and impossible to predict. He kills without mercy and can discard anyone's life at a whim. Even with Shen Qiqi, the woman he cares for, he offers neither tenderness nor indulgence. He remains aloof and ruthless, only intervening in secret when she is cornered, watching her obsessively and coolly standing by as she turns the court upside down.
