Three years ago, Lu Shiyao fell to her death, and the evidence pointed to Su Wan. Lu Shiyan imprisoned and tortured her, forcing her to take her sister’s place. Su Wan endured the humiliation to save her younger brother, who was in the final stages of leukemia, but Lu Shiyan treated her with cold disdain while Lin Weiwei manipulated events and framed her. Her congenital heart condition was ignored, too. Only when Su Wan was critically ill did Lu Shiyan learn the truth. Overcome with guilt, he desperately tried to make amends, only to discover that her love had long since been shattered. When the truth finally came to light, he realized he had hated the wrong person. His tenderness came too late, and all that remained was a regret he could never undo.
