Mu Xue was about to marry Si Yu in her previous life, but she didn't know that Si Yu had a lover. Si Yu and Xu Man planned to break the Mu family's capital chain, defrauded the Mu family of shares, forced Mu Xue's parents to death, and finally arranged a car accident to silence them.
Muxue woke up again and found that she was Si Xiaoxiao, the illegitimate daughter of the Si family who had just been taken back. She was shocked to find that she actually lived in her enemy's house and even called Si Yu "brother".
Everyone thought Si Xiaoxiao was weak and easy to bully, but she was the only one who knew that the real Muxue had already died once.
She began to pretend to be good, show weakness, and collect evidence, while sabotaging Si Yu and Xu Man's plan while searching for the truth about the destruction of the Mu family. She wanted Si Yu to watch her lose everything she wanted most.
Mu Xue was defrauded and killed by her fiancé Si Yu. After her death, she was reborn as Si Xiaoxiao, the illegitimate daughter of the Si family. Everyone thought she was just a cowardly fake daughter, but little did they know that the real avenger had returned to her enemy.
