Lin Tingyu was originally the real daughter of a rich family who was living abroad, but after being found, she was trapped in a cage that was more cold-blooded than the slums. Her gambling father lost all her future, her vicious stepmother coveted her bone marrow, her biased grandmother regarded her as a piece of cake, and the "green tea" fake sister who had taken over her identity for eighteen years was planning to bury her completely with the sweetest smile. When family affection turned into a murderous knife, Lin Tingyu decided to tear this absurd family ethics drama into pieces.
