On the night of the Paris High Jewelry Show, the heroine Su Wan was killed by her best friend Su Qing and her fiancé Gu Yan. Before she died, she discovered that the "Eternal Heart" necklace she had worked so hard to design contained drugs, and Su Qing was using this necklace to complete the last money laundering transaction. What's even more devastating is that her mother's car accident was not an accident, but planned by her stepmother Lin Rou. Su Wan's body was dumped on the bank of the Seine. Before she died, she looked at the Eiffel Tower and swore: "If I could come back again, I want you to pay with your blood!"
