Never Use Me as a Lucky Charm!

In the Soh family, one daughter is born under a fate that turns her suffering into the family's money. The worse things go for her, the richer the Sohs get. That daughter is Joan Koh, and Amy Lim took her name and her place using a jade pendant as proof. The family believed Amy was the one bringing the luck, and Joan was put to work in the house as a servant. She kept her head down, worked, and paid for her husband Jason Foo's studies. She was pregnant. Amy needed blood to stay alive and Joan was used to supply it, and Joan lost the baby. The grandfather, Richard Soh, eventually saw through Amy. A DNA test settled who was who. At the ceremony handing over the family's hundred billion in assets, Joan came back as Joan Soh and laid out in front of everyone what had been done to her.
