The nanny who had worked in my house for eighteen years suddenly announced in public that the daughter I raised was her biological child. She also brought another girl over, wanting to seize the daughter, grab shares, and even take away my family. Everyone panicked, only my son and I smiled. Because she didn't know that eighteen years ago, just as she switched the two children, my ten-year-old son personally swapped the younger sister back. Now the higher she jumps, the more miserably she will fall the day the truth is revealed.
