Rebirth, the Real Daughter Took the Fake Daughter's Script

Since I was little, I have been living in fear. Try to be a good baby in the eyes of your parents, be well-behaved and sensible, and work hard to make progress. Try to flatter your brothers and sisters and build a good relationship with them! Keep a distance from your fiancé, and don't have any emotions with him. Because I am not the real eldest daughter of the Chi family, I hope that when the real daughter comes back, she will leave me a way out for the sake of my understanding.
