True and False Daughter

I am a fake daughter among real and fake daughters. However, I suffered all the favoritism, but the real daughter suffered all the injustice. But I was married to a playboy by my parents in the name of love, and was abused after the marriage. Later, the real daughter and I were kidnapped at the same time, and my parents chose to save the real daughter without hesitation. After I died and became an undead, I realized that I was just a tool used by my parents to ward off disasters for the real daughter. When I opened my eyes again, I was reborn.
