You Favor Your Illegitimate Sister? I’ll Make the Whole Family Pay

I spent my whole life living in my half-sister's shadow. When I was to be granted the title of county princess for my achievements in treating an epidemic, my half-sister wept and said she envied me. My biological brother immediately went before the emperor and accused me of taking credit for her achievements. In the end, my half-sister was granted the title, while I was nearly beaten to death for deceiving the emperor. After I married the heir to the throne, we were deeply in love. My half-sister said she had loved him for years, only to have him stolen from her, then jumped into a lake to kill herself. The heir immediately divorced me and married her. My family thought I had disgraced them and sent me to a nunnery. My half-sister still wouldn't leave me alone and poisoned me. As my life hung by a thread, my own mother shielded her and said, “Were you planning to give your sister that cup of poisoned tea? Thank goodness she didn't fall for it. You're so wicked!” I died in agony right before my mother's eyes. When I opened my eyes again, I was back on the day the emperor was about to grant me the title of county princess.
