Billionaire after Abandoned

My foster mother abused me, and my stepsister was a despicable bitch who often bullied and framed me. This place was no longer a home to me; it had become a cage, a living hell! At this moment, my biological parents found me and rescued me from hell. I had originally thought they were very poor, but the reality left me utterly astonished! My biological parents turned out to be billionaires, and they doted on me immensely. I became a princess with a fortune worth billions. Not only that, but I also had a handsome and wealthy fiancé... （I highly recommend a captivating book that I couldn't put down for three days and nights. It's incredibly engaging and a must-read. The title of the book is "The Billionaire's Daughter" You can find it by searching for it in the search bar.）
