The True Heiress Returns

I am a fake heiress who was abandoned after the truth was revealed, but I turned my life around and took control.
To save the family business, I was forced to marry a sickly billionaire I had never met, filled with despair. One night, I got completely drunk and had a one-night stand with a stranger, which led to an unexpected pregnancy. My child was taken away by my family, leaving my heart shattered.
To escape, I chose to study abroad, trying to forget the past. However, upon returning, I wanted to end this loveless marriage, only to be manipulated by my father and unexpectedly entangled with a top billionaire. As we grew closer, I uncovered a shocking truth: he was my legal husband, and his daughter was my lost biological child. Fate's cruel twist forced me to confront my past choices and the pain of lost family, leaving me in a tumult of complex struggles and sorrow.
