After rebirth, I gave billions of dollars to a fake daughter

My father’s illegitimate daughter, Serena, needed a kidney transplant.

And out of our entire family, only I was a match for her.

Julian Sterling, my fiancé, usually so composed and refined, had a desperate plea etched across his face.

"Astrid, the doctors say you're her only hope. Serena… she's fading fast. Please, save her. I’m begging you."

I chuckled softly. "Alright, I'm willing to donate a kidney to her. But I have conditions."

"Our engagement is off. You marry her."
