After the Real Young Master Kicked Me Out, I Rose to the Top

My family's conglomerate was on the brink of bankruptcy, but through sheer hard work, I got its annual profits up to three hundred million. At the school's awards ceremony, my father announced in front of everyone that he'd found his biological son, and that I was the fake young master who'd mooched off him for years. Later, when the real young master fell ill, my father forced me to give him a kidney. “You've cost me so much money. Is it really too much to ask for one kidney in return?” My childhood sweetheart, my girlfriend, sneered, “If you refuse, Uncle will kick you out and leave you with nothing!” I laughed. Then I sold all my shares and signed an agreement severing my parent-child relationship. Before joining the rival company, I even made sure to triple the rent on the conglomerate's headquarters. I made you a three-hundred-million-a-year company, and I can leave you owing hundreds of millions. Sorry, you just laid off the person who kept your company alive.
