Rebirth Heiress of Billionaire Fortune

Wayne Quinn's girlfriend was involved with Ethan Quinn, and the two of them killed him. He woke in the body of Howard Quinn, the eldest son of the Quinn family and Ethan's uncle. He beat Ethan first. Then he spent 200 million on game recharges to outspend him, and set up a trap that lost Ethan enough money that he had to sell his company. He won billions on a billiards wager. He made an idol into a star, and took another six billion off Ethan in the run of deals that followed. The Quinn patriarch arranged a marriage meant to swallow the rival family's group; Howard emptied the Quinn family holdings ahead of it, allied with the heiress, and pushed both Ethan and the patriarch out. He then said publicly that he was the man who had been behind all of it, and took the head of the Quinn family.
