His soul transmigrates into the body of the heir to a duke's estate. He'd planned to coast through life, but his predecessor's reckless behavior left him buried in enormous debt, forcing him to pick up the banner of hard work and charge ahead.

He becomes a true winner in life, sleeping with beauties in his arms and waking with the power of the world in his hands.
