The billionaire CEO became my kept boy

Joshua's mom came from a top-tier elite family, but she was deceived into a sham marriage by Joshua's dad James. In the end, she died sick and broken, thanks to James's schemes with his mistress. Joshua left home in college, built his own company from scratch, and was later found by my mom's powerful relatives. Taking his mom's family name, Joshua became Jake Dawson. Then he returned to Sea City, masterminding a ruthless business war to bankrupt his deadbeat father. Under the name Jake Dawson, he secretly reclaimed his mom's company—piece by piece.
