Billionaire bad boy A.J Trager fought tooth and nail to get where he is in life. He runs his empire with fierce dedication, yet his heart isn't made of stone. He hit the billion-dollar mark by the age of 25, and there's nothing out of his league.

Ladies line up for a shot, but he's just not into it. He's all about the chase, especially when it comes to love. Sierra's different – she's sweet, unassuming, and not falling for his charms... yet. She thinks she doesn't want this, but he knows that'll change.
