Since the first day of high school, Simon and I have competed. Top grades? Simon wins. Better manners? Simon wins. Irresistible stare? Simon definitely wins. So when the bossy billionaire suggests an enemies with benefits arrangement, I dive in headfirst. No feelings. No strings. No falling in love. It's perfect...in theory. Only the Simon who shares my bed isn't cutthroat and arrogant. He's passionate and tender. And pretty soon, I'm losing the one thing that matters: my heart.
