Three years ago, Sophie Carter watched the man she loved walk out of her life without a single explanation. She cried. She waited. Then she finally moved on. Or at least, she thought she did. Now Sophie has a new job, a new life, and a man she is preparing to marry. Then she walks into her new workplace and comes face-to-face with the one person she never expected to see again. Ryan Black. The boy who once promised he would never leave her is now one of the most powerful billionaires in the country. And somehow, he's her new boss. Ryan acts like he has forgotten everything between them. But the way he looks at Sophie tells a different story. Then Sophie discovers the truth about why Ryan left her three years ago. Someone had lied to both of them. And the person responsible is closer to Sophie than she ever imagined. Now Ryan wants a second chance. But Sophie has a question he can't escape: If you loved me so much, why did you leave me in the first place?
