Diane makes a deathbed promise to her grandmother to have a baby—only to immediately uncover proof of her husband Miles' affair. Devastated, she ends their seven-year marriage. In a drunken rebound move (courtesy of her bold bestie Maggie), Diane spends a wild night with a gorgeous callboy named Eddie… but her night blindness hides a jaw-dropping truth: Eddie is actually Dominic—her and Miles'college classmate who's been secretly in love with her for years. After studying abroad, he's now returned as a ruthless billionaire… and he'll stop at nothing to win Diane back. By day, he's a powerful tycoon; by night, he voluntarily plays her devoted callboy, determined to make her fall for him.
