Yet despite his jaw-droppingly good looks, Cally, who grew up in an imperfect family, shows no interest in love or marriage, and she plans to cut ties with him as soon as they fulfill the conditions of the auction. Blake, driven by curiosity about Cally's inner self, proposes a further condition. Cornered by Blake's approach, Cally accepts his bet, even though the stakes are high... If she loses, she'll become his slave for a day and have to do whatever he wants!
