When the Carter family goes bankrupt, the aloof and refined Ian is brutally dumped by his playboy fiancé, Kevin. But the very next moment, Kevin’s older brother—Arthur, New York’s feared mafia don—appears and offers his entire fortune to enter into a contractual marriage with Ian. What Kevin doesn’t know: the “boring bookworm” he so casually discarded is actually the very same white moonlight he has been searching for all these years. And what he knows even less: his cold-blooded mafia brother has been secretly plotting and waiting for ten whole years just to make Ian his own.
