Undergraduate Chloe, a girl from a humble background, takes a part-time job at a lavish banquet to earn tuition fees, but accidentally stumbles into the suite of Dante, a mafia don who has been slipped an aphrodisiac, and is forced to go through a wild night. After sobering up, Dante mistakes her for a ruthless gold-digger and dismisses her with a black onyx cross necklace and a stack of dollars. This life-saving sum is immediately snatched away by Chloe's greedy relatives, leaving her to swallow the bitter humiliation alone.
Eight months later, the pregnant Chloe is driven to the end of her rope. Her gambling-addicted uncle not only steals the prenatal check-up fees she has scrimped and saved, but also, when she is weak and on the verge of collapse, tries to drag her forcibly to a back-alley clinic to abort her unborn child, selling her to an old drug dealer in exchange for a bride price. During the life-and-death struggle, the token necklace falls and shatters. Dante, who learns the truth, is wracked with remorse; he descends on the hospital ward like a grim reaper at the head of a large contingent of mafia bodyguards. At Chloe's most desperate moment, he crushes all threats with unchallenged authority and takes the Cinderella carrying the mafia heir back to his heavily fortified estate.
After their reunion, the cold-blooded, violent don is completely smitten, transforming into an unprincipled "wife protector". Faced with school bullying from snobby classmates, a deadly plot from her birth family, and vicious framing by a fake "white moonlight", Dante uses his overwhelming power to send everyone who bullies her to hell one by one. He not only hires a hundred craftsmen to work through the night to restore Chloe's ruined graduation wedding dress with crushed diamonds, but also kneels on one knee at a banquet broadcast live across the city. This mafia love fairy tale interwoven with money, power and extreme doting finally comes to a perfect end with a century wedding that stuns the whole city.
