Three years ago, Chloe, a girl from the bottom, saved a badly injured, amnesiac man named Leo on a rainy night. They fell in love and became husband and wife. But on their third anniversary, Leo hits his head protecting Chloe—and when he wakes up, he hasn't just lost three years of memories. He's regained his true identity: Lorenzo, the most feared Don of the Romano mafia family. Memory-less Lorenzo is cold and brutal, treating the woman who loves him like a scammer trying to cash in. He lets his vicious fiancée Isabella torment Chloe and lock her in a water prison, and—fueled by Isabella's forged DNA report—he nearly kills the child growing in Chloe's womb. In despair, Chloe fakes her death amid a rival family's shootout and goes on the run, pregnant. When Lorenzo finds the charred wedding ring in the rubble, the floodgates of memory shatter and the Don goes mad. Six months later, he finally tracks down his pregnant wife in a seaside town. The once-untouchable mafia boss kneels on broken glass, begging for forgiveness—and when assassins come for her, he shields the door of the delivery room with his own body, hanging between life and death. In the end, facing wave after wave of killers, the once-soft Chloe picks up the Don's golden pistol, becomes the queen of the underworld, defends her man, and walks into a reborn-from-ashes grand wedding.
