Serena was once the biggest laughingstock of the mafia family—a discarded pawn who was overweight and publicly abandoned at the altar by her fiancé Dante on the day of their "blood-oath marriage." Dante not only swaggered around with his mistress Carmela, but even gifted her a custom-made extra-large bulletproof vest, mocking her, "You can't even squeeze into the family bulletproof vest—marrying you would only waste my bodyguards"—before dumping her on the street where rival factions were exchanging fire, leaving her to die.
In a pool of blood, Serena was saved by an underground black-market doctor, where she met Victor, the dread-inducing tyrant of the underground fight arena. Under Victor's hellish torment and tactical training, Serena shed her weakness and her fat, returning to the mafia world of fame and fortune with scars all over her body and lethal combat skills, transformed into "Siren," the most mysterious information broker on the dark web. Using her stunning beauty and ruthless methods, she lured her enemies deeper step by step, making Dante obsess over her madly, dump his mistress, and lose the support of everyone around him. Just when Dante thought he was about to take control of the entire underworld, he discovered that the woman seated on the highest throne, holding the power of life and death over him, was none other than the fat bride he had once trampled beneath his feet. In the world of the mafia, revenge is a feast that must see blood.
