Luna grew up in a world where tenderness was a rumor and fear was routine. At eighteen, she's all innocence, softness, and wide-eyed wonder - a girl who still believes in pinky promises and happy endings... unaware that her life is about to collide with three men who don't deserve purity yet would burn empires to protect hers. Rafael. Kayro. Leon Morreti. Three brothers. Three kings of the underworld. Three monsters carved from violence, loyalty, and blood. And the moment they find her? It's over. She becomes theirs. Not dated. Not courted. Claimed. Branded. Worshipped. Obsessed over. To the world, they are nightmares dressed in suits - merciless, feared, untouchable. But with Luna? They're something far more dangerous: Gentle. Territorial. Unhinged. Ready to make the whole world kneel just so she never has to cry. But when a phantom from Luna's past - Alexander Mozrov - rises with a sick message and an even sicker obsession of his own, the brothers' darkness stops being dormant. It awakens. It screams. It demands blood. And Luna? She finds herself caught between the tender devotion of three deadly men... and the violent storm of a mafia war waged entirely for her. This is not a love story. This is a possession disguised as destiny. Where kings destroy kingdoms for one girl's smile - and an innocent heart becomes the most dangerous treasure in the underworld.
