"A dark spell could only make the Mafia Queen fall in love for 49 days. But a fragile Omega... made her fall for a lifetime."
Drowning in massive debt and with her brother's life hanging by a thread, 'Irene,' a gentle Omega florist, is left with no choice but to make a deal with the devil. Forced into a corner, she must use a forbidden 'Spell of Enthrallment' to ensnare the heart of 'Valen,' the ruthless and fiercely cold Mafia Queen, in order to steal the casino's most guarded secret.
The magic only lasts for 49 days. For 49 days, the arrogant lioness willingly surrenders, becoming obsessively, madly in love, laying her entire heart at Irene’s feet.
But when the spell inevitably shatters, the love built on lies violently crumbles. Valen mercilessly throws her out into the freezing rain, her heart consumed by a deep-rooted, venomous hatred. The Mafia Queen has no idea that as she walks away, the Omega carries a part of Valen's 'bloodline' within her womb.
Five years later... Fate plays a cruel joke, bringing them face-to-face once more. Only this time, Irene isn't alone. She's accompanied by a four-year-old girl whose piercing eyes and fierce demeanor are a carbon copy of the Mafia Queen herself!
One returns to claim her revenge and her right as a father (?) while the other must do everything in her power to protect her beloved child.
Yet... beneath the furious glares, the venomous words, and the homicidal jealousy... is it merely the lingering residue of a dark spell? Or is it the true 'heart' of the Mafia Queen... a heart that had never truly let go of her for the past five years?
