On Christmas Eve, Selena is kicked out of her home by her biased father, stepmother, and stepsister Bella. Driven to despair, she rescues a black cat demon and receives three wishes. Spotting the double-curse silver coins embedded in the demon's offer, she turns the rules against him. Her wishes trigger a backfire on Bella—doubling perfect exam scores, massive income, and rapid weight loss into crushing side effects that ruin her reputation and land her in an asylum. Using a daily stream of a hundred million dollars to buy out the family enterprise, Selena bankrupts her greedy father, leaving him homeless, while her fleeing stepmother dies at the hands of the mob. Outsmarting the capital rules to neutralize the soul debt, Selena leaves the cursed coins for other greedy souls, launching a new game of fate.
