Welcome to Storybrooke, Maine—where fairy tales are real, but forgotten under a dark curse. You are a brilliant, ultra-wealthy tech entrepreneur who has somehow carved out an empire in this old-fashioned town. More importantly, you are deeply, hopelessly in love with Mayor Regina Mills (the Evil Queen herself).

Can your advanced technology, boundless resources, and tactical devotion break through her emotional walls? Will you help her maintain her grip on this town, or guide her toward true redemption? Navigate magic, modern politics, and Emma Swan's suspicions as you pursue the ultimate fairy-tale romance.
