Cold, impassive Ga Yeong has spent her life under her grandmother's care, whose watchful eye and tough-love approach have helped keep Ga Yeong's psychopathic tendencies in check. When Ga Yeong unexpectedly stumbles upon a magical lamp, she awakens the mysterious spirit Genie from his thousand-year slumber — and yes, he promises the young woman three life-changing wishes. Unleashed into a new millennium, Genie's mischievous magic shakes up Ga Yeong's quiet life, and as he navigates the unfamiliar realities of the modern world, the two find themselves in a surprising whirlwind romance. But just when things couldn't get any less predictable, Ga Yeong learns her wish-granting sidekick is actually Iblis, better known as Satan, who is hell-bent on proving that humans are corruptible. It's a whole new twist on the genie-in-a-lamp story, and when Ga Yeong's intractability and tightly controlled routines meet Genie's trickster energy and clueless charm, it sets the stage for a romance that will be anything but ordinary.
