Billy was just an ordinary coder in Seoul, defined only by his persistent bad luck. That is, until the day a bullet, meant to end his life, missed him by a miracle.
He soon discovers he is no longer ordinary: he has become the unwitting host of a fragment of the God of Luck's Essence, released during a cosmic war. Suddenly, he can instantly manifest any sincere desire (U.D.), granting him flight, invisibility, wealth, and anything else he wishes.
But this Incredible Luck comes with a terrifying risk. Every night, his uncontrolled dreams (the Astral Fortune Voyages) threaten to materialize his darkest fears or desires, potentially destroying an entire city or even shattering reality.
Guided by Sam, a sentient consciousness he created to stabilize his power, Billy must quickly transition from a passive host to a Master of Will using a vocal command system (Luck).
His goal is not to become a god, but to evolve fast enough to avoid becoming the next target of the God of Misfortune... and to use his power to change people's lives, one sincere smile at a time.
