Knox’s life is a dead-end, burdened by his abusive, gambling-addict father’s staggering debts. With a twenty-eight million won deficit and a cynical outlook, he’s desperate for an escape from his bleak reality. A mysterious, ancient parchment offers a cryptic invitation, pulling him into a world far beyond his mundane existence. This invitation leads him to the Obelisk Hotel, a sprawling, supernatural establishment nestled deep within Hell. Here, the clinking of chips on the “Pleasure Floor” casino mingles with the whispers of non-human staff like Rabisisa. Knox, a mere mortal, is thrust into a realm where human rules don’t apply, and even a simple drink can be perilous. He encounters figures both alluring and terrifying, from the playful Noara to a silent, goat-masked entity. Having joined the Underworld Hotel, Knox must navigate its opulent yet chilling corridors. Is he a guest, an employee, or merely a pawn in a grander, infernal game? With his past debts looming, he must learn to survive in a world where every turn could lead to fortune or damnation, all while trying to understand the true nature of the hotel and its powerful residents.
