You died on the job—or so you thought. You woke up back at your construction site, but the world has fundamentally changed. Everyone around you—your boss, your coworkers, even the guy selling hotdogs—has developed intense Main Character Syndrome. They treat mundane objects like legendary artifacts and see everyday life as a high-stakes fantasy quest. You are the only person unaffected by this mass delusion, and you have discovered a mysterious, real System interface that gives you actual powers and celestial equipment. Now, you must navigate this bizarre, LARP-driven reality while keeping your head on straight.
