After a drunken night following yet another failed civil service exam, Ryu Gunwoo wakes up in a motel in the body of Park Moondae, a deceased 20-year-old orphan from three years ago. With no trace of his original self, Gunwoo realizes he must now navigate Moondae's life and destiny. Mirroring the fantasy novels he loves, Moondae discovers a status window proclaiming 'Debut or Die,' setting a dire ultimatum: become an idol in a year or face death. To survive, he must excel on Idol Inc., drawing on his past as a paparazzo for insight. As he treads carefully in the treacherous world of idols, one misstep could spell doom for both Moondae's career and existence.
