After taking a rare day off to attend a pop-up event for a beloved modern fantasy series, an office worker mysteriously transmigrates into that very fictional world. They wake up as a newly hired employee at Daydream Inc., a large corporation in this fantasy realm that appears to be a dream job - complete with generous benefits, excellent pay, and seemingly competent management.

Using their meta-knowledge of the world's lore and characters, the protagonist quickly rises through the corporate ranks. However, they soon discover that their "ideal" workplace harbors dark secrets and supernatural dangers. The company's disclaimer about "injuries or fatalities" during work duties proves to be more than just legal boilerplate.

As the protagonist encounters increasingly horrifying situations disguised as routine corporate activities, they become desperate to find a way back to their original world. The story explores their struggle to survive in a workplace where the mundane corporate environment masks deadly supernatural threats, all while maintaining their professional facade and climbing the corporate ladder in hopes of gaining enough power or knowledge to escape their predicament.
