Eun Danoh believes she has a perfectly mundane life—until she notices shocking gaps in her memory. One moment, it will be Monday; in another, it is Tuesday, and she has somehow appeared on her school's roof. For some reason, she is the only one who notices anything amiss. She will experience five minutes here, a single moment there, and, the next thing she knows, a week has gone by in a blur.

A mysterious cafeteria worker soon reveals the nature of these strange occurrences—Danoh is a side character in a fictional manhwa being written at this very moment. After meeting an unnamed extra who catches her eye, Danoh resolves to fight against her fate and the rules that constrain her universe.
