Let the Guide Project Begin

After a bout of food poisoning lands her in the ER, the protagonist awakens to find she has possessed the younger sister of an S-Class heroine from the last guide novel she read—only to discover that this body belongs to Lee Go-eun, a tragically frail female Esper fated to die in a violent rampage. In a world where her death would kickstart the original plot, she opens an emergency recruitment to find a compatible Guide, but every candidate shows catastrophic matching rates until an F-Class shut-in named Seo Yi-jae registers a perfect compatibility. Now, with the 'Guide Making' system online and her survival on the line, she must drag this broke, anti-social nerd all the way to S-Class—except his disinterest is rapidly transforming into a terrifying obsession that may derail everything.
