My name is Lin Xiaoyu. I'm a failed author who's spent 20 years setting up plot hooks, and my greatest achievement is setting a Guinness World Record for “365 consecutive days without an update.” Then one day, my comeuppance arrived: I stayed up late working on a draft, slumped face-first onto my keyboard, and opened my eyes inside the dark fantasy novel I'd abandoned three years ago, The Demon King's Consort!
The good news is that, as the original author, I have “authorial omniscience” and the “power to rewrite the plot.”
The bad news is that I've become a cannon-fodder NPC who gets crushed into a meat patty by the Demon King in Chapter Three.
Even worse, thanks to my terrible ending, the world is falling apart: magic is failing, the plot is stuck, NPCs are awakening en masse, and the ultimate boss has even discovered the existence of the “fourth wall.”
