I Will Kill The Author Novel

I was just an ordinary guy, living a dull and unremarkable life as an editor.But when a maniac author killed me for rejecting his novel in a writing competition, I reopened my eyes in a modern fantasy world.“Hmm? Wait, this world….”But fate, being a prude little bitch, played a twisted joke on me.I reincarnated into the very same novel that I rejected for the competition award, written by the very same author who killed me for it.Not only that, but I transmigrated into the body of a disowned noble named Lucas Morningstar.Lucas was a minor antagonist in a novel who served as a stepping stone for the protagonist and their allies.Arghh….Of all the people, I just had to be reborn as someone who was despised by the main characters the most at this point in the story?B-But hey, with my knowledge of the future and understanding of the main characters, I can at least live an easy life!Right...?“Yeah, I can work with this!”Or so I thought until I remembered the ending arcs of the book.This world is destined for doom!And not so long after, I started to realize that the novel and the world I transmigrated into might not be as similar as I had originally thought….
