Welcome to the New House of Villains!

What if there was no hero in the world? My name is Han Yuta and I just finished writing half of my first book's prologue when I suddenly got caught up in an accident and died. When I opened my eyes, I was inside that very same book but because of the unfinished content... it was a very difficult situation. 'I haven't even written out the main character! There's no hero yet!' I had just described the world. And it was the perfect world for atrocious villains.
