The Rebellious Extra in the Novel

One morning, Kim Hajin wakes up trapped inside his own unfinished web novel—but not as the hero. He's a nameless extra, a background character with zero plot relevance. To escape this twisted reality, he must stick close to the main storyline he once wrote. But something's wrong: the world is changing in ways he never imagined, and survival means rewriting his own fate before the story devours him.
