I Was Locked in a Room I Couldn't Leave Unless I Wrote

I am a writer. After frequently abandoning stories halfway through and indulging in absurd antics, I finally managed to offend my readers, who sent me to compete in a contest called "Write or Never Leave." There were five other unlucky souls like me. The readers all thought this was just an ordinary writing competition, but only the contestants knew it was a game where failing to write meant death. Just then, an announcement rang out: "The first round begins. Contestants, please write a novel. Any genre is allowed; choose your own title. Plagiarism is forbidden. The novel must be at least 10,000 words. You have one day." "The clock starts now."
