The story tells of a hero who banished the darkness, defeating an evil king, and saving the world from destruction - Thomas always loved reading about it in his favorite book, "The Forest King." However, through a twist of fate, he finds himself thrown into the story one year before the story's events. The world he fantasized about was very different, and far more dangerous than what he remembered, while his very presence threatens to destroy everything he cares about. Can he protect the timeline and ensure the hero's destined victory, or will he and the world perish?
