This is my first review , I've read the source material long before so I was very happy when the manhwa adaptation came out . "The Novel's Extra" is an exciting story that follows the journey of a struggling writer named Kim Hajin, who finds himself trapped in the world of his own novel. One of the things that make this novel stand out is the unique premise. The idea of a writer being trapped in his own story is intriguing, and the author does an excellent job of exploring the possibilities that this concept presents. The world-building is well-crafted, and the characters are well-developed, with eachone having their own distinct personality and backstory.

Overall, "The Novel's Extra" is an excellent read that is sure to keep readers engaged from start to finish. With a unique premise, well-crafted world-building, and engaging characters, it is a must-read for anyone who loves action-packed adventure stories.
