If you want to write a light-hearted and interesting novel, you can consider the following theme: An ordinary office worker accidentally discovers that he can travel through various stories, and in each story, there is a small task to be completed. He began a unique journey, shuttling through different story worlds, flying like a butterfly. Sometimes he would be the main character, and sometimes he would be a supporting character. Different missions and different worlds made his life rich and colorful. Fantasy, romance, suspense, sci-fi…Every world had different stories waiting for him to discover and travel through time.
