Title: Meeting Yourself in a Different Time and Space In the world of novels, we often meet some characters who have a special relationship with us. They may be our old friends, friends, enemies, or even ourselves. The appearance of these people often brings us different experiences and stories. And if I were to write a story about " meeting myself in a different time and space," I might imagine that I'm a time traveler traveling through time and space to meet the people I've hurt and missed, to re-establish contact with them, and to try to change the past. This theme could be applied to many types of novels such as romantic comedies, horror novels, science fiction, and so on. Through this topic, readers can better understand the background and plot of the story, and can better stimulate their imagination to write an unforgettable story.
