Writing a story in flashback can enhance the story's appeal and tension, but you need to pay attention to the rhythm and structure to avoid confusing or losing the reader's patience. In flashback writing, the story usually has a climax at the beginning and attracts the reader's attention in this way. This way of writing allowed the readers to understand the plot and theme of the story faster and be more easily attracted by the plot. But if the pace is too fast, the reader may lose interest in the story and easily become impatient. In addition, in flashback writing, special attention should be paid to the structure to ensure the logic and cohesiveness of the story. If the structure is chaotic, the reader may not be able to understand the meaning and purpose of the story and lose interest in the story. Therefore, writing a story in flashback can enhance the attraction and tension of the story, but you need to pay attention to the rhythm and structure to avoid confusing or losing the reader's patience.
