The plot is attractive, but there are unpredictable plot twists or changes in character behavior in the middle of the story, causing the reader's interest to be distracted; 2. The length or number of words of the novel exceeds the reading ability of the reader, causing reading difficulties; 3. The content of the novel is too boring and lacks attractive story plots and characters; 4. The novel's worldview, values, or plot settings are inconsistent with the reader's ideas, causing the reader to feel confused and uncomfortable. These are some of the reasons why readers might give up reading novels. If the readers encountered these problems, they could consider changing the novel or re-reading to find a work that was more suitable for their taste.
