The feeling of disappointment after reading a novel may be because you have developed an emotional resonance with the plot and the characters of the novel, but the ending did not develop in the expected direction, making you feel disappointed and confused. Or maybe you were attracted by the novel's worldview, values, etc., but the ending was different from what you expected and made you feel disappointed. The novel was a fictional art form that could arouse the reader's emotional resonance and thinking, and at the same time, it could also allow the reader to obtain different experiences and revelations from it. However, when the readers deeply understand the plot and characters of the novel and realize that the ending is not what they want, they will feel lost and disappointed. However, this was also the charm of novels because they could guide readers to think about and explore topics that they were interested in, and gain new insights and understanding from them.
