Se after a novel usually refers to the sad ending of the novel, that is, the story ends in tragedy. The reason why it needed to be a Be(Sad Ending) instead of a Se(Sad Ending) was because the ending of a Be was more realistic and closer to life, and it was usually more memorable and shocking. In the process of writing a novel, the author usually shows his emotions and thoughts through different plots and characters, and these emotions and thoughts may lead to the end of the story in a certain way. If the story ended with an Se, it might be too dull or simple, lacking in depth and appeal. Therefore, in order to express the author's thoughts and emotions, and to make the readers better understand the theme and meaning of the novel, the author usually chooses to end it with BE. The ending of the novel may make people feel sad and depressed, but through the author's expression and guidance, the readers can get a deeper level of thinking and enlightenment.
