This problem involved the plot setting, character creation, and emotional expression of the novel. In the novel, the male protagonist had many wives, which could be a way to show the multi-faced and complicated character of the male protagonist, and at the same time, it could also strengthen the drama and conflict of the story. In some novels, the reason why the male protagonist had multiple wives might be because he had a complicated background and life experience, or because his life experience and personality traits led to him having multiple relationships and needs. In addition, the male protagonist's multiple wives could also reflect the modern society's views and concepts of monogamy and the gender role's rigid image. Of course, in the creation of the novel, the author could also use different methods to shape the character and emotions of the male protagonist to make his relationship with his multiple wives more reasonable and humane. Therefore, readers need to analyze and understand the novel according to the plot and the author's creative intention.
