There were a few points to note when writing Doujin novels: 1. Decide on the theme and worldview: The theme and worldview of a doujin novel should be different from the original, but the emotions and plot should be similar. The theme and worldview needed to be carefully considered before the creation to provide a solid foundation for the story. 2. Deciding the characters and plot: Deciding the characters and plot for a doujin novel is crucial. You need to create a unique image for the character and design an interesting plot to interest the reader. In the process of writing, one needed to pay attention to the interactions and emotions between the characters, as well as the development and turning of the plot. 3. Maintain Originality: Doujinshi novels should maintain their original nature and avoid using elements that already exist in the original work. If you need to use certain elements, you need to indicate the source when you use them and ensure that the elements do not have a negative impact on the story. 4. Use appropriate language and style: Doujinshi novels should use appropriate language and style to be different from the original. You need to use a language and style that is not in the original to create a unique story world. At the same time, he had to pay attention to the language and rhythm to make the story flow smoothly and naturally.
