There is no definite answer to this question because the length of a romance novel depends on many factors such as the complexity of the story, the depth and breadth of the characters, the ups and downs of the plot, and so on. In addition, romance novels were different from other types of novels. They usually needed to show a rich emotional description and emotional twists and turns, so the number of words should not be simply calculated in units of ten thousand words. Generally speaking, a good romance novel could be written in hundreds of thousands of words or even more. However, the most important thing was to let the readers feel the emotional depth and exquisiteness of the novel instead of simply pursuing too many words. Therefore, when writing a novel, one had to decide the length of the novel according to their own writing style and the needs of the readers to create a truly valuable work.
