it is ok for two people to write a novel. However, if two people want to accept the dragon, they need to consider the tacit understanding. If you just want to write a novel, you can draw up the topic and theme by two people and then slowly extend it. Different people are responsible for different aspects. If you want to write well, you need not only the communication between two people, but also the innovation of the idea and the rationality of the plot. There may be friction in the process of writing, which must be tolerated.
