When writing stories, there's always that scene where you want to introduce a character, but at times, this can be hard in the moment. I would think this because I write all the time, and the most stubborn part of the story's progress is the introduction of a character. Do you struggle with this? If so, which characters do you struggle with the most? I know for a fact that I do, especially with secondary or primary characters, occasionally even the main characters or those who appear only once or twice.
