I have two of the main characters in a short story I'm trying to develop, but I'm having trouble about how go on to creating supporting and minor characters. How can I go about doing this? Just the same way I did to develop main characters? I didn't want to do that as they are minor characters and not much will be revealed about them at all, but if I need to then I don't mind fully developing them as well. Any tips to go about this will be very helpful. Most of the time, I write short stories, usually about 5-10 pages and these short stories have only ever had two characters ever. They detail in how the characters are related to one another throughout and then go on about the actual plot, usually romances with tragedy or bad attempt at suspense. Because of this, I'm not used to having more than just the two characters. I do vaguely add other characters for a moment or so, so its not like they are entirely alone in my story's world. But again, I never had any real supporting or minor characters that help with actual plot.
