(This might go under plot development as well, but a lot of it is characterization, so...) In my story, there are two protagonists, and their roles in the story intertwine a lot with one another. It's a story that develops over the course of many years (from 12 yrs. - 22 yrs. of age), so I intended for both of them to consider each other as a romantic interest at one point or another (the girl considers this at 12 yrs., the boy at around 21 yrs.), although I thought it might just be better for them to stay as really good friends because romance isn't really the focus of the story, as it's a fantasy story. They banter a lot, and their personalities clash sometimes, like any relationship (friendship) out there but they really do care for one another. I, as the author, don't really want to put them together because I wanted to develop their characters as individuals, as opposed to being called x's boyfriend or y's girlfriend and I'm scared that if I put them in a romantic light, it will take away from their characters a bit. I also thought about giving them separate love interests over the course of the story, which can also pull away from the x and y being together bit. What are your opinions on writing boy/girl relationships that aren't romantic? And how would you write it without introducing romance into the mix?
