This is probably a silly question, but please bear with me;; Most of my stories are very short and character-driven, with very loose plotlines. I've always been more interested in characters than big, elaborate plots (which are all fine and dandy, too, don't get me wrong). I guess this is just because I really like people? But, recently, I came up with this idea for a longer piece, with a somewhat complex storyline - complex in comparison to what I'm used to writing, anyway. The main story is more or less thought out, and I'm pretty excited about it. I've also got a vague idea of the main characters' personalities, and I know they'll become more developed as I write, so I'm not too worried about that. The thing I am worried about, though, is their relationships. Ideally, the two main characters become very close friends, even though one is hiding something from the other. I'd like people to care about the relationship, so when freaky stuff starts going down, their concern for each other actually means something, and at least some of the readers will actually care. What I'm saying is, I wanna write a rad bromance What I'd like to avoid is something like Dune - it's got a good plot and interesting characters, but their relationships, at least in my opinion, aren't very strong. For the most part, everyone seems to just be hanging around each other, and there aren't any connections that I actually care about. I mean, I love Paul and Chani to death, but I don't care much for their relationship. The only hint that they're even a thing is that Chani calls him "beloved" sometimes. (On a side-note, I'd be lucky if my writing is even halfway as good as Frank Herbert's. This is literally my only crit of Dune.) On the flip-side, I don't want the character relationships to interfere with the storyline too much, or feel like pointless filler. I don't want the readers to suddenly go, "What the hell are you guys doing? You're supposed to be hunting aliens. Hurry up!" Or something like that. My question to the more experienced writers out there (ie, everyone): How do you find a balance between your characters' relationships and your main storylines? How can I tell if I'm focussing too much on one over the other? Thanks, y'all.
