I'm planning out this story and I've realized that for a certain character's arc to really work he needs to become friends with another character who happens to be female. The first thing I'm worried about is making it feel like either is romantically interested in the other. It sounds kind of silly but I've noticed a lot of people just assume that if an important male character and an important female character are good friends then it means at least one of them is romantically interested in the other. So my first question is how should I handle this to avoid giving that impression. My second question has more to do with developing the relationship. I feel I understand both of the character rather well, but I'm still unsure on how their friendship should develop. I was wondering if anyone knows or has heard of any good exercises or worksheets for developing character relationships. I've seen quite a few character building exercises, and worksheets but I haven't seen any for character relationships.
