Melissa, yes, I agree. Most of the romances I read that don’t engage my interest are because there’s no conflict between the two MCs. There’s nothing keeping them apart except some outside influence. That’s fine if the story is a mystery, but not if it’s a romance.
One reason why romance is more complicated to write than most people realize is because of the need for a conflict between the two MCs. It has to be serious enough to keep them apart but also resolvable. Very challenging to write!
