Let’s be honest, even when the main plot of a story isn’t romance, it still will often be included as a subplot to the story. Similar to the questions you’d ask when world building or developing individual characters, asking certain things of your character pairings is a good way to further develop your couples and make them realistic and believable to the reader. These are the types of questions that can be helpful to figure out how good a match your characters are. Of course, not all these questions need to be answered in the story itself, but it’s good information to have in order to better understand your characters.
Questions to ask about your character pairings:
What do they like about each other?
What do they not like about each other?
How did they meet?
How long have they known one another?
How open are they about their love?
Is their attraction superficial or very deep?
What do they share in common?
Who initiated the relationship?
How do other characters view their relationship?
How much does their relationship affect he story?
Are they casual or serious in their relationship?
Are they happy in their relationship?
How much time do they spend together?
