Plot and Character: You Can’t Separate Them.
According to Google, a plot is: “the main events of a play, novel, movie, or similar work, devised and presented by the writer as an interrelated sequence.”
Stuff happens in your romance, whether it’s a short story, a novella, or a novel. However, unlike life, where stuff happens all the time, and most of it means nothing, in your story, everything happens for a reason, and everything means something. Everything is “interrelated”, and happens for a reason.
For example, let’s say that you have an important meeting first thing in the morning at work. You sleep in, burn your toast, your car won’t start, and you’re late. You have a horrible morning, but so what? The meeting starts late, you give your presentation, and your day goes pretty much as it always does, and you go home.
You could use a similar situation for your story, as long as you remember that everything has to mean something.
