I don't believe they can get past the titles. Then the story ends. Love means patience. Love means respect. Love is commitment.
Love is unselfish.
Love also is what gets you through the days you don't like each other very much. Love involves deference towards each other. Maybe I'll get up the gumption to write a realistic romance someday. The hero will be a hard-working man who's doing the best he can for his family. He'll be wide in the shoulders and slim in the hips.
