Nesting

 Often neglected as a technique in a romance novel is showing an adult male nesting. If he's excited to prepare a room for a new baby, a mother-in-law, lol, or more to the point the lady who is about to move in and needs an office, the writer has another opportunity to enrich the story and make the characters more real. One thing I see often is the male running around trying to straighten up. Not quite the same flavor, but he gets points and the reader will wonder if he'll just backslide back into slobbery.
