In a Nutshell: Rose owns a flower shop. A handsome man comes to order a bouquet. Rose assumes it's for his girlfriend, but soon finds out it's for his sister. The next day he sends Rose some flowers along with an invitation to dinner.
Observations: It's not unusual for the plot of a Woman's World story to hinge on a misunderstanding such as the protagonist assuming the love interest is married or taken when he/she is really not. Rose's Roses follows that "formula." However, what sets this story apart is the epilogue paragraph in which the two get married. That occurs very rarely.
