How to Write a Swoon-Worthy Sweet Romance Novel

How to use this list:

As I’m brainstorming, I like to look over my list of tropes and find tropes that work well with each other. I list out tropes that introduce conflict and either repel the couple or provide that adhesive that sticks them together. I find a few that I feel work well together and complement each other. For example, the performer trope works well with the social class trope and the opposites attract trope. After I find tropes that I like, I weave them into a plausible storyline and add the personalities of the characters.

Before using a trope, I highly recommend researching and reading some romance novels with that trope so you understand the expectations your readers will have if you use it.
