A romance without conflict is just a pleasant afternoon, not a story. To keep readers engaged, a storyline typically weaves together three types of tension:

The greatest romantic storylines understand that tension is not an obstacle to love; it is the forge of love. Without friction—without missed phone calls, terrible timing, differing life goals, or the simple terror of vulnerability—you don’t have a relationship. You have a greeting card.

Whether it’s the primary focus of a "Romantasy" novel or a subtle subplot in a gritty thriller, are about the transformative power of connection. When you write about two people finding each other, you aren't just writing a love story—you’re writing about what it means to be human.

Ensure both characters have their own lives, goals, and personalities outside of the relationship. A character whose only purpose is to be a "love interest" rarely feels three-dimensional.
