Is love the driving engine of a story, or just an accessory to a bigger plot? This episode maps the emotional markers that define a romance — desire, mutual change, and the promise of a future — and shows how they differ from books where a relationship is present but not central. Using beloved classics and BookTok favorites as touchstones, we offer readers an easy way to tell whether a title is romance-first, plot-first, or somewhere in between. Perfect for anyone who loves talking tropes and debating which books make your heart the main character.
