Two rivals or adversaries gradually develop romantic feelings as they uncover deeper layers of each other's character.
101 books with this trope
Enemies to lovers is the trope. Every other romantasy trope plays second fiddle. Two people who genuinely cannot stand each other, locked in opposition, slowly realising the real problem is that they want each other and don't know what to do about it. The best versions earn it. The relationship doesn't snap from hate to love in a chapter. It builds through a hundred small moments, each one a little more dangerous than the last.

It works because it forces character. You can't do enemies to lovers with two flat people. Both have to want something, both have to have reasons, and both have to be wrong in ways that make sense. The romance becomes a side effect of two strong personalities colliding for long enough that they start to understand each other. Sarah J. Maas figured this out with Feyre and Rhysand. Rebecca Yarros built Fourth Wing on it. Holly Black weaponised it with Jude and Cardan. The hate has to be real or the love means nothing.
The biggest failure mode is fake enemies. Two people who say they hate each other but never act like it, never make decisions that hurt the other, never have to choose between their goals. That's bickering, not enmity. The other failure is sudden capitulation, where one big confession dissolves all the conflict. Real enemies to lovers should feel like a slow surrender, with both characters resisting until they can't anymore.
If you've never tried the trope, A Court of Mist and Fury is the gateway drug. Then The Cruel Prince for the YA version with sharper teeth. Fourth Wing if you want the modern crowd-pleaser. The Serpent and the Wings of Night for darker stakes. From Blood and Ash if you want spice with your slow burn. Each of these handles the trope differently but all of them earn the moment when the walls finally come down.
