First, there's the obvious initial hostility between the main characters. This creates a lot of tension that drives the plot forward. Second, the build - up of sexual tension is a key part, which is what makes it'steamy'. Third, there's usually a moment of realization or a change in circumstances that makes them see each other in a new light and start to fall in love.
One popular one is 'A Court of Thorns and Roses' series. The relationship between Feyre and Rhysand starts off with animosity as they are from different and often opposing groups. Their interactions are filled with tension that gradually turns into passion.
'Pride and Prejudice' by Jane Austen can also be considered in this genre. Elizabeth and Mr. Darcy start off with a strong dislike for each other. The novel beautifully develops their relationship over time, and while it may not be as 'steamy' in the modern sense, the underlying passion is there. There are many adaptations that bring out the romantic and somewhat passionate elements more vividly.
Typically, they start with a lot of conflict. For instance, in 'Kiss Quotient', Stella and Michael have different outlooks and purposes at the start. Their clashes create that initial 'enemies' dynamic. Then, through forced proximity, like having to work together or live in the same place, they start to see each other's true selves.
One important method is through dialogue. As they start to talk more, they begin to understand each other's motives and personalities. In some novels, a gradual revelation of the characters' true selves plays a big role. For instance, the 'enemy' might show a vulnerable side that the other character didn't expect. This can break down the barriers between them. Also, the setting can contribute. If they are in a new and unfamiliar place together, it can force them to depend on each other and change their relationship dynamic.
The novel 'Aristotle and Dante Discover the Secrets of the Universe' also has elements of this trope. Ari and Dante meet and initially don't really understand each other. But over time, their connection deepens into a powerful and loving relationship.
Often, these novels also deal with themes of acceptance, not just of their relationship but also of themselves. Since they start as enemies, they have to overcome their own prejudices. In a gay romance context, this can also be related to coming out and dealing with society's views, which adds depth to the story.
The 'Outlander' series by Diana Gabaldon also has an enemies - to - lovers aspect. Claire Randall, a World War II nurse, is transported back in time to 18th - century Scotland. There, she meets Jamie Fraser. At first, they have misunderstandings and conflicts. Jamie is part of a Scottish clan that has its own issues and Claire is an outsider. But over time, their relationship develops into a passionate love affair.
The main reason is the tension. The initial dislike or rivalry creates a lot of emotional tension that is exciting to read. It's like watching two opposing forces gradually come together.
One popular 'enemies to lovers' romance novel is 'Pride and Prejudice' by Jane Austen. The initial animosity between Elizabeth Bennet and Mr. Darcy is well - known. Another is 'The Hating Game' by Sally Thorne, which features two coworkers who can't stand each other at first but gradually fall in love.
