Sure. There are a lot of fanfictions based on 'Pride and Prejudice' that follow the hate - to - love trope. Mr. Darcy and Elizabeth Bennett start off with a strong dislike for each other. Another example could be from some superhero fanfictions where two heroes from different teams initially hate each other but then fall in love. For instance, in some X - Men fanfictions, Wolverine and Storm might be portrayed in such a relationship.
One example could be from the 'Harry Potter' fandom. Some fanfictions might explore a hate - to - love relationship between Draco Malfoy and Hermione Granger. In the original series, they are rivals, but in fanfiction, authors can take this and turn it into a romantic relationship. Also, in the 'Star Wars' universe, there could be fanfictions where a Jedi and a Sith start off hating each other but end up in love. It's all about taking the existing characters and their relationships and flipping them into a love story from a hate - filled start.
There are many examples in the world of anime fanfiction. For example, in 'Naruto' fanfiction, Sasuke and Sakura's relationship could be re - imagined in a hate - to - love way. At the start, Sasuke is cold towards Sakura, but fanfiction writers can create scenarios where their relationship changes. Similarly, in 'Fairy Tail' fanfiction, characters like Natsu and Lucy could be written in a hate - to - love relationship. Maybe Natsu accidentally causes trouble for Lucy a lot at first, and she hates him for it, but then things change over time.
