One reason is that they want to explore a different narrative. The Harry Potter series has a huge fan base, and some fans feel that the relationship between Harry and Hermione could have been developed in a romantic direction. So, they write fanfics to fulfill that creative urge. They can also add their own twists and turns to the relationship, like having them face unique challenges together that bring them closer romantically. It gives fans a chance to expand on the world and characters they love in a new way.
Some people like these fanfics because it offers a different take on their relationship. In the original books, their relationship is mainly platonic, so seeing Harry flirt with Hermione is a fresh and exciting idea.
Some people write it because they feel there was an underlying romantic tension between Harry and Hermione in the original series that was not fully explored. They want to explore that potential relationship through their own stories.
Some people write it because they see a potential romantic connection between Harry and Hermione that wasn't explored in the original books. They want to fill that gap and create their own version of the story where the two characters get together romantically.
Well, for one thing, it's about creativity. Fans want to take the well - loved characters of Harry and Hermione and put them in different scenarios where love can develop. Also, some fans might feel that their relationship could have added another layer of depth to the overall story. It gives a chance to rewrite or expand on the existing story in a new and exciting way. They can explore how their different personalities would interact in a romantic relationship.
They might write such fanfics to give Harry a new adventure. After all the events in the original books, his story doesn't have to end in Britain. It's a way to expand on his character and see how he would react in different situations outside his familiar homeland.
Stress and danger can also be reasons. When facing a powerful dark wizard or a difficult situation at Hogwarts, the pressure can get to them. Harry may yell out of frustration at not being able to find a solution quickly, and Hermione might yell back as she tries to keep him calm and rational. In a fanfic, this can create a lot of emotional turmoil and keep the readers engaged.
Some writers might write it for shock value. They want to create a scenario that is completely unexpected and different from the norm. By having Hermione cheat on Harry, it throws the familiar relationship dynamics out the window and grabs the reader's attention.
Authors write 'Hermione cries' fanfics to explore her emotional depth. Hermione is often portrayed as strong, but crying shows her vulnerability, like in real people. It adds a new dimension to her character.
Some people might write it because they want to explore alternative character dynamics. They may feel that Hermione's character in the original was too perfect and want to see how the story would change if she had more flaws.
Some people might write it because they simply don't like Hermione's character in the original books. Maybe they find her too perfect or too overbearing and want to create a different version of the story where she's not so dominant.
