Why would someone create 'hermione granger is harry's slave fanfiction'?

Definitely not. The idea is completely wrong. Hermione is Harry's friend and they have a relationship based on mutual respect, support, and shared adventures. Fanfiction like this is a misrepresentation of the characters. Hermione is a strong female character with her own agency, and reducing her to a slave in fan works is inappropriate.

Some might write it to explore a different side of the characters. Maybe they want to see how the story would change if there was conflict between Hermione and Harry instead of their usual friendship.

One reason could be for shock value. Writers might want to create a very different and unexpected story line. In some cases, it could be a dark exploration of what could happen if a character went completely off the rails. However, this goes against the essence of the original series where they are friends.

Perhaps he has feelings for Hermione that he doesn't know how to handle. Harry might be afraid of these new emotions and so he acts cold as a defense mechanism. In some fanfictions, there could be a plot device where Harry has seen a vision of the future that makes him think being close to Hermione is dangerous for her. So, in an attempt to protect her, he acts cold. It could also be that there is some external pressure, like from other students or even teachers, that makes Harry think he should distance himself from Hermione, and this shows as cold behavior.

There are many great fanfictions about Harry Potter and Hermione Granger. Some focus on their adventures during the Hogwarts years that were not shown in the original books. For example, there could be a story about them solving a mystery in the Forbidden Forest on their own. These fanfictions often explore their friendship in more depth and show how they rely on each other's skills and knowledge.

It differs mainly in the role assigned to Hermione. In most other fanfictions, she is often depicted as a heroic figure or a brilliant student. Here, as a 'house slave', her focus is more on the domestic aspects of the wizarding world, which is quite different from her typical roles.

Maybe Hermione chooses Ron over Harry in the fanfiction. Since Harry has deep feelings for Hermione, this would be a crushing blow to him.

One reason could be to explore alternative storylines. The original 'Harry Potter' series has a set path for the relationships, but fanfiction writers like to break the mold. Maybe they think Hermione and Ron's brother could have an interesting dynamic that wasn't explored in the books. Another reason could be to add more drama. A relationship like this would surely cause a stir among the characters in the wizarding world, and it makes for an exciting plot.

In many fanfictions, Hermione Granger's family plays important roles. Her parents, who are dentists in the original series, might be depicted with more magical involvements in fan stories. For example, some fanfictions could explore how her parents adjust to the wizarding world after Hermione reveals her magical abilities to them more fully. This can add new dimensions to Hermione's character as well, as her family background and their relationship can shape her actions and decisions within the fan - created plots.

It could be for the sake of realism. In a magical world full of danger and adventure like Harry Potter's, characters are bound to get sick or have physical reactions. Hermione is a very studious and often overworked character, so it's not far - fetched to imagine her pushing herself too hard and getting ill.
