Hermione hated Divination, which she thought was an "imprecise" subject, and had even given up on Professor Trelawney's elective. She was also afraid of being laughed at for her intelligence, of being expelled, of being told by Professor McGonagall that she had failed all her subjects. She was also terrified by how Snape had mocked her for having huge teeth after Malfoy cursed her. At first, she thought it was humiliating for Malfoy to call her "Mudblood"(but she was able to handle it better). Harry Potter and the Prisoner of Azkaban wasn't enough.

Hermione hated Luna mainly because she thought she was a bit of a weirdo, because Hermione disliked things like divinations that were unclear and illogical, and Luna believed in a lot of conspiracy theories. Hermione had also said that Luna's father's writing was rubbish, that Luna was ignorant, and that she had repeatedly tried to persuade Luna to give up her ridiculous ideas, but had failed. Luna thought Hermione was 'overly bigoted' and Hermione thought Luna was 'gullible'. Harry Potter and the Sorcerer's Stone was not enough. Everyone, please click to read the novel!
There could be a psychological aspect to it too. Some fans might enjoy writing or reading about conflict. Draco and Hermione are both strong - willed characters. Their clashes can create a lot of drama and tension. Fanfiction writers might use this 'hate' concept to explore darker themes, like prejudice (since Draco has some prejudices against Hermione's blood status) and the power struggle between different magical ideologies that their characters represent.
Perhaps in the fanfiction world, there are some misunderstandings. Molly could have accidentally said or done something that Hermione misinterpreted. Maybe Molly made a comment about Hermione's Muggle - born status in a way that Hermione took as offensive, even if it wasn't meant that way. This could easily plant the seed of hatred in Hermione's mind.
Maybe Lily has a very different view of the characters. She might think the fanfiction misrepresents Hermione in some way that she doesn't like.
Well, in some fanfictions, Sirius might be depicted as hating Hermione due to misunderstandings. Maybe he misunderstands her intentions or actions. For example, if Hermione is shown as being too strict with the rules in a story, Sirius, who has a rebellious streak, could resent that.
In fanfiction, the relationship between Hermione and Draco can be quite complex. Some fanfictions explore a love that blossoms from their initial hate. They might be forced to work together on a project, and through that, they start to see each other in a new light. Their different backgrounds in Hogwarts, with Hermione being a Gryffindor and Draco a Slytherin, add an extra layer of tension and intrigue to the relationship.
Well, in some fanfictions, Hermione might hate Bella because their personalities are so different. Hermione is studious, logical, and a fighter for justice. Bella, on the other hand, is often portrayed as more passive and overly focused on her romantic relationships. Their different values and ways of approaching life could lead to Hermione's dislike of her in fanfiction.
In some fanfictions, Hermione might be portrayed as hating Ron to create a new and different plot dynamic. Maybe the author wants to explore an alternative relationship path for Hermione, or they could be trying to add more drama by having her oppose Ron, who she is typically friends or more with in the original series.
Maybe James has a very different view of the original relationship between characters in the story. He might think that fanfiction distorts the essence of the original story and characters, especially when it comes to Hermione. He could be a purist who only likes the original portrayal and doesn't like the various interpretations in fanfiction.
You need to understand the characters well. Draco is proud and often tries to prove himself. Hermione is intelligent and doesn't tolerate injustice. Use these traits to fuel their hate. You could create situations where their goals directly oppose each other. For instance, if there's a school competition, Draco might try to cheat Hermione out of winning because he hates her so much. Also, don't forget to show the reactions of other characters to their feud. It can add more depth to the story.
