Maybe in that fanfic, there are misunderstandings between Harry and the Weasleys. For example, they might have had an argument over something like magic use or family values that led Harry to dislike them.
In this fanfiction, perhaps there's some miscommunication. Maybe the Weasleys' boisterous nature is misconstrued by Harry. For example, their large family dynamic might be overwhelming to him at times, which could be a reason for the 'hate' in the fanfic.
Well, in the original series, the bond between Harry and the Weasleys is one of the central elements that make the story so heartwarming. They support each other through thick and thin. In the 'harry potter hates the weasleys fanfiction', this is turned on its head. The fanfiction might change the way we see Harry's character development. In the original, the Weasleys play a big role in shaping Harry into the person he becomes. But in this fanfic, with the hate relationship, it would mean a completely different path for Harry's growth and his understanding of family, friendship, and the wizarding world.
The fanfiction goes against the character development in the original. In the books, Hermione grows to love and respect the Weasleys as she spends more time with them. But in this fanfiction, the hatred is a complete contrast to that natural progression of relationships.
It could be that in the fanfic's plot, the Weasleys have some actions that go against Hermione's principles. Say, they might be involved in some pranks that have negative consequences for Hermione's studies or personal goals, and that's why she hates them.
Well, in the original, Harry is very close to the Weasleys, especially Ron. They go through many adventures together. But in this fanfic, if Harry hates them, it changes everything. It means that all the shared experiences and the bond that was built over time in the original no longer exists in this fanfic. It's a radical change from the positive and warm relationship they have in the original story.
One possible reason could be that Harry has post - war trauma. He might have seen so much death and destruction during the war that he doesn't want to bring his darkness and pain to the Weasleys. He may think that staying away is a way to protect them from his own emotional turmoil.
At first, the Weasleys might try to reach out to Harry. But as he continues to avoid them, they could start to feel rejected. This might lead to some resentment building up, especially among the younger Weasleys who don't understand why Harry is acting this way. For example, Ron might be really frustrated as he considered Harry one of his best friends.
One possible reason could be jealousy. Maybe she sees the Weasleys as getting things too easily in the wizarding world compared to her own hard - earned achievements. For example, they have a big family support system that she lacks, and she might envy that.
