One possible reason could be that Hermione might be too overbearing in her studies and constantly nags Harry about his schoolwork in the fanfiction. This could annoy Harry and make him mad.
Maybe in the fanfiction, Hermione makes a decision without consulting Harry, something really important like a plan to deal with a dark wizard threat. Harry might feel left out and angry because of that. For example, if she teams up with other characters and leaves Harry in the dark, it would surely make him mad at her.
One possible reason could be a misunderstanding. Maybe there was a miscommunication about something important, like a plan to fight against the Dark Arts. For example, if the Weasleys accidentally left Hermione out of a crucial part of the plan, she might be very angry.
Maybe Dumbledore made a decision that put Harry in great danger without his knowledge. For example, sending him on a dangerous mission without proper preparation.
It might be that there was some sort of misunderstanding. For example, a rumor spread that Harry was getting too close to one of his female colleagues at work. Ginny, being a fiery character, got mad without really knowing the truth. In fanfic, these kinds of misunderstandings are often used to create drama.
One possible reason could be that he's worried about Ginny's safety during the pregnancy. He might be overprotective and his concern comes out as anger.
Maybe Snape made a snide comment about Hermione's intelligence or her Muggle - born status. Snape has a rather acerbic tongue, and if he said something derogatory about Hermione's abilities or her heritage, she would surely be furious. After all, Hermione works extremely hard to prove herself in the wizarding world and any attack on her intelligence or background would be a big blow.
She could be disgusted if the fanfiction has really bad writing. Poor grammar, inconsistent plotlines, and shallow character development can make it seem like the writer doesn't respect the source material or the character. Also, if the fanfiction includes a lot of OOC (out - of - character) moments for her friends, like Ron being overly cruel or Harry being stupid, it might make her seem disgusted within the context of the story.
She could also lie to gain an advantage in a situation. Maybe there's a competition or a mystery they're trying to solve, and she thinks lying to Harry will give her the upper hand. For example, if they're competing to find a hidden magical object, she might lie about where she's looking to throw him off.
One possible reason could be jealousy. Maybe Hermione gets jealous of Harry's popularity or his special connection with other characters. Another reason might be differences in their approaches to solving problems. Harry could be more impulsive while Hermione is more methodical, leading to clashes. For example, in a situation where they need to rescue someone, Harry might want to rush in without a proper plan, but Hermione would insist on having a well - thought - out strategy first.
Well, in 'harry hates hermione fanfiction', it could be that the writer is trying to show how misunderstandings can lead to such extreme emotions. For example, perhaps there was a miscommunication about a spell or a magical event that made Harry wrongly think Hermione had betrayed him. Or it could be a way to explore how different personalities might clash more severely than shown in the original series, like Harry's impulsive nature conflicting more with Hermione's logical thinking.
It could be due to jealousy. Perhaps Ginny has been spending a lot of time with another character, and Harry misinterprets their relationship, leading to his anger. In fanfiction, the writers often play with such emotions to create drama.
