In some fanfictions, Harry might be angry with Ron and Hermione if he feels they are keeping secrets from him. For example, if they discover something important about Voldemort's plans but don't share it right away, Harry could get angry. He's used to relying on them and when that trust is broken, even if it's a misunderstanding, his anger can flare up.
Perhaps in the fanfiction, Ron and Hermione start to side with a new group or ideology that Harry doesn't agree with. For instance, if there is a new magical order emerging at Hogwarts and Ron and Hermione believe in its principles but Harry sees it as dangerous or wrong, it could lead to his anger towards them. Harry has always been the one to lead their little group in many ways, and this divergence could be a source of conflict.
Maybe he's read too much of it and found the plots repetitive. Fanfictions often follow certain patterns, and after a while, it can get boring.
A major reason could be differences in their approaches to fighting the dark forces. Maybe in the fanfic, Hermione wants to use a more diplomatic and academic approach, Ron is hesitant and just wants to follow the status quo, and Harry wants a more direct and action - based approach. Their inability to reconcile these differences can lead to Harry being angry. For example, when they are planning how to deal with a new dark wizard threat, their arguments and lack of compromise can make Harry frustrated and angry with them.
Some writers might create such fanfiction for the shock value. They want to break the established strong friendship in the original series to get readers' attention.
Perhaps Harry hates Ron and Hermione fanfiction because it can create false impressions. In the real world, their relationship is based on deep friendship, loyalty, and shared experiences. Fanfiction might deviate from this by adding out - of - character scenarios or relationships. Harry, who has been through so much with them, might not like seeing their story being told in a way that doesn't ring true to what he knows.
It might be because of a misunderstanding. In some fanfics, a false rumor could spread about Harry. Ron and Hermione, believing it to be true, might decide to distance themselves from him. Say, there's a rumor that Harry is involved with dark magic in some way, and they, being the 'good guys', think they need to stay away.
Well, it's simple. In the fanfiction world, Ron is sometimes portrayed as jealous because Harry is the famous 'Chosen One' and Hermione is super - intelligent. When they spend time together, Ron may think they are forming a clique without him. He's also a bit insecure, and seeing Harry and Hermione's camaraderie might make him fear that he's not as integral to their group as he wants to be. So, that jealousy pops up.
In fanfiction, Hermione might choose Harry over Ron because Harry often has a more heroic image. He is the Boy Who Lived, and his adventures are often more central to the main plot. Hermione could be attracted to his leadership qualities and the fact that he always seems to be at the heart of the action.
Well, they might be too caught up in the real events of their wizarding world. Fanfiction often takes creative liberties that could seem far - fetched to them. They've lived through the real Harry Potter adventures, so the made - up stories in fanfiction just don't seem believable.
In fanfiction, Ron might be portrayed as possessive of Hermione because in the original series, he has deep feelings for her. He may fear losing her to others, like Harry or new characters in the fan - created scenarios. His insecurities about their relationship could lead to possessive behavior.
Maybe it's because he has deep, unexpressed feelings for Hermione in the original story. Fanfiction allows him to be in different scenarios with her that he might have secretly desired in the real plot.
