In this fanfiction, it could be that Ron has an initial unfriendly encounter with Harry. Perhaps Ron is jealous of all the attention Harry gets from the start. This causes Harry to be put off and decide not to befriend Ron. Harry then goes on to find other allies among the students who are more welcoming and less envious of his fame.
One possible storyline could be that Harry is sorted into a different house than Gryffindor and thus doesn't cross paths with Ron as much. He might form closer relationships with students from his new house, like Hufflepuff or Ravenclaw. This would lead to a whole new set of adventures and friendships for Harry that don't involve Ron at all.
It could become closer. Without Ron as a third party, Harry and Hermione might rely more on each other. They would have more one - on - one study sessions and adventures, which could strengthen their bond.
One possible storyline could be that Naruto decides to focus on traveling the world instead of becoming Hokage. He could use his skills to help people on a more individual basis across different villages. He might learn new jutsu from various shinobi cultures and become a sort of wandering hero.
Perhaps there were some secrets that Ron was keeping from Harry. In the wizarding world, secrets can be a big deal. If Ron had a secret related to his family or some other important matter and Harry found out about it in a way that made it seem like Ron was hiding something bad, it could lead to Harry not trusting him. Also, Ron's friendship with other characters might make Harry jealous or suspicious. If Ron was getting closer to someone Harry didn't trust, it could spill over and make Harry question Ron's loyalty to him.
Maybe Harry thinks fanfiction often distorts the real relationship between him and Ron. He values their genuine friendship and doesn't like the fictional and sometimes over - the - top interpretations in fanfiction.
Well, it could be that in the fanfiction, Ron made a mistake that had long - lasting consequences for Harry. Maybe Ron accidentally revealed one of Harry's big secrets that put Harry in danger. So, Harry is unable to forgive Ron as it has changed his life in a negative way.
One possible reason could be miscommunication. Maybe Ron said something that Harry misinterpreted, leading to the distrust. For example, if Ron made a joke about Harry's abilities in a time of stress, Harry might take it the wrong way.
It could also be due to a long - standing pattern of behavior. If Ron had been constantly critical or undermining of Harry in the fanfiction, Harry might reach a point where he just can't forgive. Say Ron always made fun of Harry's decisions in front of others, which gradually eroded Harry's trust and patience.
It could be due to a misunderstanding that got out of hand. Ron and Hermione might have been involved in something that Harry misinterpreted as a sign of their disloyalty. For instance, they were secretly working on a project that Harry thought was against him, but in reality, it was for his own protection. However, because of the lack of communication, Harry's anger and unwillingness to forgive grew.
He can simply choose to ignore it. If he doesn't like the fanfiction, he doesn't have to read or engage with it at all.
Another reason could be personal insecurities on Harry's part. Harry has been through a lot and might be over - analyzing Ron's behavior. He could be projecting his own fears onto Ron. For example, if Harry is worried about being betrayed again like he was by some people in the past, he might start to doubt Ron even without solid evidence.
