Well, perhaps in this fanfiction, Harry has been through so much that he decides to isolate himself from everyone. He might be tired of the constant danger and the expectations placed on him. So he shuts out his friends like Ron and Hermione, and just focuses on his own inner journey, maybe to discover some new magic that he believes can only be found in solitude.
The other students at Hogwarts would also be affected. For example, Neville, who looks up to Harry. If Harry ignores everyone, Neville might feel lost. Ginny, who has a special connection with Harry, would be deeply hurt. And the teachers like Snape, who has a complex relationship with Harry, would also be impacted. Snape might be secretly glad at first, but then realize that Harry's isolation could be a sign of a bigger problem in the wizarding world.
His closest friends like Ron and Hermione would probably be the most affected. They are used to having Harry around and relying on him. His sudden ignoring would leave them confused and worried.
It can divide the fandom. Some fans who love the original dynamic between Harry and Ron might be disappointed or even angry at this deviation. They might see it as ruining the essence of their friendship.
One possible reason could be a plot device to create drama. By having Harry ignore Ron, it can lead to tension within their friendship, which is a central relationship in the original series. This can then drive the story forward as they have to resolve this issue.
Well, it could create a lot of tension. If Harry ignores everyone, it might lead to misunderstandings. His friends might feel left out or hurt, which could drive a wedge in their relationships. This in turn can change the whole dynamic of the group. For example, they might not be as united when facing challenges, and it could also lead to some of them trying to figure out why Harry is acting this way, adding a mystery element to the plot.
Well, some fans might create such fanfictions to explore different relationship dynamics. Maybe they want to show a more complex side of Harry, like he's so focused on his fight against Voldemort that he unintentionally ignores Ginny. It could also be a way to add some drama and angst to the story.
Maybe he got some kind of curse. In the Naruto universe, there are all sorts of dark magic and curses. If he was cursed, it could make him withdrawn and cause him to ignore everyone.
Probably not as popular as the regular positive or canon - compliant Harry Potter fanfiction. Most fans love the characters and the world, so bashing everyone might not appeal to the general fanbase.
Well, this kind of fanfiction might be an interesting take on the character. It could explore a darker side of Harry Potter that we don't often see in the original series. Maybe the author wants to show how all the pressure and trauma he has endured could lead to a more cynical view of those around him.
