There could be a fanfiction where Ron and Hermione are influenced by a new group of friends or a new magical society within Hogwarts that looks down on Harry for some reason. They get so involved with this new crowd that they start to ignore Harry. However, Harry's own journey in this situation could be about finding new allies and proving himself in different ways, which in turn makes Ron and Hermione realize they made a mistake by ignoring him.
One possible plot could be that Ron and Hermione start to focus more on their relationship and their own personal growth, which leads them to unintentionally ignore Harry. They might get caught up in their studies at Hogwarts or in exploring their magical abilities further. For example, Ron could be working hard on becoming a better wizard in the areas he's not so confident in, like spell - casting accuracy. And Hermione might be delving deeper into ancient magic research. This causes Harry to feel a bit left out as he's so used to their trio dynamic.
It could be that Harry has been influenced by some external force. In fanfiction, there could be a new dark wizard or a magical object that is affecting his mind. This new influence might make him think that Ron and Hermione are in danger if he stays close to them, so he ignores them to keep them safe.
There are several possible reasons. It could be due to a misunderstanding about a prophecy or a magical object. For instance, if Ron accidentally breaks a magical heirloom that Harry believes could be important in fighting Voldemort, Harry might be so angry that he ignores Ron. Also, it could be related to Ron's family. If Ron's family does something that Harry disapproves of, like siding with the Ministry when Harry thinks they're wrong, Harry could start ignoring Ron.
One possible plot could be Hermione realizing that she and Ron have grown in different directions over the years. Maybe she's focused on her career in magic research and Ron is more into a laid - back life at the Burrow. Their different priorities lead to a rift that eventually results in divorce.
However, this could also lead to a strengthening of their relationship between Ron and Hermione. They would have to rely more on each other without Harry around. And when the truth behind Harry's ignoring them is finally revealed, it could either make their friendship with Harry stronger than ever as they work through the issues, or it could be so damaged that it's hard to repair.
One possible plot could be that Ron and Hermione suspect Harry is involved in some dangerous secret magic that could put him in harm's way. So they spy on him to find out more and end up discovering it's all a big misunderstanding. Maybe Harry was just trying to surprise them with a new spell he learned.
In some fanfictions, it could be a misunderstanding that spirals out of control. Hermione and Ron misinterpret one of Harry's actions. For instance, Harry might be trying to protect them in a secret way, but it looks like he's up to something bad. Their lack of trust then grows, and they end up betraying Harry, perhaps by not coming to his aid when he really needs them, which could have serious consequences for Harry.
One interesting plot could be the challenges they face in adjusting to the new law. For example, they might have to deal with sudden public attention and expectations. Another plot could be how they navigate their relationship while also fulfilling the requirements of the marriage law, like having to attend certain marriage - building events together.
Well, there are fanfictions where Ron and Hermione are tasked with bringing unity among different wizarding communities. Since the war has divided many, they use their influence and friendship to bridge the gaps. It's interesting to see how they handle the politics and different magical traditions. And then there are stories where they explore the non - magical world together post - war. It's a new experience for both of them and the author can play with their reactions to Muggle technology and culture, which is quite fun to read.
One possible plot could be how they deal with the reactions of their friends and family. For example, Harry might be shocked at first but then become very supportive. Another plot could involve their studies at Hogwarts. They would have to balance the challenges of pregnancy with their academic responsibilities, like Hermione still trying to ace all her exams while dealing with morning sickness.
One interesting plot could be Harry and Ron getting into a magical adventure together where they discover a hidden lemon grove with special magical properties. In this grove, they have to solve a series of puzzles to get out, all while their friendship is tested and strengthened.
