One possible plot is that a magical object affects Harry and Ron's minds, making them bully Hermione. Hermione, at first, is heartbroken. But she then uses her intelligence to find a way to reverse the object's effect. Meanwhile, she also stands up to them, showing her strength. When the boys are back to normal, they are ashamed of their actions and have to make amends. This could also lead to a deeper exploration of the importance of true friendship and not being easily influenced by external factors.
Well, it's possible. Fanfiction is a vast and diverse genre. Such a fanfiction could start with Harry and Ron's out - of - character bullying of Hermione, perhaps due to some external influence like a dark magic spell gone wrong or a misunderstanding. But then, it could develop into a story of redemption where they come to their senses. It could also explore Hermione's strength in the face of such bullying, highlighting her intelligence and courage as she tries to figure out why her friends are acting this way and how to make them stop.
It could be that Ron and Hermione abandon Harry due to a prophecy that they misinterpret. They believe that by being with Harry, they will bring doom to the wizarding world. So they go into hiding. Harry, on the other hand, is determined to change the course of the prophecy. He embarks on a journey to find the truth behind it, all while feeling the pain of his friends' desertion. He has to fight against dark forces that are taking advantage of the situation.
In such a fanfiction, it might be that Harry and Ron are influenced by a powerful dark spell. This spell makes them see Hermione as a threat, so they abandon her. Hermione then has to find a way to break the spell's influence on them while also dealing with the loneliness and danger she's now in. She could seek help from other Hogwarts students or even some friendly magical creatures.
A possible plot could be that the Muggle teacher is being targeted by a dark wizard who wants to use the teacher's knowledge of Muggle technology for evil purposes. Hermione, Ron, and Harry find out and decide to protect the teacher. They have to hide the teacher in the wizarding world and teach them basic self - defense spells.
Perhaps Hermione starts a secret club or organization for students who are interested in advanced magic. As Ron and Harry ignore her, she pours all her energy into this. The club gains popularity and starts to influence the way magic is taught at Hogwarts. Ron and Harry, seeing the positive changes Hermione is making without them, start to feel guilty and try to make amends.
Perhaps Harry overhears a very private and heartfelt conversation between Ron and Hermione. He might realize that their relationship has deepened in a way he hadn't noticed before. This could make Harry feel a bit left out at first, but then he would probably be happy for them. He could also use this new knowledge to be more understanding of their actions and decisions in the future.
Adventure is also a big theme. They go on all sorts of adventures in the wizarding world, and fanfiction writers like to continue that. Maybe they go on a new quest to find a lost magical artifact or solve a mystery that was left unsolved in the original books. It gives the characters a chance to show their skills and grow even more.
It also shows the freedom and diversity in fanfiction. While it might not be in line with the original spirit, it allows for different creative ideas to be explored. However, it can cause some division within the fan community between those who support this new take and those who firmly oppose any deviation from the original relationships.
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.
Well, it could be about their simple daily life at the Burrow. Maybe they are helping Mrs. Weasley with the housework, and there are some cute and funny moments between them, like Ron accidentally messing up a spell while trying to assist Hermione in cleaning the dishes.
