It could be that Ron is having a bad day or going through some personal issues. And instead of dealing with them in a healthy way, he takes it out on Hermione. For example, if he's feeling insecure about his place in the group, he might lash out at her.
One possible reason could be that in the fanfiction, Bill might be depicted as more mature and worldly compared to Ron. Hermione may be attracted to his experience and the different perspective he can offer.
Well, Hermione might choose to simply ignore Ron at first. She's got a lot on her plate, like her studies and helping Harry. But if he continues to be a git, she'd probably use her intelligence to outwit him in some way. Maybe she'd come up with a really clever comeback that would leave him feeling stupid. She could also choose to distance herself from him, like spending more time with other friends or focusing on her own projects.
Another aspect could be Ron's jealousy issues. In the original story, Ron sometimes gets jealous of Hermione's friendship with Harry or her academic achievements. In fanfiction, this jealousy could be exaggerated to a point where Hermione can't tolerate it anymore and thus is written as hating him. For example, if Ron constantly tries to undermine her success out of jealousy, it would be a valid reason for her to develop strong negative feelings towards him.
It could be that Ron has his own insecurities. He might feel inferior to Hermione in terms of intelligence and magical abilities. By trying to control her, he hopes to feel more powerful or important. For example, if Hermione is always getting top grades and solving complex magical problems, Ron might think that by controlling her actions, he can somehow boost his own self - esteem.
It could be a way for writers to show their creativity. By taking a well - known relationship and flipping it on its head, they can create unique and unexpected storylines. Maybe they want to explore how Ron would react to Hermione's hatred and how it would change his character development. Also, some fans might have their own personal interpretations of the characters that deviate from the original, leading them to write such fanfiction.
One reason could be for the sake of creating drama. By showing Ron as controlling, it adds tension to the story. Another might be a misinterpretation of his character traits. If an author emphasizes his protective side too much, it could come across as controlling.
One plotline could be that Ron is lured by the promise of power. He betrays Hermione to join a dark wizard or group that offers him something he desires, like more status in the wizarding world. Another could be a love triangle gone wrong. If there's a new character who Ron fancies and this person convinces him that Hermione is standing in the way of their relationship, he might betray her.
It's wrong because it goes against the spirit of the original story. In the Harry Potter books, Ron and Hermione have a relationship that evolves from friendship to love. Abuse has no place in their relationship. It also sets a bad example for readers, especially younger ones who are fans of the series. We should be promoting positive relationships in fan - made content.
One reason could be that Hermione is a strong - willed character. In fanfiction, Ron might be depicted in a way that undermines her independence. She wants to be seen as her own person, not just as Ron's love interest.
One reason could be a divergence from the original character traits. In the original story, Hermione and Ron have a complex relationship with love and friendship. Fanfiction that misrepresents Hermione's feelings towards Ron might go against the essence of her character. Maybe the fanfiction portrays her as hating Ron in a way that doesn't fit with her growth and development in the official series.
