What would be the possible reasons in a 'Harry dumps Ginny for Hermione' fanfiction?

Yes, there are likely fanfictions with such a plot. Fanfiction writers often explore alternative relationship dynamics in the Harry Potter universe. However, this goes against the canon where Harry ends up with Ginny.

Well, some writers might do it to explore different character dynamics. Maybe they think there are aspects of Harry and Ginny's relationship that were not fully explored in the original books. By having Harry dump Ginny, they can dig deeper into the individual characters' personalities and how they react to a break - up.

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.

One possible reason could be the strong intellectual bond Harry has with Hermione. They've been through so many adventures together, solving mysteries and facing challenges. Their shared love for knowledge and learning might make Harry realize he has a deeper connection with Hermione compared to Ginny.

One possible reason could be miscommunication. Maybe Ginny feels neglected by Harry because he's so caught up in his own heroic deeds and doesn't pay enough attention to her. So she might seek comfort or excitement elsewhere.

The idea of subverting the expected relationships is appealing. Instead of the more common pairings, this pairing offers a fresh take. It also allows for a deeper exploration of the characters' personalities. Since they are so different, seeing them come together in a romantic way can be really interesting for fans who want to see new aspects of their favorite characters.

In some fanfictions, Ginny may reject Harry because she wants to focus on her own personal growth. She might feel that a relationship with Harry at that time would hold her back from achieving her own goals, like becoming a great Quidditch player or an accomplished witch in her own right. So, she decides to reject him to pursue her own dreams first.

One possible reason could be a growing apart due to their different career paths. Harry, being deeply involved in the wizarding world's security and Ginny having her own Quidditch career. Another reason might be the stress of living in the public eye. Their relationship may not be able to withstand the constant scrutiny and pressure from the wizarding community.

There could be a story where Ginny dumps Harry because she feels overshadowed by his fame. In this fanfiction, Ginny starts to find her own identity and realizes she can't be in a relationship where she's constantly in Harry's shadow. So she breaks up with him, and the story could then follow how Harry tries to win her back but also respects her decision.

It could also be an exploration of a dark 'what - if' scenario. Maybe the writer wants to see how the story would unfold if Ginny had a sudden and drastic change in character. Another possibility is that it's a form of creative rebellion against the typical, positive portrayal of their relationship in the original series.
