Possible themes could revolve around self - discovery. Ginny might be on a journey of self - discovery and realizes that she has different feelings for Neville than she thought she had for Harry. It could also be about the impact of secrets. If Ginny is cheating on Harry with Neville, there would be a lot of secrets involved, and the story could show how these secrets can affect the characters and their relationships. Additionally, a theme of forgiveness might come into play, either Harry forgiving Ginny or Neville dealing with the situation in a forgiving way.
Yes, there might be some out there. However, the idea of Ginny cheating on Harry goes against the essence of their relationship in the original series. Some fanfictions might explore this concept in an interesting way, perhaps to show how relationships can be complex even in the wizarding world. But it's important to note that it's a departure from the main story's values.
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.
Another reason might be some kind of external influence, like a powerful dark magic that clouds Harry's judgment. However, this is often a stretch from the original concept of the characters. Fanfiction writers sometimes like to explore extreme scenarios to add drama to the story.
In such a fanfiction, Ginny might cheat on Harry with Dean due to a sense of being overshadowed. Harry is often the center of attention in the wizarding world, and Ginny could feel like she's always in his shadow. Dean, on the other hand, might make her feel more special and seen as an individual. Also, it could be that Ginny and Harry have had some unresolved arguments or differences that push Ginny towards Dean.
It could also be that the writer wants to explore a different side of the characters. Maybe they think there are hidden aspects of Ginny or Harry that could lead to such a situation. For example, they might imagine Ginny having some unresolved issues that could cause her to make such a mistake. However, this is a very non - traditional view of their relationship.
Well, in the 'ginny cheats on harry fanfic', a consequence might be that Ginny loses the trust of those around her. Harry might become more guarded in future relationships. Their families would also be affected. For example, the Weasley family might have to deal with the fallout and try to understand why Ginny did such a thing. And Ginny herself could end up feeling very guilty and regretful.
One possible theme could be about power dynamics. Since Neville is dominant and Harry is submissive, it might explore how power is exerted and negotiated within their relationship. For example, Neville could be guiding Harry in some magical tasks or decision - making processes in a more authoritative way.
One possible motive could be to create drama. Writers might think that by introducing such a controversial plot, they can attract more readers who are interested in seeing how the story would unfold in this unexpected direction.
One possible storyline could be that Harry is under the influence of a dark spell that makes him act out of character and be unfaithful. Another could be that he gets caught up in a dangerous mission where he has to pretend to be involved with someone else for the sake of secrecy and Ginny misinterprets it as cheating. Maybe there's a new character who manipulates Harry into thinking he has feelings for her.
A possible non - adult - themed plot could be that Ginny is trying to help Oliver with some personal issues he's having. She's being a good friend, but rumors start spreading in Hogwarts that she's cheating on Harry. Harry initially believes the rumors, but as he investigates further, he realizes that Ginny was just being kind. This leads to a story about friendship, love, and not believing everything you hear.
