Well, it could be that the fanfiction is trying to show Ginny's jealousy or resentment in a new light. Perhaps she's jealous of Harry's fame or the attention he gets. Or maybe the writer is simply exploring a 'what if' scenario where Ginny and Harry's relationship took a different turn from the start. In the original story, they end up together, but fanfiction allows for alternative storylines, and this could be one of them where Ginny hates Harry for various reasons that might be related to their different personalities, goals or the pressure of the wizarding world around them.
One possible reason could be a creative twist by the author to explore different relationship dynamics. Maybe they want to create conflict and drama. For example, the author might make Harry misunderstand Ginny's actions or intentions, leading to this false sense of hatred in the fan - made story.
It could be that the fanfiction writer wants to create some sort of conflict. By having Harry's kids hate Ginny, it adds a new layer of drama to the story. They might be made to believe false things about Ginny which lead to their hatred.
One reason could be a divergence from the original friendship dynamic in the books. In the canon, Harry and Ron are good friends, and fanfiction that shows Harry hating Ron might go against what many fans consider the essence of their relationship.
One possible reason could be miscommunication. Maybe Ginny did something without fully explaining her intentions to Harry, and in the heat of the moment, he yells. For example, if she made a decision about their relationship without consulting him first.
One possible reason could be jealousy. Maybe Ginny sees Harry getting too friendly with another female character in the fanfiction world. Another reason might be differences in their future plans. For example, Harry may be too focused on his Auror duties and Ginny wants more family time.
One possible reason could be miscommunication. Maybe Harry made a decision without consulting Ginny, like joining a dangerous mission. In fanfiction, authors often play with the idea of misunderstandings to create drama. For example, Harry might have thought he was protecting Ginny, but she saw it as him not trusting her enough.
One possible reason could be that the 'light' in the fanfiction represents something he associates with strict rules or a false sense of goodness. Maybe it has been used to manipulate people, and Harry, being perceptive, sees through it and thus hates it.
One possible reason could be that his family in the fanfiction might be cruel or neglectful towards him. Maybe they constantly put him down or don't support his dreams and ambitions, which would lead to his hatred.
One possible reason could be a divergence in the characters' personalities as portrayed in the fanfiction. Maybe the writer made Molly have traits that Harry would realistically dislike. For example, if Molly was written as overly controlling or mean-spirited towards Harry in the fanfic.
Well, it could be that the two come from very different fictional universes with distinct magic systems and cultures. Harry Potter's world is based on a more European wizarding society, while Odin is from Norse mythology. Their values and the way magic works might clash in the mind of the fanfiction writer, leading to this 'hate' concept.
