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.
In fanfiction, their argument could stem from Harry's overprotectiveness. Ginny is a strong witch, but Harry might be constantly trying to keep her out of dangerous situations, which Ginny could see as him not believing in her abilities. Additionally, they could argue over how to raise their children, if the fanfiction has them in that stage of life. Harry might have more traditional views while Ginny could be more progressive, leading to disagreements.
One possible reason could be differences in their approach to fighting Voldemort. Sirius might be more reckless and Harry, having faced more direct threats, could be more cautious. Another reason could be Sirius' over - protectiveness of Harry. He might try to stop Harry from taking certain risks, which Harry sees as necessary for his growth and the defeat of the Dark Lord.
It could also be due to misunderstandings. Fanfiction often plays with the idea of miscommunication between them. Maybe Bella misinterprets Edward's over - protectiveness as a lack of trust in her ability to handle vampire - related situations. Or Edward might misunderstand Bella's need for independence as a sign that she doesn't love him as much as he thought. These misunderstandings can escalate into arguments.

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 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 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.

In the fanfiction world, it could also be about their personal feelings. Jacob is still hung up on Bella for a long time, and Leah might see this as a weakness or something that is getting in the way of the pack's progress. Also, Leah has her own emotional baggage, and Jacob's actions might trigger some of her insecurities, thus leading to an argument.
One possible reason could be differences in their ninja duties. Naruto is often away on dangerous missions, and Hinata might be worried and want him to take fewer risks. This could lead to an argument as Naruto is dedicated to protecting the village at all costs.
