In some Dramione fanfictions, Ron might break up with Hermione because he feels overshadowed by her intelligence. He could be tired of always being in her shadow and decides to end the relationship. This then paves the way for a potential Dramione relationship as Hermione and Draco start to interact more.
In the fanfiction, perhaps there are trust issues. Ron has a bit of a jealous streak. If he wrongly accuses Hermione of being too friendly with other male characters, like Harry or some new acquaintance, it could create a rift. This constant suspicion would wear Hermione down, and she might decide she's had enough.
Well, for Hermione, it would be a huge emotional blow. She might become more withdrawn at first, focusing on her studies even more to cope. Draco, on the other hand, might see this as an opportunity. Since it's a Dramione fanfic, he could start to approach Hermione more gently, trying to offer her support and gradually winning her over.
One possible reason could be their different career paths. Harry might be more focused on Auror work which is dangerous, and Hermione, being the practical person she is, may not want to live in constant fear for his safety. Another reason could be a growing apart in their values. Maybe as they get older, Hermione realizes that Harry has a more impulsive nature when it comes to making decisions regarding the wizarding world's politics, while she prefers a more calculated approach.
Maybe it's because of their different outlooks on life in the wizarding world. Hermione is very much about following the rules and using magic for good and knowledge, while Draco has been more influenced by the power - hungry and sometimes underhanded ways of his family. This could lead to constant arguments and ultimately a break - up.
It could be due to a misunderstanding. Ron might misinterpret Hermione's relationship with Draco. He could think there's something going on between them, especially in fanfiction where the Dramione pairing is the end goal. So, in his jealousy or anger, he decides to leave Hermione while she's pregnant without really understanding the situation.
One possible reason could be that their different career paths put a strain on their relationship. Ron might be more focused on his Auror work, often away on dangerous missions, while Hermione is deeply involved in the Ministry's research and reform projects. The long hours and high - stress of their jobs could lead to less time for each other and growing apart.
Perhaps their personalities are just too different in the fanfic. Naruto is often depicted as impulsive and reckless, while Ino can be more calculating and controlled. These differences could lead to constant clashes. For instance, when making decisions about their future together, they might not be able to see eye - to - eye. Naruto might want to continue taking on dangerous missions, while Ino may prefer a more stable and quiet life.
In the fanfic, it could be that Bulma has fallen out of love with Vegeta. Maybe she has met someone else who seems more compatible with her. This new person could be more in tune with her technological interests or simply be more emotionally available. Or it could be that an event has occurred that has made Bulma see Vegeta in a different, less favorable light. For instance, if Vegeta made a decision during a battle that put their family at risk without consulting her, it could be a breaking point.
A possible reason could be jealousy. Maybe Hermione becomes jealous of Harry's fame and the attention he always gets. She might feel overshadowed and decide to break away from him to find her own identity outside of his shadow.
One possible reason could be miscommunication. Maybe Hinata felt that Naruto was always so focused on his ninja duties and didn't have enough time for her. Another reason might be external pressure. For example, if there were some political or family issues in the Hidden Leaf Village that made their relationship difficult to maintain. It could also be that Hinata's own insecurities got the best of her. She might have felt that she wasn't good enough for Naruto, who was a hero in the village.
