Well, it offers a different take on the original story. People like to see how the characters can develop in new situations. When Edward rejects Bella, it's a big change from the norm in the Twilight series.
Well, some writers might want to explore a different side of Bella's character. By having her reject Edward, they can show her as a more assertive and independent figure, not just defined by her relationship with him.
One possible story could be where Bella rejects Edward because she discovers a side of him that is too overprotective in a way that suffocates her independence. She might realize that she wants to explore the world on her own terms without his constant interference.
There are fanfictions where Edward rejects Bella for a different reason than in the original story. For example, he might think that being with her will put her in more danger from other vampires or supernatural beings. This then leads Bella to go on a journey of self - discovery, often traveling to different places to learn about the world of the supernatural from a different perspective.
One possible reason could be that Edward has some internal conflict. Maybe he has a strong sense of self - control and believes that getting involved with Bella in that way goes against his principles. He might be worried about the consequences it could have on Bella's life or his own existence as a vampire.
I'm not entirely sure specifically about a 'bella rejects imprint fanfiction' without reading it. But generally, in Twilight - related fanfiction, 'imprint' is a concept. If Bella rejects it, it might be a story where she goes against the traditional or fated 'imprint' connection, perhaps to assert her own free will or because she has other romantic interests outside of that pre - ordained bond.
One reason could be jealousy. Rosalie might be jealous of Bella's relationship with Edward. In the 'Twilight' universe, Rosalie has her own insecurities and desires, and Bella's presence disrupts the dynamic she's used to. Another reason could be that Rosalie sees Bella as a threat to the vampire coven's secrecy. Bella's human clumsiness and her connection to the vampires could draw unwanted attention.
One possible reason could be the difference in their species. Edward is a vampire and Jacob is a werewolf, and in the fanfiction, Edward might reject Jacob due to the long - standing enmity between their kinds. Vampires and werewolves are often portrayed as natural enemies, so this could be a significant factor.
Bella's seduction can create a lot of tension. It makes the relationship between her and Edward more complex. Since Edward rejects her, it leads to a kind of emotional turmoil for Bella. This can drive the plot forward as Bella might then try different ways to win Edward over or she might have to face her own feelings of rejection and grow from it.
In the 'bella is edward's pet fanfiction', the relationship is a creative and often controversial take. It could be that the author is exploring themes of dependency and power. Bella as a pet might symbolize her vulnerability and Edward's strength. However, this also raises questions about her agency. Does she have any say in things? Or is she completely at Edward's mercy? It can be a very complex relationship to unpack within the framework of the fanfiction.
