Perhaps Edward's loyalty to Bella plays a part. In the Twilight universe, Edward is deeply in love with Bella. In this fanfiction, he may reject Jacob because his heart is already set on Bella and he doesn't want to risk his relationship with her by getting involved with Jacob in any way.
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.
It could also be a matter of personal values. Edward has his own set of moral and ethical beliefs that are shaped by his long existence as a vampire. Jacob, being a werewolf, may have different values. Edward might find that these differences are too great and thus reject Jacob.
In some fanfictions, Jacob may reject his imprint because he has a different vision for his future. He might have dreams and goals that he believes will be hindered by the imprint. For instance, if he wants to explore the world or pursue a certain career path that he thinks the imprint will prevent. Additionally, he could be in denial about the imprint because it goes against his idea of 'true love' and he is waiting for a more 'natural' form of love to develop.
One possible reason could be their rivalry over a love interest, like Bella. Jacob loves Bella and Edward is in a relationship with her. This love triangle often leads to tension and could easily erupt into a fight.
It could also be that Jacob has his own ideals and values when it comes to love. He has this image of being with Bella in his mind, and the imprint doesn't fit into that. He might feel that his feelings for Bella are pure and true, while the imprint seems like a more primal or instinctual thing that he doesn't want to succumb to. So, in order to stay true to his own sense of self and his feelings for Bella, he rejects the imprint.
One reason could be Jacob's more down - to - earth nature. He represents a more normal, warm - hearted life compared to Edward's rather cold and sometimes brooding vampire existence. Bella might be drawn to the simplicity and closeness to nature that Jacob offers.
One possible reason could be that Sasuke is too focused on his revenge. His single - minded pursuit of power and vengeance against Itachi leaves little room for romantic feelings. He might see a relationship with Sakura as a distraction from his goals.
One possible reason could be that Naruto has a different love interest in his heart, like Hinata. In the original story, his relationship with Sakura was more of a friendship - like bond. Another reason might be for the sake of creating an unexpected plot twist in the fanfiction. Maybe the writer wants to explore different emotional and relationship dynamics that don't follow the typical Naruto - Sakura pairing.
One reason could be that Naruto might be too focused on his ninja goals. He has always been determined to become Hokage and might see a relationship as a distraction. In fanfiction, his single - minded pursuit of his dream could lead him to reject Hinata.
One possible reason could be Anakin's increasing fall to the dark side. Padme is a strong believer in the Jedi ideals and the light side, so she might reject Anakin as she sees him slipping away from what she values. Another reason could be Anakin's possessive and controlling nature. Padme is an independent woman, and his overbearing behavior could be a turn - off.
In the 'harry rejects draco fanfiction', it could be due to the social divide between Gryffindor and Slytherin. Harry, as a Gryffindor, has been taught to distrust Slytherins. Draco's actions towards Harry's friends, like Hermione who is a Muggle - born, also contribute. Harry may reject Draco because he stands for the discrimination that Hermione has faced from Draco and his family.
In the 'naruto rejects kushina fanfiction', it could be due to a sense of self - discovery for Naruto. He may be on a journey to find his true identity and purpose, and he believes that Kushina somehow stands in the way of that. Maybe he has new friends or allies in the fanfiction that he values more and their ideals are contrary to Kushina's. So, to stay true to these new relationships and his own evolving self, he rejects Kushina.
