One possible plotline could be that they are forced to work together on a school project despite their hatred. As they interact, they start to discover things about each other that they didn't like before but now see in a new light. Another could be that they are competing for the same thing, like a scholarship or a lead role in a play, and their hatred fuels their competitiveness. A third plotline might be that they are neighbors and keep getting into petty arguments over things like noise or property boundaries, which gradually escalates their mutual dislike.
A plotline could involve Edward being part of a group that Bella doesn't like, and vice versa. For example, Edward could be in a clique that Bella thinks is snobby, and Bella could be in a group that Edward finds too rowdy. Their hatred could be based on these group associations. Also, maybe there was an incident in the past where one of them accidentally wronged the other, like Edward accidentally ruining Bella's art project or Bella spilling something on Edward's important papers. This initial event could be the root of their hatred.
In some fanfiction, their hatred could be a result of misinformation. Maybe they heard false rumors about each other from their friends. So a plotline could be that they start to uncover the truth behind these rumors. As they do, they begin to question their hatred. Or perhaps they have different beliefs or values, such as Edward believing in a strict code of conduct and Bella being more of a free spirit. Their differences in these areas could lead to clashes and hatred, and the story could be about how they either learn to accept each other or continue to butt heads.
In some plotlines, it could be that Bella has made a deal with Peter in order to escape Edward's over - possessive nature. Peter might have his own reasons for wanting to get involved, like a long - standing feud with Edward's family. So, he uses his wits and resources to whisk Bella away to a place where Edward can't find her. This could lead to a whole new adventure for Bella as she adjusts to life away from Edward and with Peter's protection.
One possible plotline could be Bella coming from a less - privileged background and Edward, being wealthy, takes her under his wing financially. He could buy her nice things, like expensive clothes and jewelry, while they also develop a romantic relationship.
One possible plotline could be Bella initially resenting Edward as her step - dad but then gradually coming to understand him better and they form a unique bond. Another could be Edward struggling with his new role and having to deal with his own feelings for Bella in a more platonic way than in the original story.
One possible reason is that the fanfiction distorts the original relationship between Bella and Sam in a way she finds unacceptable. For instance, if it creates a false romantic tension where there shouldn't be one.
One possible plotline could be that Edward takes on a very protective role as Bella's daddy. He might be extremely strict about who she can be friends with or date, seeing as he has that over - protective daddy instinct. Another plotline could involve Edward having to deal with Bella growing up and becoming more independent, which could be a struggle for him as he's used to being in control. Maybe there could also be a plotline where Bella discovers some secrets about her past that make her question her relationship with Edward as her daddy.
One possible plotline could be them dealing with the discovery of their newfound sibling relationship. They might struggle with how it changes their previous dynamic, whether it was friendship or something more ambiguous. Another could be them protecting each other from the various threats in the 'Twilight' world as siblings, like facing off against other vampires or werewolves.
One consequence could be a broken family relationship. Their interactions would be filled with tension and animosity. Family gatherings would become uncomfortable, and other family members might be forced to take sides.
Bella's hatred could also lead to her making rash decisions. For example, she might get involved with the wrong crowd or engage in self - destructive behavior just to spite her mother. And this could further complicate the story in the fanfiction.
Another possible location could be an old, abandoned church that has been restored just for their wedding. The stained - glass windows and high ceilings would create a very solemn and beautiful atmosphere. It could also have some kind of connection to Edward's past, like it was a place his family once visited long ago.
Another reason might be Edward's overprotectiveness. He could have made a decision for Bella without consulting her first, like preventing her from seeing a friend. This kind of controlling behavior could make Bella feel frustrated and end up in tears.
