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.
Well, in fanfiction, anything can happen. Maybe a writer decides to explore a different side of their relationship. It could be due to a misunderstanding that spirals out of control. For example, Edward might misinterpret Bella's actions as being self - centered or manipulative, and Bella could see Edward as overbearing and controlling. This would completely change the dynamic from the original love - story in Twilight.
A common plot could be revenge. If they start hating each other, one or both of them might seek revenge. For instance, Bella could try to expose Edward's vampire secrets to the human world as a way to get back at him. Another plot is competition. They could be competing for something, like a powerful vampire artifact or the love of another character, which makes them rivals and fills them with hatred.
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.
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 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.
Another plotline could be centered around Sasuke's ninja duties. He might be constantly away on dangerous missions, and when he's home, he's so preoccupied with the safety of the village and potential threats that he neglects Sakura's emotional needs. This could lead to a situation where Sakura feels unloved and Sasuke seems to 'hate' their married situation because he can't balance his two worlds well.
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.
Some fanfictions might have a plotline where Bella and Edward face challenges related to their new married life during the honeymoon. For instance, they have to figure out how to balance their different needs. Edward, being a vampire, has different sleeping patterns and dietary requirements. Bella, on the other hand, is still adjusting to her new life as a vampire's wife. This creates some interesting situations and conflicts that they need to resolve together.
One possible plotline could be that Edward returns after a long absence and finds Bella has changed in unexpected ways. Maybe she has developed new powers or a stronger sense of self. Another could be that they reunite in a dangerous situation, like facing a new vampire threat together, which forces them to re - evaluate their relationship.
