Often, it develops as they face external threats. Enemies from other vampire covens may target Bella because of her connection to Edward. As they fight off these threats side by side, their love and trust for each other grow. In many fanfictions, there are also emotional challenges. For instance, if Bella starts to feel suffocated by Edward's over - protection, they have to work through their issues, which ultimately strengthens their relationship.
In some stories, their relationship deepens when they explore the human side of their love. Despite being vampires, they might engage in human - like activities such as going to a high school dance again (even if it's a vampire - only event). This re - connection with their human pasts and the emotions associated with it, like nostalgia and the joy of simple things, enriches their relationship in the fanfiction.
It often starts with attraction. Edward is drawn to Bella's unique scent and her differentness. Bella, on the other hand, is intrigued by Edward's mysterious nature.
Their relationship develops as Edward imparts his knowledge to Bella. Since he's her master, he has a certain authority. But as time passes, Bella might start to question some of his decisions, which adds tension and also deepens their relationship as they work through these issues.
Their relationship might develop through shared experiences. For example, they could go on adventures together in the human world that Bella has never fully explored. These experiences bring them closer as they learn more about each other.
Bella's character might become more confident. Without Edward, she has to rely on herself, which forces her to grow. As a vampire, she'll be more physically capable, and this could translate into mental strength as well.
At first, it might be a bit rocky. Since the marriage is by treaty, they may be a bit wary of each other. But as they start spending time together, they could begin to discover common interests. For instance, they might both be interested in a particular type of literature or music, which helps to break the ice.
Fanfiction expands their relationship by exploring different scenarios. For instance, they could face a new enemy together, which would strengthen their bond as they protect each other.
At first, Bella may be resistant to Edward's claim. She's likely a normal girl thrust into this dangerous mob world. But as Edward shows his protective side and she gets to know the real him behind the mob boss facade, their relationship blossoms. Edward may use his power to court her in a unique way, like taking her to exclusive and dangerous places that only he can access. This builds a sense of adventure and closeness between them.
The relationship develops in a rather complex way. Since Edward pays Bella to marry him, there's an initial power imbalance. However, as they live together, they start to understand each other better. For example, Edward might learn about Bella's dreams and fears, and Bella might come to understand Edward's reasons for his actions in the vampire world. This leads to a deeper emotional bond that goes beyond the initial transaction.
In a human fanfiction, their relationship might start with mutual suspicion. Since they are from different supernatural groups, they may not trust each other at first. But as they face common challenges in the human world, like dealing with human hunters who target supernatural beings, they start to rely on each other. This could gradually turn into respect and then, perhaps, love.
It redefines it by making it unequal. Bella is in a position of being 'owned' in a sense, which is a huge change from their normal relationship where they are more like equals in love.
