In a Hogwarts setting, Bella and Edward's relationship might develop through shared classes. For example, in Potions class, Bella might struggle and Edward, with his extensive knowledge of magical ingredients (from his long life), helps her out. This leads to them spending more time together outside of class, perhaps in the Gryffindor common room (if Bella is in Gryffindor) or in a secret corner of the Hogwarts library. As they get closer, they start to share their deepest secrets, with Edward revealing his vampire identity to Bella, and Bella sharing her dreams and fears about the wizarding world. Their relationship then becomes a source of strength for them as they face the challenges of Hogwarts life together.
At first, Edward could be seen as a bit of an enigma to Bella in Hogwarts. He always seems to be lurking in the shadows. But as Bella participates in Quidditch (maybe as a Chaser) and Edward watches her from the stands, he starts to develop a fascination for her. Bella, on the other hand, notices Edward's strange behavior and becomes determined to figure him out. They start to communicate through notes passed in the corridors. This simple form of communication evolves into deeper conversations. As they learn more about each other, they find that they have a lot in common despite their different natures, and their relationship blossoms into a deep and meaningful connection within the walls of Hogwarts.
Their relationship could start off rocky. Edward might be standoffish at first because he's worried about his vampire nature being discovered in the wizarding world. But Bella's kindness and her own inquisitive nature gradually draw him in. They could start with small exchanges in the library, where they both like to study, and then slowly progress to going on walks around the Hogwarts grounds. Eventually, they might face a big crisis together, like an attack by a dark wizard, which makes them realize their feelings for each other are deeper than they thought.
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 might develop slowly. They could start as friends, getting to know each other better over coffee breaks between classes.
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 could develop quickly. After meeting at the club, they might exchange phone numbers or some other means of contact. Then they would start to meet more often, like going for walks in the park or having coffee together. Their conversations would deepen, and they would learn more about each other's personalities and pasts.
Their relationship would likely become more intense. They would have a new bond through the baby. Edward would be even more protective of Bella, not just because he loves her, but also because she's carrying their child.
Their relationship often deepens. With the idea of having a baby, they become more connected on an even deeper emotional level. They start to see each other in new roles, as future parents.
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.
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.
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.
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.
