Their relationship might start off rocky. Remus is much older and has a lot of emotional baggage from his past. Hermione, on the other hand, is young and full of energy. But as they are forced to be together by the marriage law, they gradually learn to understand each other. They might start with small conversations about books and magic, and slowly build a connection.
Their relationship might develop through mutual respect. Hermione respects Fred's creativity and his ability to think outside the box, and Fred respects Hermione's intelligence and determination. This mutual respect forms the foundation for their relationship to grow, starting from a reluctant partnership due to the marriage law into a real emotional connection.
The development usually involves a lot of character growth. Ron has to grow up a bit more and become more responsible, which Hermione appreciates. Hermione, on the other hand, may learn to be more patient and less controlling. The marriage law acts as a catalyst for these changes. They might start off just trying to get through the legal requirements but end up truly caring for each other. For example, Ron might surprise Hermione with a small, thoughtful gesture, like cooking her favorite meal when she's had a tough day at work. These little things gradually build their relationship.
Remus would likely become more open. Usually so reserved about his werewolf side, with Hermione, he might start to share more. For example, he could let her in on his struggles with the wizarding world's view of him. Hermione, on the other hand, would become more empathetic. She's used to being logical, but being with Remus would make her understand emotions on a deeper level. She might also become more protective of him.
Their relationship could develop in a rather complex way. Given their very different backgrounds, there would be a lot of clashes. However, the marriage law forces them to coexist. As time passes, they might find common ground in their love for the wizarding world, albeit from different perspectives. Hermione could introduce Lucius to the idea of a more inclusive wizarding society, and Lucius could teach Hermione about the long - standing pure - blood traditions that have some value, if reformed. This mutual exchange could lead to a grudging respect and eventually something more like friendship or even love.
Their relationship could develop in a way that they become each other's support system. Given Hermione's often - alone - in - her - pursuits - type of situation and Cedric's more social but also pressured position as a popular student. They could learn from each other. For example, Cedric could teach Hermione how to relax a bit more and enjoy the simpler things in life, while Hermione could help Cedric with his studies or with any political issues he might face within the school or the wizarding world later on. And this mutual growth could lead to a deep and loving relationship.
At first, it would be very rocky. Snape is used to being alone and Hermione is used to being with her friends. But as time passes, they might start to share their interests. Hermione might show Snape some new Muggle inventions that could be useful in potions. Snape could teach Hermione some advanced potions techniques. This exchange of knowledge could lead to a mutual admiration.
Their relationship might start off rocky due to the forced nature of the marriage law. Sirius could be overprotective at first, seeing Hermione as someone he needs to shield from the dangers of his world. Hermione, on the other hand, might be frustrated by his overbearing attitude. But as time passes, they learn to communicate better and understand each other's strengths.
Perhaps Remus first notices Hermione's kindness towards him regarding his werewolf condition. She doesn't shy away but instead tries to find ways to help him. This kindness grows into something more, and they start to share their feelings. Their relationship could develop as they face challenges together, like dealing with the prejudice against werewolves. Hermione's strong will and Remus' experience combine to make them a formidable pair in the fanfiction.
In many of these fanfictions, their relationship starts off rocky. They're forced into this marriage situation, and at first, they can't stand each other. But as time goes on, they start to communicate more. Small things like sharing a meal or discussing their daily lives break the ice.
Often, it starts with the introduction of the marriage law. Then, Hermione's reaction to it is shown. It might be shock, defiance, or immediate acceptance depending on the writer's take. For example, if she's against it, she may try to find loopholes in the law.
