Well, a plot twist might be that the Marriage Law is actually part of a dark wizard's plan. Hermione and Charlie then find themselves in the middle of a much larger conspiracy. They might have to use their unique skills - Hermione's intelligence and Charlie's dragon - handling knowledge - to expose the plot and in the process, their relationship could either strengthen or face challenges. Also, perhaps there are ancient magic rules related to such marriages that they need to figure out.
Hermione would likely become more assertive in her relationship with Charlie. She's used to being in charge of her own life, and now she has to make decisions with someone else. Charlie, on the other hand, might become more open and communicative. He's used to being around dragons, not people all the time. Their relationship would force him to be more social.
One possible fanfiction could be where the Marriage Law forces Hermione to consider Charlie as a potential partner. Maybe they start off as reluctant allies, but as they get to know each other through the arranged situation, they discover shared interests in magical creatures. Hermione's intelligence and Charlie's hands - on experience with dragons create a unique dynamic.
The Ministry of Magic officials who strictly enforce the marriage law could be antagonists. They might be so bent on following the rules that they don't consider the individual feelings of Charlie and Hermione. For example, an overzealous bureaucrat who keeps checking on them to make sure they are fulfilling their marital duties according to the law.
One idea could be that they initially resist the marriage law due to their different worlds in Hogwarts. Charlie is all about dragons and Hermione is focused on academics. But as they start to spend time together, they discover they share a love for magical creatures in a different way. Hermione starts to see the beauty in Charlie's wild dragon - taming ways, and Charlie is amazed by Hermione's vast knowledge which could be useful in dragon conservation.
One great fanfic could be 'The Unforeseen Bond'. It explores how Hermione and Draco are forced to deal with the new marriage law. The story does an amazing job of showing their initial animosity gradually turn into something more. It has well - written dialogue that stays true to their characters from the original series.
Hermione and Harry are the central figures. However, other characters like Ron also get affected. Ron's relationship with Hermione and Harry is put to the test because of this law. He might feel jealous or left behind. Also, characters like Dumbledore or Snape (if the fanfic includes them in this context) could play roles in either supporting or opposing the law which in turn affects Hermione and Harry.
Perhaps in the fanfiction, Hermione is initially very angry about being paired with Charlie under the Marriage Law. But Charlie takes her to his dragon reserve. There, Hermione sees a different side of Charlie and his passion for magical creatures. This experience makes her more open - minded towards him. Meanwhile, Charlie starts to admire Hermione's intelligence and her determination to fight for what she believes in. Their relationship slowly evolves from forced to something they both cherish.
Character development is key. A good fanfic should show how Hermione and Draco grow and change because of the marriage law. For example, they might start to see the good in each other that they never noticed before.
Well, in a fanfic about Hermione and Snape under a marriage law, it could be a story full of drama. Maybe the marriage law forces them together for some political or magical stability reason. Hermione, with her intelligence and strong will, might initially resist. Snape, on the other hand, would be his usual brooding self. But over time, they could start to understand each other better, like Hermione seeing Snape's hidden kindness and Snape respecting Hermione's capabilities.
