It's also possible that other characters would get involved. Harry and Ron, being Hermione's closest friends, would surely notice her absence. They could come to her rescue. There might be an epic battle of magic between them and Draco, or they could try to reason with Draco, appealing to his better nature if he has one.
If Ron and Hermione leave Harry in the fanfiction, it would change the entire fabric of the story. Harry would have to reevaluate his relationships with other characters. For example, he might turn to Neville for support more often. Also, the power dynamic within the wizarding world could shift. Since Ron and Hermione were important figures in the fight against Voldemort, their absence could give the Death Eaters an advantage, or it could inspire others to step up in unexpected ways. Harry would be forced to grow in ways he hadn't before, and it would be a journey full of self - discovery and new challenges.
One possibility is that they start arguing at first. Draco, being his usual snarky self, might blame Hermione for getting them into this situation. But as time passes, they could gradually start to understand each other better. They might share some of their deepest fears and secrets, which they would never have done in normal circumstances.
She might say yes. In the fanfiction world, this could be a chance for a complete rewrite of their relationship. They could go to the Yule Ball together and shock everyone. This would cause a stir among the Gryffindors and Slytherins alike. Their friends would be confused, but it could also open the door for more inter - house unity. They could dance together and have a great time, and maybe this would be the start of a beautiful, if unexpected, relationship.
Hermione could leave Draco if she realizes that they have fundamental differences in values. For example, if Draco still holds some pure - blood supremacist views, Hermione, being a Muggle - born advocate, would not be able to tolerate it in the long run.
In a fanfiction scenario where Hermione is sold to Draco, it could be a very dark and angsty story. Draco might use Hermione as a means to gain power or status within the wizarding world. Hermione, on the other hand, would surely fight against this situation. She would try to find a way to escape and expose Draco's actions. It could also lead to a complex exploration of power dynamics and morality in the wizarding society.
Another idea is that Draco becomes involved in some sort of underground magical movement. After Azkaban, he may be disillusioned with the established magical order. He could join a group that aims to reform or even overthrow the current power structures in the wizarding world, leading to all sorts of adventures and conflicts.
Maybe there's some sort of plot or secret that he doesn't want Hermione to expose. He might think that by keeping her close, he can prevent her from telling others. For example, if he's involved in some sort of illegal or unethical magic practice and he believes Hermione has figured it out.
It could start with an accidental encounter in a less - traveled part of Hogwarts. Maybe they both discover a hidden room or a secret passage. In that moment of shared discovery, they put aside their differences. As they start to explore the mystery together, they begin to understand and appreciate each other. Hermione might find Draco's sense of adventure (once he steps out of his pure - blood supremacist mindset) appealing, and Draco could be impressed by Hermione's vast knowledge.
In a Draco and Hermione reunion fanfiction, they might initially be hesitant. Draco could be ashamed of his past actions during the wizarding war. Hermione, on the other hand, might be curious yet guarded. Maybe they meet in Diagon Alley by chance. Draco could be there to buy some rare potions ingredients for his new business venture. Hermione is browsing the new books at Flourish and Blotts. Their eyes meet, and there's a moment of shock. Draco, trying to be polite, nods. Hermione, after a brief hesitation, nods back. And that could be the start of a series of unexpected interactions.
A lot could happen. For starters, Hermione would likely try to find ways to blend in while also exploring the new place. She might befriend some locals and share her knowledge in a very discreet way. Draco would probably struggle more with the idea of living among Muggles. He might be a bit of a loner at first. But as time goes on, they could both get involved in the local community in different ways. Maybe they start a small business together, using Hermione's smarts and Draco's charm (in his own way).
