Hermione would face a great deal of prejudice from the pure - blood society. Since she is Muggle - born, many in the wizarding world, especially those in the Malfoy's social circle, would look down on her. She would also have to deal with Draco's own internalized prejudices. He has been taught to think of Muggle - borns as inferior, and Hermione would have to work hard to change his view. Another challenge would be maintaining her own identity. The Malfoy family has certain expectations and a way of life, and Hermione would have to find a way to be true to herself while also fitting into this new family dynamic.
If Lucius wants Draco to marry Hermione, it could lead to a lot of political implications within the wizarding world. The Malfoys are a powerful pure - blood family, and Hermione's friendship with Harry Potter and association with Dumbledore's side could be seen as a way for Lucius to gain some sort of advantage. For Draco, this could be a way out of the dark path he was on in the original story. He could become more of an ally to Hermione and her friends. And Hermione might find herself in a very strange position of having to balance her own values with the expectations of the Malfoy family.
One popular example could be 'A Chance at Redemption' where Draco realizes his true feelings for Hermione over time. It shows their relationship evolving from animosity to love in a well - paced story.
Well, in many of these fanfictions, at first there's usually a lot of tension. Draco and Hermione come from different backgrounds and have had past rivalries. But then, something changes. Maybe they're paired up for a project or they have to work together to solve a mystery. As they spend time together, they start to see each other's good qualities. Draco might see Hermione's intelligence and kindness, and Hermione might see Draco's hidden depths. This mutual discovery leads to feelings of attraction and eventually Draco's desire to marry Hermione.
One way this could develop is that Voldemort sees an opportunity to use Hermione's intelligence for his own gain through this union. He might think that by having Draco marry Hermione, he can control the magical knowledge she has. Draco, on the other hand, might initially resist as he has his own pure - blood ideals. But under Voldemort's pressure, he could be forced into it. Hermione would surely fight against it, using her wits and the support of her friends like Harry and Ron to find a way out of this strange and unwanted situation.
In many fanfictions exploring this so - called love triangle, it often goes against the traditional character alignments in the original 'Harry Potter' series. Draco and Hermione have a complex relationship in these stories. Draco is usually depicted as having a change of heart from his pure - blood supremacist views. Hermione, on the other hand, might be attracted to this new side of Draco. As for Lucius, his presence in the love triangle adds a layer of complication. He is an older, more established figure in the wizarding world, and his relationship with Draco further muddles the dynamics. However, it's important to note that these are all fan - created ideas that deviate from the canon story.
Perhaps there's a plot where Lucius Malfoy is in a situation where he owes Hermione a debt. This could lead to a strange relationship where he has to follow her around and protect her. As time passes, he starts to develop unexpected feelings for her.
You can try searching on fanfiction websites such as Archive of Our Own (AO3). It has a vast collection of fanfictions from various fandoms, and there's a good chance you'll find some stories related to Lucius and Hermione there.
There are also some fanfictions that explore an alternate universe where Lucius and Hermione meet under different circumstances, like in a magical school where there are no Voldemort - related threats. In these stories, their relationship can develop in a more positive and less dark way, and you can often find them by looking for AU (alternate universe) tags on fanfiction platforms.
The Death Eaters would probably be divided. Some might see it as a great opportunity to gain more power through this union, while others might be suspicious of Hermione and worry that she will be a threat to their cause. The students at Hogwarts would be in an uproar. Hermione's friends would be ready to fight for her freedom. Ginny, for example, would be a strong advocate for Hermione. And Neville, who has grown so much in courage, would also stand up against this wrong - doing. There would be a lot of tension and drama within the wizarding community as a whole.
