One interesting fanfiction could be about Lucius Malfoy having a change of heart and secretly helping Harry Potter in a dangerous situation.

Another plotline might involve a magical accident that causes Hermione to have a change in personality. This new, bolder Hermione starts flirting with Lucius out of curiosity and to see how the pure - blooded wizard will react. It could lead to some tense and interesting interactions between them.
Perhaps in a post - war scenario, Hermione is working on reforming the wizarding laws. Lucius, who has lost much of his power and status, is begrudgingly involved in the process. Through a series of debates and interactions, they develop an unexpected connection that challenges their long - held beliefs about each other.
In some fanfictions, Draco Malfoy might be involved too. As Lucius Malfoy's son, he could interact with his aunt in various ways.

Or perhaps he could be suspicious of her actions if she starts to go against the family's traditional values.

One common theme is family loyalty. In a lot of fanfictions, we see Draco and Lucius sticking together through thick and thin, no matter what the situation is in the wizarding world.
