One common theme is redemption. Draco often has to atone for his past actions and Hermione helps him in that journey within the context of their marriage. Another theme is the breaking of social barriers, as their union goes against the traditional pure - blood/muggle - born divide in the wizarding world. Also, love conquering differences is a big theme, showing that despite their initial differences in beliefs and backgrounds, they can have a loving marriage.
A fanfic might explore how Tonks' Metamorphmagus ability plays a role in their relationship. Maybe she changes her appearance to surprise Harry and Hermione on special occasions. The three of them might have to face some opposition from the more traditional wizarding families, but they stand strong. Their marriage could be a symbol of a new, more inclusive era in the wizarding world. They would travel together, sharing their knowledge of different magical cultures, and write books about their adventures.
Love against all odds is also a significant theme. Given their past animosity and the differences in their backgrounds, their relationship in these fanfics is often about how they can find love in the most unlikely of situations. It's about looking past the surface and seeing the person beneath, like Hermione seeing the good in Draco despite his past actions.
One popular 'Draco and Hermione married fanfic' is 'The Ties That Bind'. It has an interesting plot where they are forced to work together due to a magical pact. Another is 'Bound by Destiny' which shows their relationship evolving gradually in a post - war wizarding world. And 'A Different Kind of Love' gives a unique take on their married life with lots of character development.
Maybe Voldemort's remaining followers. Even though Voldemort is gone, there could be some die - hard Death Eaters who are still bitter about the fall of their dark lord. They see Harry as the main reason for their downfall and Hermione as an easy target because of her Muggle - born status. So they plot against the newly - married couple, perhaps trying to hex them or steal their magic.
One popular 'hermione married draco fanfic' is 'The Green Girl' which has an interesting take on their relationship. It shows how they overcome the initial differences and prejudices from their Hogwarts days.
It could be Oliver Wood. He was passionate about Quidditch and a great player. In the fanfic, his love for the sport might attract Hermione, and they could have a relationship based on mutual respect and his exciting Quidditch - filled life.
They could start a magical school of their own. As a married couple, they would pool their resources and knowledge. Hermione's love for learning and Harry's practical experience would make for a great curriculum. They would face opposition from the traditional wizarding schools at first, but eventually prove that their new way of teaching magic is beneficial for young wizards and witches.
Well, their life would probably be full of excitement. If the Quidditch player was often away for games, Hermione would have to get used to his absences. But when he was home, they'd likely have a great time sharing stories of his Quidditch adventures. They might also have a big social circle within the Quidditch community.
One common theme is the exploration of a non - traditional relationship. Since it's not part of the original canon, it allows authors to break boundaries and create unique relationship dynamics.
