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.
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.
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.
In some 'Harry and Hermione get married fanfic', they might have to deal with a new dark threat that emerges right after their wedding. This threat could be related to a long - lost dark magic artifact that the villains want to use to take over the wizarding world. Harry and Hermione, being the intelligent and powerful couple they are, use their wits and magic to fight against this new evil. They might even get help from some unexpected allies from different houses in Hogwarts.
In the original series, their friendship was built on a foundation of trust and common goals, like fighting Voldemort. In a married fanfic, that trust would be even deeper. They would be more involved in each other's daily lives. For instance, Hermione might be more involved in Harry's Auror work, giving him advice on how to handle certain magical cases. And Harry would be more involved in Hermione's efforts in the Ministry of Magic for the betterment of the wizarding world. Their relationship would be a blend of love, friendship, and partnership, which is different from just the friendship they had before.
One reason is that it offers a different take on the relationships in the Harry Potter series. Fans are always curious about alternative storylines. Harry and Hermione have a strong friendship in the original series, so seeing it develop into a romantic relationship and marriage in fanfictions is appealing.
Well, it gives writers a chance to create new and exciting storylines. In the original books, their relationship is platonic. But by making them married in a fanfiction, new plot possibilities open up. For instance, they could face unique challenges together like dealing with Hogwarts rules as a married couple or having a combined influence on the other students.
Well, Harry might support Hermione in her career pursuits at the Ministry. He could use his fame and influence to help her get the resources she needs for her projects. For example, if she's trying to start a new magical education program, Harry would be there to back her up. Hermione would support Harry in his work with the Aurors. She'd give him advice on how to handle difficult magical creatures or dark wizards, based on her vast knowledge of magic.
In fanfic, their daily routines might include waking up early. Harry could be making them a simple breakfast while Hermione reads the morning paper. They would likely discuss magical research Hermione is doing or the state of the wizarding world. In the evenings, they might sit by the fireplace and share stories of their Hogwarts days.
It could be a spell gone wrong. Maybe some dark magic or a misfired charm affected her memory. It's not uncommon in the wizarding world for things like this to happen.
