The 'alternate universe' trope is also common. In some fanfictions, the story might be set in a world where the normal rules of the Harry Potter universe don't apply. For example, there could be a world where age differences don't matter as much, or where Remus and Hermione are brought together in a different context, like they are on a secret mission together and their relationship blossoms during that time. There are also stories that might involve time - travel, where Hermione goes back in time and meets a younger Remus, which adds another layer of complexity to their relationship.
In some fanfictions, Remus Lupin might be hard for Hermione because of their age difference. Lupin is much older, and this can create complex power dynamics and social taboos in the relationship. Also, their personalities are quite different. Hermione is highly studious and often by - the - book, while Lupin has a more laid - back and world - weary nature, which could lead to clashes and difficulties in their interactions.
Another theme is the exploration of the werewolf aspect of Lupin. Fanfictions might show how Hermione reacts to Lupin's lycanthropy and how she might try to find ways to help him or understand it on a deeper level. For example, she could be researching ways to ease his transformations.
