Fanfictions that explore Hermione's relationship with other characters in a different light are also interesting. For example, a story about her forming a strong friendship with a Slytherin student who she initially thought was an enemy. This would show a different side of her character and how she can overcome house prejudices.
One possible plot could be about Hermione getting involved in Ron's brother's business or career. For example, if it's about George, she might help him with the Weasley's Wizard Wheezes store, and during that time, a friendship or something more could develop between them.
One possible plot could be Sirius Black acting as a mentor to Hermione. He has a lot of knowledge about the wizarding world and could pass on some of his more unorthodox wisdom to her.
There could also be themes related to the wizard - Muggle divide. Mr Granger, being a Muggle, might have some unique perspectives on the wizarding world that he wants Hermione to consider. This could lead to stories where Hermione has to navigate between the two worlds, trying to bridge the gap in some way. Maybe Mr Granger wants Hermione to bring some of the positive aspects of the wizarding world back to the Muggle world, or he might be worried about how the wizarding world could change his daughter in ways he doesn't understand.
Hermione could be defiant. She's not one to be easily intimidated. She might stand her ground and demand to know what he wants, all while using her quick wits to figure out his motives. She could also try to use the situation to her advantage, like gathering information from him about the Death Eaters' plans.
They might be interested in adventure - themed fanfictions where Hermione goes on some exciting quests. For example, she could be exploring ancient magical ruins or trying to solve a mystery that even Dumbledore couldn't figure out.
A less common but still interesting trope could be the 'time - travel' trope in relation to them. For instance, if Hermione were to go back in time and meet a younger Fleur, or vice versa. This could lead to all sorts of interesting plot developments as they interact with the past or future versions of each other and the events in the wizarding world.
Some fanfictions explore the idea of Hermione being sorted into Slytherin instead of Gryffindor. This changes their relationship as they are in the same house. It can lead to them becoming friends or rivals in a different way than in the original series, and often there are complex relationships that develop between them over time.
There could also be a plot where Rodolphus is sent on a mission to spy on Hermione, but instead, he becomes fascinated by her. This leads to a complex relationship where he has to balance his loyalty to the Death Eaters and his growing feelings for Hermione. It's a really interesting exploration of conflicting loyalties and unexpected love.
One common theme is redemption. Snape, with his complex past, might find redemption through his relationship with Hermione. Another is the breaking of stereotypes. Hermione is a Muggle - born and Snape has his own prejudices which are overcome.
One of the well - received ones might be 'Dark Desires' which delves deep into the complex relationship between Voldemort and Hermione in a very interesting way. It has a unique plot that keeps you hooked from start to finish.
