In some fanfictions, a likely plotline is Hermione getting involved in Weasley family traditions that she wasn't familiar with before. For example, she might participate in a special Weasley family celebration and bring her own unique touch to it, which could also create some interesting cultural exchanges and family bonding moments within the story.
One possible plotline could be Hermione's integration into the Weasley family in unique ways. Maybe she helps the Weasleys with their family business in a new and creative manner.
Obviously, Hermione Granger is one of the main characters. She is the central figure around whom the story revolves as she is in the situation of being 'owned by the Weasleys'.
One possible interesting plot could be Hermione adjusting to life within the Weasley family dynamic. Maybe she discovers new magical traditions or family secrets. Another could be her relationships with each of the Weasley siblings evolving in unique ways.
In some fanfictions, Hermione might get involved in a Weasley family drama. For example, helping resolve a conflict between two Weasley siblings. This could involve her using her intelligence and problem - solving skills to bring the family back together. Also, there could be a plot where Hermione starts a magical project with the Weasleys, like creating a new spell or potion, which could lead to all sorts of unexpected events and discoveries.
One interesting plotline could be when the Weasleys find out that Hermione is being targeted by a secret dark magic society. They then go to great lengths to hide her identity and keep her safe. Another could be that Hermione is falsely accused of a crime, and the Weasleys use their family's resources and connections to prove her innocence. Also, there might be a plot where Hermione discovers a powerful but dangerous magic, and the Weasleys protect her from those who want to use her for that magic.
One possible plotline could be that the Weasleys, perhaps out of over - protectiveness, start to control Hermione's study habits. They might restrict her access to the library for long hours because they think she's overworking herself. Another could be that they try to control her social life within the wizarding world, like which events she attends. It could lead to some comical situations as Hermione tries to assert her independence.
One possible plotline could be Hermione's attempts to find a cure for the werewolf curse for her werewolf friend. She might use her vast knowledge of magic to research ancient spells and potions.
I'm not sure if it's popular. It depends on various factors like how well - written it is, how unique the concept is within the large Harry Potter fanfiction community, and how much it gets promoted. There are so many fanfictions out there that it can be hard for any one to stand out.
Obviously, Hermione is one of the main characters. And then, of course, the Weasley family members would be main characters as well, like Ron, Ginny, and maybe even Mrs. Weasley who could play an important role in Hermione's new situation within the family.
One common plotline is exploring their relationship in more depth during their Hogwarts years. For example, a fanfic might focus on how they dealt with jealousy issues when Hermione was spending time with Viktor Krum. Another plotline could be set after the war, where they face new challenges as a couple, like dealing with the post - war trauma together. Some fanfics also like to imagine what would have happened if they got together earlier in the series.
One interesting plotline could be Hermione predicting major events in the wizarding world before they happen. For example, she might foresee a new dark wizard rising and start preparing the Order of the Phoenix for it. Another could be her using her seer abilities to help her friends in their personal lives, like seeing that Ron is about to make a big mistake and intervening. And sometimes, she might see visions related to the secrets of Hogwarts, leading to new adventures and discoveries within the school.
