One idea could be exploring how they handle their kids' magical education. Maybe one of their children has a special ability that requires unique teaching methods. Another could be a story about a family vacation where they visit a new and mysterious magical place and encounter various adventures. Or perhaps a plot where they have to deal with an old enemy from their Hogwarts days who resurfaces and targets their family.
A great plot could be centered around the Weasley family's Christmas traditions. Ron and Hermione could be passing down the Weasley family's unique yuletide customs to their children while also incorporating Hermione's muggle - born knowledge. For example, they could introduce things like Christmas crackers in a magical way. Also, there could be a sub - plot where their children are trying to figure out the perfect gift for their parents, leading to some heartwarming and humorous moments.
Perhaps in the fanfiction, Ron's jealousy gets the better of him. He might be jealous of Hermione's success or her friendships with other characters like Harry or some of her academic peers. His jealousy could manifest in ways that make Hermione feel suffocated or unappreciated, causing her to end the relationship. Also, Ron may have some habits that Hermione can't tolerate anymore. For example, his slacking off on certain responsibilities or not taking things as seriously as she does.
One plot idea could be that Draco and Ron are forced to work together on a school project. They start off hating each other but gradually come to understand and respect one another as they see each other's strengths and insecurities. Another idea is a time - travel fanfic where they go back in time and have to change an event at Hogwarts that affects both their families. A third plot could be that they both get lost in the Forbidden Forest together and have to rely on each other to survive, which leads to a new - found friendship.
One idea could be a story where Hermione teams up with the Weasley brothers for a magical experiment that goes awry. Maybe they accidentally create a new type of magic that has unexpected consequences for the wizarding world. Another plot could involve Hermione getting caught in the middle of a prank war between the Weasley brothers and having to use her intelligence to either stop it or turn it into something positive. Or perhaps a plot where they all go on a secret mission together to uncover a mystery related to their families' pasts.
One plot idea could be that Hermione and Bill team up for a dangerous magical research project. They might have to travel to far - off and dangerous places, facing ancient magical creatures and dark magic along the way. Their different areas of expertise - Hermione's vast book knowledge and Bill's hands - on experience with dangerous magical situations - would make for an exciting combination.
Another plot could involve Percy being assigned to work with Hermione on a top - secret project at Hogwarts. Maybe it has something to do with protecting ancient magic texts. Along the way, they learn to respect each other's different approaches and form an unlikely friendship.
One idea could be a time - travel plot where Hermione somehow gets sent back in time and meets a younger Arthur Weasley. They could team up to solve a mystery that is related to the Weasley family's past and the wizarding world at large. This would allow for a lot of exploration of the wizarding world's history and the early days of the Weasley family.
A really interesting plot could be that right before the wedding, a dark wizard from Ron's past tries to disrupt it. Hermione and Ron, along with their friends, have to fight off the threat while still making sure the wedding goes on as planned. It would add a lot of action and adventure to the fanfiction.
Maybe a fanfiction where Percy and his family get magically transported to a different era. They have to rely on each other and their family bonds to find a way back. Percy, being the rule - follower, might struggle at first with the lack of established rules in this new situation, but then he realizes the importance of his family's more flexible ways.
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.
A possible plot is that Ron - turned - girl gets involved in a magical beauty pageant that has some dark secrets behind it. She enters it thinking it's just a bit of fun but soon realizes there's more at stake. This could lead to her using her typical Ron - like courage and quick thinking to expose the secrets. Additionally, her romantic interests might shift. Instead of pining after Hermione in the same way, she could develop feelings for a different character, perhaps someone from another house who is intrigued by this new version of Ron.
