Maybe in some fanfictions, Ron is portrayed in a way that doesn't match Hermione's idea of him. For example, he might be made overly clumsy or insensitive, which could annoy Hermione.
Another reason could be that the fanfiction is full of clichés when it comes to their relationship. It always follows the same tired plotlines, and Hermione, being the intelligent and forward - thinking witch she is, is tired of seeing such unoriginal takes on their relationship.
Sometimes, the plotlines in fanfiction can be a bit outlandish. If Ron is constantly getting into trouble in a way that Hermione has to constantly clean up after him, it would be understandable for her to be fed up. This could be different from the more equal partnership they had in the original series.
Well, they could ask for Hermione's input! Just kidding. Seriously though, writers could break free from the traditional molds of how Hermione and Ron are portrayed in fanfiction. Explore different timelines or scenarios where their relationship isn't the main focus but still an important part of the story. Also, get rid of any misogynistic or one - dimensional portrayals of Hermione in the fanfics.
One common theme is the exploration of their personalities outside of the main story. In these fanfictions, we often see a deeper look into how Ron's insecurities play out in a relationship with Hermione, and how Hermione's strong - willed nature affects them as a couple.
Another theme is loyalty. Ron's actions in these fanfictions display his loyalty to Hermione. He doesn't let others mistreat her and is ready to face any consequences to protect her.
Without more context, it's hard to say exactly who Harry is. But given the phrasing, it could be a reference to Harry Potter, as he is a very well - known character who is often the subject of fanfiction.
One possible story could be that in these 10 months, Ron and Hermione are on a mission together. They face many challenges that test their relationship. Maybe they have to deal with a dark wizard threat and in the process, their bond deepens as they rely on each other's strengths.
There's also 'Ron and Hermione: A New Chapter' which focuses on a different scenario where they get together earlier than in the original series. The author does a great job of building their relationship in a more fast - paced yet believable manner. It has some really cute moments between them that fans of the pairing will enjoy.
