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.
In fanfiction, this kind of plot twist can be really interesting. It might be due to the author wanting to explore different character dynamics. Maybe Hermione realizes she has a stronger connection with Sirius in terms of his more adventurous spirit or his different life experiences compared to Ron.
One possible reason could be that in the fanfiction, Bill might be depicted as more mature and worldly compared to Ron. Hermione may be attracted to his experience and the different perspective he can offer.
The relationship changes drastically. Hermione may start to view Ron as someone she once knew well but has now grown apart from. Ron, on the other hand, may go through a range of emotions from denial to anger to sadness. Their friendship that was the foundation of their relationship may also be damaged, and they may have to re - evaluate how they interact with each other in the wizarding community.
One reason could be that Sirius represents a sense of freedom and rebellion that Hermione finds appealing. He's been through a lot and has a certain non - conformist attitude. In contrast, Ron can be a bit more traditional in his views at times.
The relationship between Hermione and Ron in this fanfiction takes a sharp turn. It goes from a relationship (presumably) full of the usual bickering and affection they have in the original series to a complete break - up. Hermione's feelings shift towards Bill, leaving Ron behind.
One reason could be for the sake of creating drama. By showing Ron as controlling, it adds tension to the story. Another might be a misinterpretation of his character traits. If an author emphasizes his protective side too much, it could come across as controlling.
Hermione Jean Granger and Ron Weasley were both important characters in the Harry Potter series. They formed the magical trio with Harry Potter and were very good friends. This friendship had been tested for seven years and experienced many adventures together. Ron was the child of a pure-blood wizarding family. He was humorous, brave, kind, with flaming red hair and blue eyes. Hermione was Muggle-born, intelligent and studious, with thick, unkempt brown hair and brown eyes. During their time at Hogwarts, they faced various challenges together, such as protecting the Sorcerer's Stone, finding the entrance to the Chamber of Secrets, and helping Sirius. They had also fought side by side on the journey to find and destroy Horcruxes, with Ron successfully destroying the Horcrux locket and Hermione successfully destroying Hufflepuff's Gold Cup. Ron and Hermione also fell in love, and they eventually married and had two children. In Harry Potter and the Cursed Child, they had different experiences in different time lines. For example, in a certain time line, they sacrificed themselves to help Skopis return to the present, and they confessed their love to each other when the dementors approached. Harry Potter and the Prisoner of Azkaban wasn't enough. Everyone, please click to read the novel!
Another aspect could be Ron's jealousy issues. In the original story, Ron sometimes gets jealous of Hermione's friendship with Harry or her academic achievements. In fanfiction, this jealousy could be exaggerated to a point where Hermione can't tolerate it anymore and thus is written as hating him. For example, if Ron constantly tries to undermine her success out of jealousy, it would be a valid reason for her to develop strong negative feelings towards him.
In these fanfictions, a common theme is change. Hermione's life changes drastically when she leaves Ron for Charlie. There may be a theme of new beginnings, as she embarks on a relationship with someone very different. The idea of finding a better fit is also there. Maybe she realizes that Charlie understands her more or can offer her more support in certain areas. Additionally, themes related to family and acceptance can come up, especially if the story delves into how the Weasley family reacts to Hermione's choice and how Charlie's side of the family accepts her.
Yes, it can be a somewhat popular trope. Some fans might like the idea of Hermione ending up with Charlie because he represents a different kind of character compared to Ron. Charlie is often seen as more adventurous and perhaps less argumentative. It allows for new storylines and character developments that deviate from the original series. Writers can explore how Hermione's relationship with Charlie would change her and how their combined skills and personalities would interact in different ways than her relationship with Ron did.
