The teachers at Hogwarts would have different reactions. McGonagall might be disappointed in Hermione's choice, seeing it as a disruption to the harmony of the school. She might also be concerned about the potential for drama and distraction. Dumbledore, on the other hand, would be more understanding. He would likely see it as a complex emotional situation and might try to guide Hermione through it. Snape himself would be in a very difficult position. He's not used to this kind of attention and might initially reject Hermione's feelings out of self - preservation and his own past traumas.
In this fanfiction, perhaps Hermione dumps Ron after realizing that he doesn't support her academic pursuits as much as she thought. Snape, on the other hand, might recognize Hermione's potential and offer her unique opportunities to study advanced magic. This makes Hermione see Snape in a new light. As for Ron, he may initially be angry and confused but later come to understand that Hermione and he were not as compatible as he believed.
At the beginning, Ron would likely be in shock. He had always thought he and Hermione had a special bond. After the shock, he might become a bit bitter. However, his friends, like Harry, would probably try to cheer him up and help him see that there are other things in life. Eventually, Ron might find a new purpose in his life, whether it's in his magical studies or in exploring new parts of the wizarding world, and try to move on from Hermione.
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.
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.
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.
Harry would also be very protective of Hermione. He would likely step in between Molly and Hermione, using his status as the Boy Who Lived if necessary to defuse the situation. He might try to reason with Molly, reminding her of all the good things Hermione has done for them and for the wizarding world.
Hermione would probably be deeply hurt at first. She trusts Harry and Ron so much, and being abandoned by them would be a huge blow. But she's also very determined. So, she might throw herself into her studies even more, using her knowledge as a way to cope and also to find a solution to the situation.
Ron would probably be horrified. He loves Hermione deeply, and his mother has always been an important figure in his life. He would be caught in a really difficult situation. He'd likely try to stop his mother immediately and protect Hermione.
At first, Harry might be confused. He would try to figure out what went wrong. He might search his memory for any signs that could have led to this betrayal. Then, he would likely experience a range of emotions from sadness to rage. Depending on the nature of the betrayal, he could either try to win them back by showing them the truth or decide that they are no longer worthy of his friendship and focus on his own path, maybe even leaving the wizarding world for a while to clear his head.
