The relationship might be full of comical moments. Ron's attempts to stay close to Hermione could result in all sorts of humorous situations, like accidentally ruining her study time or getting in the way of her other plans.
One possible reason could be that Ron has deep - seated feelings for Hermione that he's not fully aware of yet. In the story, he might be subconsciously drawn to her and thus won't leave her alone.
Well, it could be for love. In many fanfics, their relationship has been through a lot, and leaving together is a way to start anew, away from the prying eyes and pressures of Hogwarts and the wizarding community.
In this fanfiction scenario, their relationship dynamics would change significantly. Since they are siblings, they would probably grow up together. This means they would share more childhood memories, both good and bad. Hermione might be more protective of Harry and Ron as her brothers, and she could use her intelligence not just as a friend but as a sister to keep them out of trouble. Ron would also be more possessive in a brotherly way. They would also face family - related issues together, like dealing with their parents' expectations or family secrets.
Perhaps she tries to find them right away. Using her intelligence and resourcefulness, she starts to search for any clues as to where they might have gone. She could ask other friends, like Neville or Luna, if they have seen Harry and Ron. And she might be determined to bring them back, not willing to give up on their friendship easily.
The relationship could be a bit tense at times. Steve is very by - the - book and Tony is a bit of a maverick. But there would also be a lot of love. Steve would see Tony as someone he needs to protect and guide, and Tony would respect Steve's wisdom, even if he doesn't always show it.
In fanfiction, it could be that Charlie has a more mature understanding of Hermione's intellectual pursuits. Ron sometimes struggles to keep up with Hermione's thirst for knowledge. Charlie, with his own expertise in his field, might be able to engage Hermione in more in - depth conversations, leading her to consider a relationship with him instead of Ron.
It's likely to be a very tense relationship dynamic. Harry would surely be angry and confused about being tied to the bed by Snape, which would lead to a lot of conflict between them. Snape, on the other hand, might be acting out of what he believes is right, but his actions are invasive.
A father - daughter like relationship could be expected. Sirius, having lost so much in his life, might see Hermione as someone he can care for and protect, much like a daughter. He could be very protective of her and give her advice on how to navigate the complex wizarding world.
One possible reason could be a misunderstanding. Maybe they misinterpreted something Hermione said or did, and in a fit of anger or confusion, they decided to leave. For example, if Hermione was working on a project alone without consulting them, they might have felt left out and left in a huff.
If Ron and Hermione leave Harry in the fanfiction, it would change the entire fabric of the story. Harry would have to reevaluate his relationships with other characters. For example, he might turn to Neville for support more often. Also, the power dynamic within the wizarding world could shift. Since Ron and Hermione were important figures in the fight against Voldemort, their absence could give the Death Eaters an advantage, or it could inspire others to step up in unexpected ways. Harry would be forced to grow in ways he hadn't before, and it would be a journey full of self - discovery and new challenges.
