Well, I'm sure there exist fanfictions with that title or related concept. It really depends on how creative the fanfiction writers are. Some might focus on a very specific moment or aspect of Ron and Hermione's relationship and use this rather unusual description in a creative way. But also, make sure to follow the rules and guidelines of the fanfiction platforms to avoid any inappropriate content.
Expect different takes on their relationship. Maybe it's a story where Ron's action of 'fingers' (which could be interpreted in different ways like a gentle touch or a more significant gesture) is a turning point in their relationship. It could also be a story that blends this concept with other elements from the Harry Potter universe, like magic spells or adventures. However, again, be cautious as the quality and content can be diverse.
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.
Hermione, on the other hand, could become more vulnerable yet also stronger. She has always been strong - willed, but this experience could break her down initially. However, as she copes with the miscarriage, she might find new depths to her strength. She could become more in tune with her emotions and learn to lean on Ron more, which is a change from her usually independent self. This new dynamic between them would reshape their characters as they support and grow with each other through this difficult time.
Charlie might be a character who has known Hermione for a long time, maybe through some other connections in the wizarding world. He sees Hermione as someone in need of protection from Ron, whether Ron is acting out of his own accord or is being influenced by external forces. In relation to Ron, he is the one who stands against Ron's actions towards Hermione.
Hermione would likely be very angry at first. She is a strong - willed character and being kidnapped would go against all her principles of freedom and rights. She would probably try to reason with Ron immediately, using her logical arguments to make him see how wrong his actions are.
Well, Ron could have developed a more patient side to his personality. He's had experiences that taught him to be more understanding. Hermione may have become more laid - back. Maybe she realized that she was too uptight before. When they reunite, Ron's new - found patience helps him deal with Hermione's still - somewhat - controlling nature. And Hermione's more laid - back attitude allows Ron to feel more at ease around her. It's an interesting dynamic shift that can make for great storytelling in fanfiction.
I'm not a big fan of such dark fanfictions, but you could try looking on fanfiction.net. They have a large collection of Harry Potter fanfictions, and you might be able to find one with that plot there.
Fanfiction often takes creative liberties. So, if we consider the 'Snape fingers Hermione' scenario, it could be part of a plot where Snape is teaching Hermione a very intricate spell. His fingers might be guiding her hands in the correct movements, which is a very tactile and intense moment in the story.
One great 'Hermione and Ron Fanfiction' is 'The Missing Moment'. It beautifully fills in the gaps between their relationship in the original series. Another good one is 'Ron and Hermione's Adventure'. It takes them on a new magical journey that really showcases their bond.
