It could signify the deep trust they have in each other. Falling asleep next to someone requires a certain level of comfort and security, and in the case of Ron and Hermione, it shows that they feel safe in each other's presence.
One scenario could be that they are in the Gryffindor common room. After a long day of studying for exams, they sit by the fireplace. As they talk about their future dreams, they start to feel drowsy. Hermione leans on Ron's shoulder and they both slowly fall asleep, with the warm glow of the fire creating a cozy atmosphere around them.
Their relationship might develop through shared adventures at Hogwarts. They face challenges together, like fighting dark magic or helping their friends. This builds a strong foundation of trust and mutual respect, leading up to the moment when they fall asleep together.
I'm not sure if there is such specific fanfiction. Fanfiction varies widely in content and themes, and while the 'Ron and Hermione' pairing is popular in the 'Harry Potter' fandom, a scenario of them showering together might be considered rather unorthodox and not all that common. You could try searching on major fanfiction websites, but don't be surprised if it's not easy to find.
One reason could be that they still love each other but just had a misunderstanding before. Once that misunderstanding is cleared up, they naturally get back together.
You can find 'Ron and Hermione together' fanfiction on websites like Fanfiction.net. It has a large collection of stories about various pairings in the Harry Potter universe, including Ron and Hermione. Another great place is Archive of Our Own (AO3). It has a well - organized tagging system, so you can easily search for Ron and Hermione - centric fanfics.
There's a fanfic called 'Ron and Hermione's Unseen Adventures'. In this one, they go on secret missions that weren't part of the original books. It's really exciting as it shows their teamwork and how their relationship grows stronger through these challenges. Also, 'The Love Story of Ron and Hermione' is a simple yet heartwarming tale that focuses mainly on their relationship development, from the first spark of love to a deep, abiding connection.
One great fanfiction could be 'A New Beginning for Ron and Hermione'. It shows their life after the war, how they slowly realize their feelings for each other and start a relationship. It has really sweet moments like their first date in a wizarding café.
There might be some fanfictions that handle their relationship in a more innocent, platonic way that could be considered suitable for all ages. However, the idea of 'sleep together' can be misconstrued, and most official works keep their relationship in a more PG - 13 realm. You can try searching on family - friendly fanfiction platforms and look for stories that focus on their emotional bond rather than any improper interpretations.
There's 'Sooner Than Expected'. In this fic, a series of events at Hogwarts, like a shared adventure in the Forbidden Forest in their third year, makes Ron and Hermione see each other in a new light and they get together earlier. It has a lot of cute moments between them and also stays true to the overall feel of the original series.
