One possible plot could be that Charlie comes back to Hogwarts for some reason, maybe to help with a dragon - related problem. Hermione, being the brilliant witch she is, is also involved in the solution. As they work together, they start to develop feelings for each other and eventually share a kiss. Maybe it's a moment of celebration after they successfully solve the problem.
In a different plot, there could be a magical accident that causes Hermione and Charlie to swap memories or some part of their personalities. As they try to figure out how to reverse it, they have to spend a lot of time together. During this time, they get to know each other on a deeper level. Charlie is impressed by Hermione's intelligence and Hermione is drawn to Charlie's adventurous spirit. The kiss could be a moment of realization that their feelings for each other are real, despite the strange circumstances that brought them together.
The plot might involve Hermione going on an exchange program to study magical creatures in a different country where Charlie is based. They meet and Charlie shows Hermione around the dragon habitats. As they spend time together, they discover they have a shared love for protecting magical creatures and a mutual respect for each other's knowledge. Eventually, they become friends and help each other out in various ways, like Hermione helping Charlie with some paperwork using her organizational skills.
Perhaps in this fanfiction, Hermione discovers that Charlie has a hidden love for music. She decides to sing to him as a way to get closer to him. Their relationship might start as a friendship, but the act of singing could lead to deeper feelings developing between them over time.
Maybe Hermione gets involved in a situation where she needs to rescue a magical creature, like a baby dragon that has been captured by poachers. Charlie, being an expert in dealing with dragons, comes to her aid. They embark on a dangerous journey to find the poachers' hideout. Along the way, Charlie teaches Hermione some survival skills in the wild, as well as how to communicate with dragons on a basic level. In the end, they rescue the baby dragon and Hermione has a newfound respect for Charlie's skills.
One possible plot could be that Hermione gets injured during a dangerous magical experiment. Charlie, with his extensive knowledge of magical creatures and their healing properties, uses a rare potion made from a dragon's scale, which he obtained during his dragon - handling days in Romania. He combines it with some traditional healing spells to slowly heal Hermione's wounds.
Maybe in the fanfiction, Charlie realizes Hermione is cute when he sees her standing up to Draco Malfoy one day. He admires her courage and starts to notice other things about her, like the way she tucks her hair behind her ear when she's concentrating. As he gets to know her better, he discovers they have a shared love for adventure. They might go on a secret mission together where their relationship deepens.
In fanfiction, when Hermione flirts with Charlie Weasley, it might bring out a different side of Hermione. She's usually so studious and serious, but the flirtation could show her more playful and daring side. Charlie, on the other hand, might be a bit taken aback at first but then warm up to it. They could end up sharing their knowledge with each other, Hermione with her magic theory and Charlie with his dragon lore.
In fanfiction, Hermione and Charlie could have a very adventurous relationship. They might team up to study some rare magical creatures. Since Charlie has a passion for dragons and Hermione loves knowledge, they could go on expeditions together. Charlie could introduce Hermione to the world of dragon keeping, and Hermione could use her intelligence to help Charlie with research on dragon behavior.
If there was a non - inappropriate fanfiction with Charlie Weasley and Hermione, it could be about Charlie teaching Hermione something about magical creatures. Since Charlie has a lot of experience with dragons in Romania, he could be showing Hermione some unique dragon - related magic that she's never seen before. Their interaction could be a friendly exchange of knowledge, with Hermione being her usual inquisitive self and Charlie being the patient teacher.

I'm not sure if there is a specific fanfiction with that exact title. There are a vast number of Harry Potter fanfictions out there, and while some might involve Charlie Weasley and Hermione in some way, it's hard to say if one has that rather odd - and perhaps a bit concerning - description. It could be a very niche or even a made - up idea for a fanfic that may or may not exist.
