Well, it could be a story where Hermione is on a mission to study werewolves and Greyback is her main subject. At first, he is very uncooperative, but Hermione's determination and her unique way of seeing things start to change his perspective. Over time, a relationship forms that is not based on traditional mating but on mutual understanding and a shared goal of improving the situation of werewolves in the wizarding world. They might face opposition from both the wizarding society who fears werewolves and some of the more radical werewolves who don't trust Hermione.
A plot could revolve around Hermione being kidnapped by Greyback's pack. But instead of succumbing to fear, she uses her intelligence to gain the respect of some of the werewolves. Greyback is initially hostile but gradually becomes intrigued by her. Their relationship could then develop as Hermione tries to broker peace between the werewolves and the wizarding community. Maybe there's a prophecy involved that says only their union can bring peace, and they have to navigate the complex emotions and politics around it.
A possible plot could be that Hermione gets bitten by Greyback accidentally. Instead of turning into a full - blown werewolf, she has some new abilities and a strange connection to Greyback. They then have to figure out how to deal with this new situation, while also facing the wizarding world's prejudice against werewolves. It could also involve Hermione using her intelligence to find a cure for herself and in the process, changing Greyback's view of non - werewolves.
A possible plot is that Hermione, in her pursuit of equal rights for magical creatures, decides to reach out to Fenrir Greyback. At first, he is hostile, but Hermione's determination and her ability to see beyond his monstrous side start to change him. They could end up in a situation where they have to work together to stop a greater evil that is targeting werewolves and other marginalized magical beings. This would involve Hermione using her logical thinking and Fenrir using his knowledge of the werewolf underworld.
I'm not sure if there is such a specific fanfiction. It seems like a rather dark and unusual pairing considering Fenrir Greyback is a werewolf known for his brutality. However, the world of fanfiction is vast, and there might be some out there that explore this concept, but it's not a common or mainstream idea in the Harry Potter fanfiction community.
One plot idea could be that Fenrir, in his 'good' form, helps Hermione in her research on werewolves. He uses his insider knowledge to guide her in understanding the complex nature of lycanthropy, and they form an unlikely alliance against those who want to use werewolves for dark purposes.
One idea could be that Fenrir Greyback, instead of being a full - on villain, has some sort of complex relationship with Hermione. Maybe he's forced to protect her in a situation where they are both in danger from a greater dark force. This could lead to a lot of tension and moral dilemmas for Hermione as she has to deal with being around a werewolf who has a reputation for being cruel.
One plot idea could be that Fenrir Greyback, instead of attacking Hermione, is somehow magically bound to protect her. This could lead to a strange alliance where Hermione has to trust a werewolf known for his brutality. Another idea is that Fenrir has a change of heart due to Hermione's intelligence and courage, and he starts to fight against his dark nature for her sake. Maybe he could help Hermione in a battle against the Death Eaters by using his werewolf strength in unexpected ways.
One plot idea could be that Hermione discovers a hidden mark left by Greyback that has some sort of magical connection. Maybe it gives her insights into his past or his pack's secrets. Another could be a story where Hermione has to find a way to break the mark's hold on her or someone else it's affecting.
For Hermione, start with her initial fear and disgust towards Greyback due to his reputation. Then show how her inquisitive nature makes her look beyond the surface. As for Greyback, show his animalistic side at first, but also hint at a deeper, more human part that Hermione begins to uncover. For example, Hermione could notice how Greyback is protective of the younger werewolves in his pack, which makes her reevaluate him.

They could then embark on a journey to break a curse that is related to their mate bond, facing various challenges along the way, like dark magic and ancient creatures.
