Moony might be protective of Hermione because he has a strong sense of justice. In the wizarding world, Hermione is a Muggle - born, and she often faces discrimination. Moony, being a member of the Order of the Phoenix, is against all forms of prejudice. He would naturally want to protect her from any harm, whether it's from Death Eaters or just general bigotry within the wizarding community. Also, Hermione's intelligence and her role in fighting against the dark forces make her an important asset, and Moony would understand the need to safeguard such a valuable ally.
Moony might start to avoid Tonks while getting closer to Hermione. He could form a study group or some sort of alliance with Hermione, leaving Tonks out. This would create a rift between Tonks and Moony, and a bond between Moony and Hermione.
One common theme is mentorship. Since Moony is older and more experienced, often in fanfics he acts as a mentor to Hermione, guiding her in her magical studies or in dealing with the challenges of the wizarding world.
Well, it could be about a situation in a fan - made story where Harry is bitten by a character named Moony. Maybe it's set in the Harry Potter fanfiction universe, and this event leads to a whole new set of adventures or challenges for Harry, like dealing with the consequences of the bite, which could be magical in nature or related to some sort of transformation.
One common theme is the exploration of an unexpected friendship. Since they are from different generations in the wizarding world, seeing how they bridge that gap is often explored. For example, Hermione's modern - thinking and Moony's more traditional ways.
It could be that Tonks represents something Moony doesn't like. Perhaps she's associated with a group or an idea that he opposes. On the other hand, Hermione is known for her loyalty and her ability to think on her feet. Moony might value these qualities and thus like her in the fanfiction.
I'm not sure specifically as there could be many different fanfictions with this title. It might be about an encounter where Harry Potter is bitten by a character named Moony (presumably Remus Lupin as his werewolf name is Moony in the Potterverse). But without reading it, it's hard to say more.
In some fanfictions, during battles at Hogwarts, Moony is often shown as standing in front of Hermione to shield her from dark spells. For example, when Death Eaters attack the school, he might push her out of the way of a Killing Curse. Another instance could be when Hermione is being bullied by some Slytherins for being a Muggle - born. Moony steps in and scares them away with his werewolf - like presence. He also might accompany Hermione when she has to go to some dangerous places, like the Forbidden Forest at night, to protect her from any lurking creatures or dark wizards.
There's a fanfiction called 'Hermione and Moony: A Forbidden Friendship'. It delves deep into the relationship between them in a world where their friendship is not easily accepted. It shows how they support each other through various challenges in the wizarding world. It's quite engaging as it also brings in other familiar characters from the Harry Potter series to add more depth to the story.
Another place could be Fanfiction.net. However, the tagging system there might not be as precise as on AO3. But it's still worth a shot. Look for the relevant character names in the search bar and browse through the results. Some fanfic authors also post about their works on social media platforms like Tumblr or Twitter, so you could search there too. Maybe search for '#fem Harry #Moony #fanfiction' on Twitter for example.
