One common trope is the 'Outcast Attraction'. Since Remus is a werewolf, he is somewhat of an outcast. Hermione, being the empathetic character she is, is drawn to him because she sees beyond his condition. This creates a sort of 'I'll save you' dynamic.
One popular fanfiction with this theme might be 'Moonlit Encounters'. In it, Hermione's feelings for young Remus develop gradually as they study together in the library late at night. The author beautifully portrays their budding relationship, with Hermione being drawn to Remus' quiet intelligence and his kind heart.
There are several common themes. One is the idea of acceptance. Remus has to accept that Hermione could love him despite his condition, and Hermione has to accept all of Remus, including his past and his insecurities. Another theme is the role of friendship in love. Often, their relationship starts as a friendship based on mutual admiration for each other's qualities. This friendship then slowly morphs into a deeper, romantic love. And of course, there's the theme of the wizarding world's backdrop, with elements like Hogwarts, magic spells, and other magical creatures playing important roles in their relationship's development.
A common trope is the 'forbidden love' aspect. Since Future Trunks has a lot of responsibilities and his situation is often complex, falling in love with a Saiyan can be seen as something that goes against his duties at times. Another trope is the 'power couple' idea. As both are Saiyans or related to Saiyans, they are often depicted as being extremely powerful together, both in combat and in their relationship.
One common theme is redemption. Draco often has to overcome his past prejudices and actions, and his love for Hermione becomes a part of that journey of self - improvement.
One possibility in such a fanfiction could be that the age difference between Remus and Hermione creates a complex dynamic. However, their shared love for knowledge and their kind hearts could be the initial attractions. For example, they might bond over a particularly difficult spell or a piece of magical history that others overlook.
One common theme is the exploration of their different personalities coming together. Remus is more reserved and experienced, while Hermione is bold and studious. Another theme is the magical aspect, like how they use magic together. Also, dealing with the challenges of the wizarding world as a couple is often seen.
One common theme is the age - gap relationship dynamic. Since Remus is older, there's often a sense of Hermione having to navigate her feelings in the face of this difference. Another theme is the exploration of Hermione's more emotional side, as she's usually portrayed as very logical in the original series. Here, her smitten state shows a different aspect of her character.
The 'alternate universe' trope is also common. In some fanfictions, the story might be set in a world where the normal rules of the Harry Potter universe don't apply. For example, there could be a world where age differences don't matter as much, or where Remus and Hermione are brought together in a different context, like they are on a secret mission together and their relationship blossoms during that time. There are also stories that might involve time - travel, where Hermione goes back in time and meets a younger Remus, which adds another layer of complexity to their relationship.
Yes, there are some great ones. You can start by looking on fanfiction platforms like Archive of Our Own. There are stories that beautifully explore their relationship, often delving into how Hermione's intelligence and Remus' more reserved nature interact. Some stories focus on them during the events of the original series, while others create alternate universes where their relationship can develop more freely.
One common trope is the 'slow - burn' where Ladybug gradually realizes her feelings for Chat Noir over time. Another is the 'identity reveal' leading to a new level of closeness. And the 'damsel in distress' where Chat Noir saves Ladybug and it sparks new emotions in her.
