I'm not sure who Aidou Hanabusa specifically is. It could be a name from a very specific anime, manga or some other form of media that I'm not familiar with. Without more context, it's hard to tell the love story.
Some of the best authors are the ones who can make you feel the emotions that Hanabusa is experiencing. Whether it's his love, his anger, or his confusion, they can write in a way that makes you empathize with him. They might use detailed descriptions of his thoughts and actions to bring his character to life in their fanfictions. You can often find these authors by looking at the reviews and ratings of different fanfictions.
In some fanfictions, Hanabusa and Yuki's relationship could be explored in a more romantic light. Hanabusa's long - standing admiration for Yuki might lead to some really sweet and tender moments between them. For example, he could write her a poem expressing his feelings in a really old - fashioned and charming way.
Well, I've come across some where Hanabusa Aido is in a really different setting than the original story. For example, in one fanfiction, he's in a modern-day high school but still has his vampire charm. The 'lemon' aspect might imply some romantic or spicy elements, which are often used to explore his character's deeper emotions and relationships in a more intense way.
One common theme is his love and loyalty. Since he's a passionate character, many fanfictions explore his deep - seated feelings for others. Another could be his struggle with his vampire nature, and the 'lemon' part might add a touch of sensuality to these internal battles.
One interesting Vampire Knight Hanabusa fanfiction could be about his hidden powers. Maybe he discovers a new ability that changes his role within the vampire world. It could involve him using this power to protect his friends and deal with the complex vampire - human relations in the story.
A common theme is the exploration of unrequited love. Since Yuki has complex relationships with other characters in the original Vampire Knight story, fanfictions often play with the idea of Hanabusa loving Yuki from afar while she is preoccupied with others. This creates a lot of emotional tension.
A common theme is romance. Given that it's a character x reader type of fanfiction, there's often a focus on the developing relationship between the reader and Aido Hanabusa. It could be a slow - burn romance where they gradually fall for each other.
