First, you need to understand the characters of Sasuke and Sakura well. For Sasuke, emphasize his brooding and powerful vampire traits, which could translate into his possessiveness. For Sakura, show her strength and how she reacts to Sasuke's possessive behavior. Also, create a vivid vampire world setting with its own rules and hierarchies.
One common theme is the struggle for power. The vampire, being possessive, often tries to assert his dominance over the reader, which can lead to power struggles within their relationship. Another theme is the idea of eternal love. Since vampires are often seen as immortal, the possessive nature can be related to the concept of loving the reader for all eternity.
One common trope is the 'forbidden love' aspect. Since Atem is a vampire, their relationship might be seen as taboo in the story's world. Another trope could be the 'damsel in distress' where Yugi is constantly in need of Atem's protection due to his vampire - related enemies. However, this can be subverted where Yugi is actually strong in his own right.
In such fanfictions, the setting often plays an important role. It could be a dark, gothic world where vampires are part of the hidden society. Yugi might initially be unaware of Atem's true nature as a vampire. As the story progresses, he discovers it and has to come to terms with Atem's possessive behavior. This could lead to conflicts between them as Yugi tries to maintain his own identity while also being in a relationship with a possessive vampire.
One possible plot could be that Sasuke is a vampire who becomes possessive over Sakura. Maybe he initially tries to resist his feelings for her because he's a vampire and he thinks it's dangerous. But as time goes on, he can't help but be drawn to her and becomes extremely possessive, scaring away any potential rivals.
There's also 'Dark Lover' by J.R. Ward. It's a very intense and passionate vampire romance. The characters are well - developed, and the story is full of action and drama. The relationship between the main characters is complex and full of the kind of dark, brooding love that is characteristic of this genre.
The 'Black Dagger Brotherhood' series by J.R. Ward is also great. It features a group of vampire warriors and their romantic entanglements. The series is known for its complex characters and exciting storylines that combine action and romance.
There's also 'The Vampire's Claim'. This fanfic has a possessive vampire who will stop at nothing to keep the reader by his side. It delves deep into the vampire's psyche, showing how his possessiveness stems from his deep - seated feelings for the reader. The story is filled with drama and some thrilling chase scenes where the vampire fends off other threats to the reader.
The vampire characters are usually very alluring. They have a certain charm, often being depicted as handsome or beautiful with a sense of mystery. In many of these books, like in the 'Black Dagger Brotherhood' series, the vampires' physical attractiveness is part of what draws the human or other non - vampire characters to them. They also tend to have special powers, which can make the relationships more interesting as the human character has to navigate this new and often dangerous world of the vampires.
'Wuthering Heights' can also be considered. Heathcliff's possessive love for Catherine is intense and tragic. The novel explores the dark side of love and possessiveness set against the wild moors.
