In this type of fanfiction, the plot could revolve around Sasuke's vampire nature making him possessive. Sasuke could be part of a vampire clan that has certain rules about relationships. When he falls for Sakura, a human, he defies those rules. His possessiveness could stem from his fear of losing her to either other vampires or the human world. Sakura, on the other hand, might be initially scared but gradually come to love Sasuke despite his overbearing possessiveness. There could be a lot of internal and external conflicts, like battles with other vampires who oppose their relationship and Sakura's struggle to maintain her own identity while being with Sasuke.
Well, in a possessive vampire Sasusaku fanfiction, it could start with Sakura being a human who is somehow aware of the vampire world. Sasuke, a powerful vampire, saves her from some danger. From that moment on, he feels a strong connection and possessiveness towards her. He might even go as far as marking her in some vampire - way to show that she belongs to him, and this could lead to a lot of drama as Sakura tries to come to terms with this new situation.
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.
Sasuke can be possessive of Sakura in fanfiction through his actions. He might constantly keep an eye on her during missions, not just for her safety but also because he doesn't want her attention to stray. He may also be possessive in terms of her emotions, wanting her to focus all her love and care on him alone.
One possible analysis is that in such fanfiction, the possessiveness might stem from the deep emotional bond between Sasuke and Sakura. Their relationship in the original Naruto series has many layers, and fanfiction often explores the more extreme emotions. For example, Sasuke's aloof nature might be countered by Sakura's strong will in a possessive relationship, creating a lot of interesting character dynamics and storylines.
One aspect of Sasuke and Sakura dark possessive fanfiction could be the exploration of their complex relationship. In some fanfictions, Sasuke's dark side might manifest as an over - protective or possessive nature towards Sakura. This could be due to his past traumas and his fear of losing her. It adds a new layer of intensity to their relationship that we might not see as much in the original series.
I would also recommend 'Sasuke's Dark Claim'. This fanfic explores the idea of Sasuke's dark side taking over when it comes to his feelings for Sakura. It has some really interesting plot twists and great character development for both of them.
Common themes in such fanfictions include the idea of ownership. It's not in a literal sense, but more of an emotional ownership. Sakura might feel that Sasuke is 'hers' after waiting for him for so long. And Sasuke might have a similar feeling towards Sakura. Another theme is the struggle with independence. Their possessiveness can sometimes clash with the other's need for independence. For example, Sasuke is a very independent character, but if Sakura is too possessive, it can create a conflict. Also, there's often the theme of redemption. Sasuke might be possessive as a way to redeem himself for all the pain he has caused Sakura in the past, by making sure he is the only one in her life now.
Love and devotion are also key themes. The possessiveness is really a manifestation of their deep love. In these fanfictions, their love is so intense that it turns into possessiveness. They are devoted to each other and the fanfiction might show how they handle situations where that devotion is tested, such as when they are separated or faced with difficult choices.
Protectiveness. Sasuke has seen a lot of danger in his life. He knows Sakura is a valuable person, both as a friend and as someone he cares about. So his possessiveness could stem from his desire to keep her out of harm's way. He doesn't want any bad guys to get near her.
Another aspect could be that Sakura's pregnancy changes Sasuke in some ways. He might become more in touch with his human side, realizing the importance of family. They could also face internal struggles within their relationship. For example, Sasuke might be afraid of hurting Sakura or the baby accidentally because of his vampire strength. But through it all, their love for each other and the anticipation of their new family member keeps them going.
One possible plot could be that Sasuke and Sakura, both being football fans, accidentally meet at a local football match. They start arguing about which team is better. But as the game progresses, they find themselves getting along and sharing their love for the sport. Eventually, they decide to form a small football club together with their friends in the village.
One possible plot could be that Sasuke gets injured during a mission and is brought to the hospital where Sakura works. Sakura then uses her medical skills to treat him, and during his recovery, they have deep conversations that rekindle their old feelings for each other.
