One possibility is that the snakes are under a spell. They wrap around Sakura because she has a certain energy or power that attracts them. In the fanfiction, this could lead to Sakura having to figure out why the snakes are drawn to her and how to break the spell on them. It could involve her using her medical ninjutsu skills or her inner strength that she has developed over time.
Perhaps in this fanfiction, the kabutos snakes are a new species that has just been discovered. They wrap around Sakura as a form of communication. Sakura, being the intelligent and curious character she is, tries to understand what the snakes are trying to convey. This could lead to an adventure where she has to explore a new part of the ninja world with the snakes as her guides, learning about their culture and how they can co - exist with humans.
The antagonist could be a dark force that has corrupted the snakes. In the fanfiction, this dark force might be trying to use the snakes to harm Sakura. It could be an ancient evil that has been awakened and sees Sakura as a threat to its plans. So it uses the snakes, which were originally neutral or even friendly, to try and get rid of her.
Perhaps the story could revolve around Deidara using his clay to create something special for Sakura. He could use his artistic skills with the clay to make a gift for her. This might lead to a strange friendship between them as Sakura is initially suspicious but then comes to appreciate his creativity.
In this fanfiction, it could be that Sasuke has lost his mind due to some traumatic event. He ties Sakura with snakes because he sees her as a symbol of the world he wants to reject. The snakes could represent the chaos and danger that he now associates with her. Meanwhile, Sakura might be in shock at first, but then she starts to analyze the situation. She realizes that Sasuke is not in his right mind and tries to use her medical knowledge and ninja skills to not only free herself but also to heal Sasuke's broken psyche.
One possible plot could be that Sasuke, with his snake - related powers or abilities, restrains Sakura in a non - harmful way as part of a training exercise. He might be trying to teach her how to break free from unexpected restraints in battle situations. For example, he could use his snakes to hold her arms gently while she tries to use her medical ninjutsu skills and strength to escape.
The plot could involve a prophecy that ties the kabuto snakes' coils to the sakura. A chosen one is destined to bring together the power of the snakes' coiled forms and the essence of the sakura. Maybe the snakes' coils hold a map or a code that is inscribed on the petals of the sakura, and the protagonist has to decipher it to save their world from an impending doom.
The plot could involve Kabuto sending his shadow snakes to steal a valuable scroll from Sakura. Sakura uses her fan to defend the scroll. The fan could have some hidden abilities that she discovers during the fight, like the ability to create illusions that make the snakes attack each other.
The plot could be about a magical world where Kabuto snakes are guardians of a sacred sakura tree. The snakes coil around the sakura to protect it from dark forces. A young hero discovers this and has to convince the snakes to let them pass in order to gain a special power from the sakura.
The sleeve snakes coiling sakura could be part of a love story. A snake spirit falls in love with a spirit of the sakura tree. They are from different worlds but their connection is so strong that the snake coils around the sakura as a sign of eternal love. However, there are forces that try to separate them, leading to a series of adventures and challenges for the two lovers.
Maybe Orochimaru's tongue - wrapping is part of a test or trial for Sakura. He might be an unexpected ally in a situation where Sakura has to prove herself worthy of a new level of power. His tongue could wrap around her as a way of connecting their minds, and through this connection, Sakura has to face her inner fears and insecurities. Once she overcomes them, she emerges with newfound confidence and abilities, and Orochimaru, for his part, gains some respect for her tenacity.
I'm not sure specifically as it depends on the particular fanfiction. But generally, it might involve Sakura facing challenges while in some sort of situation with snakes. Maybe she's trying to escape from their coils or deal with some power related to the snakes.
