Well, in the context of fanfiction, 'itachi pins down and marks sakura' could imply a particular scenario within a story. Itachi is a character, and if he's 'pinning down and marking' Sakura, it might be a very specific action related to a plot in the fan - created story. Maybe it's a sign of possession or some kind of significant interaction in the fictional world of the fanfiction.
I'm not sure specifically about 'itachi pins down and marks sakura' fanfictions being popular. Fanfiction is a vast world, and while there may be stories with such a plot, it's hard to say if they are widely popular without doing a thorough search through fanfiction platforms. There are so many different types of Naruto - related fanfictions that it could easily get lost among the masses.
Fanfiction is fictional stories written by fans. In this case, it might be about a scenario where Itachi pins Sakura's wrists. It could be part of an action - filled, or perhaps a more complex and dramatic story within the fan - created world of the relevant anime or manga.
It could mean that in a creative or fictional context, Sakura's character development or some aspect of her is being shaped or influenced by fan - created stories about Itachi. Maybe in these fanfictions, certain scenarios or interactions with Itachi are used to mold Sakura's character in new and different ways that deviate from the original canon.
One possible interpretation could be a display of power. Itachi is a very powerful character, and pinning Sakura to the wall might be a way to show his dominance in the fictional scenario. It could also be a moment of shock or conflict, perhaps in a situation where their paths cross in an unexpected and tense way.
In the original Naruto storyline, Itachi and Sakura don't have such direct and extreme interactions. This fanfiction clearly takes a departure by creating this intense physical encounter. It adds a new layer of relationship that doesn't exist in the source material.
I'm not sure if it's a particularly popular type. There are so many different kinds of Naruto fanfiction out there, focusing on various relationships and scenarios. While the idea of Itachi and Sakura interacting in this way might be interesting to some, it may not be as widespread as other more common pairings or plotlines.
She probably changes in her mindset. Itachi's influence might make her think more strategically. Instead of just relying on brute force or basic medical ninjutsu, she could start to analyze situations better and come up with more effective solutions. For instance, she might learn from Itachi how to anticipate an opponent's moves based on their body language and chakra flow.
In this fanfiction, Itachi might help Sakura become stronger by training her in various ninja skills. He could teach her advanced genjutsu techniques. For example, he might start with the basics of detecting and breaking genjutsu, and then gradually move on to creating complex illusions herself. This would enhance Sakura's ability to defend against and use genjutsu in battles.
His possessiveness could be seen in his actions towards Sakura. He may be overly protective, like not allowing her to go on dangerous missions alone. He would always want to be the one to accompany her, ensuring her safety at all times. This shows that he doesn't want to share her with any potential threats that could come her way during a mission.
In fanfiction, being 'overprotective of sakura' might mean that a character is extremely cautious and defensive about Sakura. For example, a character could be constantly shielding her from any potential harm, whether it's physical danger like a battle or emotional harm such as mean comments from other characters. It could also be in a romantic sense where a love interest is overly possessive and doesn't want anyone else to get too close to Sakura.
