Itachi is a very complex and reserved character, while Sakura is strong - willed. Their relationship could start with Itachi being somewhat of a mentor to Sakura in terms of combat strategy. Sakura would be intrigued by Itachi's calm and calculating nature. As they spend more time together, Sakura might start to see the softer side of Itachi that he hides from most, and this could lead to a deeper connection.
One plot idea could be that Itachi, in a different timeline where he didn't face all the tragedies so soon, meets Sakura during a mission outside the Leaf Village. They initially start as rivals but gradually come to respect each other's skills. As time passes, they find themselves working together more often and develop a deep friendship that slowly turns into a romantic relationship.
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.
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.

A story where Shisui survives and he meets Sakura during a mission outside of Konoha. Sakura is initially wary of him because of his Uchiha heritage, but Shisui's gentle nature quickly wins her over.
