A plot could be that after a great war, they decide to rebuild their village together. Naruto as the leader, Sasuke as his right - hand man in security matters, and Sakura in charge of the medical and educational aspects. Working side by side day in and day out, they develop a deep friendship. They have regular meetings where they not only discuss village matters but also share personal anecdotes, which makes their bond grow stronger.
There could be a fanfiction where they are chosen for a special project. This project requires them to travel to different lands and learn about new cultures. During their travels, they have to live together in small lodgings. This forces them to interact on a more personal level. Naruto might make them laugh with his silly antics, Sasuke would offer his silent support, and Sakura would take care of their well - being. All these experiences bring them closer together.
Imagine a fanfiction where Sasuke gets injured badly and Naruto and Sakura take care of him. Naruto goes out of his way to find rare herbs for Sasuke's recovery, while Sakura uses her medical skills to heal him. During this time, Sasuke realizes how much they care for him. After he recovers, he is more open and friendly towards them. They start to do things together like having picnics or training in a more relaxed way, which leads to a closer relationship.
