I'm not sure specifically if there are super - popular ones with that exact title. But there are likely many Naruto - based fanfics where Sakura has some sort of strained relationship with Team 7. You'd have to search through fanfic platforms like Archive of Our Own or FanFiction.net to find out.
It could mean that in a fan - created story (fanfic), Sakura is depicted as ignoring Team 7. Maybe she has some sort of conflict or just a personal choice within the context of that particular fan - written narrative.
He might be initially confused. Sasuke is not used to Sakura ignoring him as she has always been somewhat persistent in her attention towards him. So, he may be at a loss as to why she is suddenly acting this way.
Sakura might initially be confused. She would probably wonder why Naruto is acting this way all of a sudden. For example, she might try to get his attention by calling his name a few times, but when he doesn't respond, she could be left feeling a bit bewildered.
In some fanfics, Naruto may ignore Sakura because he has his own emotional traumas to deal with. He might find Sakura's presence a reminder of things he wants to forget or move past, so he chooses to keep his distance. For example, if he has faced a lot of rejection from her in the past, he could decide to just cut her out of his life.
There is a fanfic titled 'Naruto's Solo Journey' where Naruto decides to distance himself from Sakura. He believes that she is too focused on Sasuke and he wants to carve his own path without getting involved in their drama. This makes for an interesting read as it shows Naruto's growth in a different light.
She could be confused at first. She might not understand why Naruto is suddenly ignoring her, since they were friends before. So she might try to approach him to ask what's wrong.
One possible reason could be that Sakura has finally grown tired of Sasuke's aloof and cold behavior towards her. She might have realized that she has been constantly chasing after him while getting little in return, so she decides to ignore him as a form of self - preservation.
A sakura team 7 fanfic can cover a wide range of topics. It could be a rewrite of certain arcs in the Naruto story from Sakura's perspective. For example, during the Chunin Exams, it might show her internal thoughts and fears more in - depth. It may also create new storylines for Team 7, where Sakura plays a more central role, perhaps in a new threat to the Hidden Leaf Village that only she can help solve because of her unique skills as a medical - ninja and her combat abilities.
A 'sakura different team fanfic' might be about different teams in a fictional world inspired by sakura. Maybe there are teams of magical beings or warriors. The fanfic could explore their unique abilities, their quests, and how they interact with each other. For example, one team might be protectors of the sakura forest while another is trying to use the sakura's power for their own gain.
