Perhaps Naruto is being influenced by an outside force. It could be an enemy who has tricked him into believing that his team is holding him back. Or it could be that he has fallen into a dark state of mind, like if he has some kind of mental breakdown due to all the pressure he has faced in the past. In this state, he might just push Team 7 away without really meaning to in the long run.
The plot might involve Naruto being influenced by some external force. For example, a new enemy could be using some kind of mind - control or illusion on him to make him ignore the Rookie 9. Another possibility is that Naruto has become so focused on his training to become stronger that he starts to neglect his relationships with the Rookie 9, thinking that his power is more important for the future of the village.
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.
It could be Orochimaru. He's always been interested in Naruto and might come up with a plan to drive a wedge between Naruto and the Rookie 9. By making Naruto ignore them, he could be trying to isolate Naruto and make him more vulnerable to his attacks or manipulations.
Often in fanfiction, Naruto ignores his family when he becomes obsessed with power. He may think that the power he gains is more important than his family ties. For example, if he discovers a new form of chakra or a new jutsu, he might seclude himself to master it, ignoring his family's concerns. This can lead to his family feeling neglected and trying to bring him back to his senses.
Maybe he got some kind of curse. In the Naruto universe, there are all sorts of dark magic and curses. If he was cursed, it could make him withdrawn and cause him to ignore everyone.
In the original Naruto story, family is an important theme. However, in this fanfiction where Naruto ignores his family, the emotional core of the story shifts. The relationships that were built on family bonds are now broken. This can have a ripple effect on the whole plot. For instance, the support system that Naruto had from his family in the original story is no longer there. So, he has to face challenges alone, which may change the way he approaches battles, makes decisions, and interacts with other characters in the Naruto universe.
In some fanfictions, Naruto ignoring his family can be a plot device to create drama. It might be due to misunderstandings. For example, if there's a miscommunication about his ninja duties and family expectations. This can lead to a more complex and angsty storyline as Naruto has to face the consequences of his actions, like strained relationships with his family members.
The scenario where Team 8 saves Team 7 instead would be quite interesting. It could introduce new conflicts and resolutions, and potentially reveal hidden strengths of Team 8 that weren't previously showcased.
