In this type of fanfiction, Naruto leaving Team 7 can be a very emotional and plot - twisting scenario. It might lead to Hinata stepping up to support Naruto in different ways. For example, she could be the one to convince him to come back to the team eventually. Also, this situation can explore the deeper feelings between Naruto and Hinata as they are forced to deal with the change in their dynamic.
When Naruto leaves Team 7 in this Naruhina fanfic, it could set off a chain of events. Hinata might start training harder to be strong enough to support Naruto. Their interactions could involve Hinata sharing her own insecurities with Naruto, which makes him see her in a new light. This mutual sharing and support can be the foundation for a deeper Naruhina relationship, while also dealing with the consequences of Naruto's departure from the team.
Hinata would be heartbroken at first. Naruto is someone she deeply cares about. But she's also a strong - willed ninja. So she might start by trying to understand why Naruto left. She could look for clues in the village or talk to Naruto's friends to figure out his possible destination.
Well, one possibility is that Hinata decides to go after Naruto. She's in love with him, after all. She might leave Konoha too, in search of him. This could lead to a whole adventure where they meet new characters and face new challenges together. It would also be a chance for their relationship to develop further outside the constraints of the village.
Sasuke might become more withdrawn. He was always in a sort of rivalry with Naruto, and without Naruto there, he could lose some of his motivation to get stronger. Sakura would be devastated. She cared about Naruto, and his leaving would make her question what went wrong. Kakashi would also feel a sense of failure as a teacher.
One interesting plotline could be Naruto and Hinata facing a new and powerful enemy together as part of Team 7. This would test their skills and also their relationship. Another could be a time - travel plot where they go back in time and change some events in Team 7's history, which in turn affects their relationship in a new way.
The fanfiction could explore their relationship by having them communicate in a more in - depth way. Since they are part of Team 7, they are constantly in each other's company. Naruto might start to notice the little things about Hinata, like how she always blushes when he looks at her. Hinata, on the other hand, might become more confident around Naruto because of their Team 7 experiences. There could also be situations where they have to trust each other with their lives, which further cements their relationship.
One possible scenario could be that Naruto leaves due to a misunderstanding with Sasuke. Maybe Sasuke says something harsh about Naruto's skills and Naruto, in his pride, decides to leave. Another could be that Naruto feels he's holding the team back in some way and leaves to train on his own in order to become stronger without being a burden. Or perhaps there's a mission gone wrong where Naruto is blamed for something he didn't do, and he leaves out of a sense of unfairness.
In a lot of Naruhina fanfiction, Naruto is indeed OP. His character has so much potential for being OP given his origin in the Naruto series. He has the Nine - Tails within him, which is an incredibly powerful source of chakra. In fanfiction, authors can take this and run with it. They can make him so strong that he can change the whole ninja world on his own. When it comes to Naruhina fanfiction, his OP nature can also be used to show how he protects Hinata, making their relationship more endearing. For instance, he might be able to take on entire armies to save her, which is a common trope in such fan - made stories.
Sasuke might initially be indifferent on the surface, but deep down he would feel a sense of loss. He has always had a rivalry with Naruto, and Naruto's departure would mean an end to that dynamic. Sakura would be devastated. She has grown to care about Naruto as a friend and teammate, and his leaving would leave a big hole in the team.
