In this fanfiction, it could also be that Sakura has misinterpreted some of Naruto's actions as signs of romantic interest. For example, Naruto might have been just being friendly and supportive, but Sakura took it as something more. As a result, she tells her friends that she's dating Naruto. Her friends could be either supportive or skeptical. If they're skeptical, they might try to make Sakura see the truth, which would add more conflict to the story.
Well, in such a fanfiction, there could be a lot of drama. Maybe Sakura starts acting really love - struck towards Naruto, while Naruto is completely oblivious at first. This could lead to some really comical misunderstandings, like Sakura bringing Naruto lunch every day thinking it's a couple - thing, but Naruto just thinks it's a friendly gesture.
One plot idea could be that Sakura and Naruto are assigned on a mission together. During the mission, Sakura keeps dropping hints about their 'relationship' which confuses Naruto. Eventually, Naruto realizes what Sakura thinks and he has to gently let her down, but this causes Sakura to be heartbroken and she becomes less effective in the mission.
One possibility is that Naruto is initially confused by Sakura's assumption. He might be so focused on his goals, like becoming Hokage, that he hasn't really considered a romantic relationship with Sakura in that way. He could gently let her down, explaining that he values her as a friend and teammate but doesn't have those romantic feelings. This could lead to a bit of an awkward phase in their relationship, but they would likely work through it and return to their strong friendship.
If in the fanfiction everyone believes Naruto is dead, it would have a huge impact. Firstly, the balance of power in the ninja world would shift. Allies of Konoha might feel less secure. Secondly, the emotional toll on his loved ones would be immense. Hinata would be devastated, and she might struggle to raise Boruto alone. Thirdly, the story could take a turn where Naruto is actually alive but in a different dimension or held captive, and the fanfiction could then focus on the journey to bring him back.
In such a fanfiction, it could be a scenario where Sakura has been training intensively and has developed new skills. Maybe Naruto underestimates her, and she takes him by surprise in a sparring match or a fight during a mission. It might also be a plot device to show Sakura's growth and independence from the typical dynamic where Naruto is often the stronger one.
She could take a pregnancy test. If it's positive, it would start a whole new chapter of her life. She'd have to tell Vegeta, and his reaction could be anything from shock to joy. If it's negative, she might be relieved or disappointed, depending on her true feelings about having a child at that moment.
Well, if Naruto thinks he's the Kyuubi in a fanfic, he would probably start to exhibit more of the Kyuubi's traits. He might become more aggressive and less patient. His appearance could also change, maybe having some Kyuubi - like features all the time. And his training would take a whole new turn, as he'd be trying to master the power he believes is his own, which is really the Kyuubi's.
Well, in such a fanfiction, Naruto in Sakura's body would probably be shocked by how different it is. He might accidentally let out his Naruto - like enthusiasm during Sakura's quiet study time or something. And when it comes to fighting, he'd have to figure out how to use Sakura's skills effectively. Sakura in Naruto's body could be a force to be reckoned with. She could train even harder, as she now has Naruto's stamina. And she might use Naruto's popularity to her advantage to promote some of her own ideas within the village.
In a fanfic, if Naruto punched Sakura, it could be due to a major misunderstanding. Maybe Sakura was being controlled by an enemy's jutsu and Naruto, in his haste to stop her from doing something dangerous, resorted to physical force. This would create a huge rift in their relationship, and Sasuke might get involved to either side with Naruto or defend Sakura.
One possibility is that Naruto could be initially shocked but then gradually reciprocate her feelings. This would lead to a new power couple in the fanfiction world of Naruto. They could go on missions together with a new level of closeness and understanding.
Well, it could lead to her becoming much stronger and more confident. Maybe she'd master new skills and be able to handle tougher challenges.
