His relationship with other female characters might change too. For example, if Ino is still interested in Sasuke and sees Kakashi being so obsessed with Sakura, she might view Kakashi as an obstacle. Also, his fellow ninja teachers might be concerned about his behavior and how it affects the overall team dynamic, which could lead to some confrontations or at least some awkward conversations.
It could make his relationship with Naruto tense. Naruto might notice Kakashi's special attention to Sakura and feel jealous or confused. After all, Naruto also cares a great deal about Sakura. And with Sasuke, Kakashi's obsession could make Sasuke distrust him more, as Sasuke is also connected to Sakura in his own way.
Regarding the relationship with other characters, Kakashi's overprotectiveness of Sakura can strain relationships. For example, the other ninja in the village may think Kakashi is playing favorites, which could lead to resentment among some. With their own teammates, it can be a bit of a mess. Naruto might try to understand at first but as time goes on, he may get frustrated that Kakashi seems to be only concerned with Sakura's safety. Sasuke may view it as a sign that Sakura is not as strong as she claims and this could further damage their already complex relationship.
Well, their argument could make Sasuke more distant. Sasuke already has his own issues and if Naruto and Sakura are arguing, it might seem like chaos to him. He might withdraw further, thinking that his friends can't even get along. For Kakashi, it could be a headache. He has to deal with his team's internal conflicts, and an argument between Naruto and Sakura would mean he has to step in and try to resolve it, which could be time - consuming and affect his other duties.
It could make Naruto closer to characters like Shikamaru. Since he's tired of Sakura, he might start spending more time with those who understand him better, like Shikamaru who is smart and can offer different perspectives. With Sasuke, it might create an even more complex dynamic. Naruto might be less likely to try and bring Sakura and Sasuke together if he's tired of her.
It could strengthen their bond. By being interested in fanfiction about Naruto, Minato shows that he's deeply invested in Naruto's story, which Naruto might appreciate.
For Tomoyo, she might be overjoyed as she has always been supportive of their relationship. She could see this kiss as a sign of their relationship deepening and might start planning more things for them, like new outfits for their future 'dates' in card - capturing adventures.
For the new generation of ninja like Boruto and his friends, they might view Sakura's overprotectiveness as strange. Boruto in particular, who has his own views on Naruto, might not understand why Sakura is so over the top in protecting Naruto. This could lead to some misunderstandings between the generations.
It might also affect how their friends view their relationship. If Naruto snaps at Sakura in front of others, their friends might try to mediate or take sides. This could further complicate their relationship as they have to deal with not only their own feelings but also the opinions of their friends.
Naruto's decision could potentially strain his relationship with Sakura herself at first. She might be used to Naruto's pursuit and his sudden giving up could make her feel a bit lost or even angry. However, in the long run, it could also lead to a more honest and healthy friendship between them as they both learn to respect each other's boundaries and feelings more clearly.
In this fanfiction scenario, Kakashi's failure might cause Sasuke to be more reckless. Sasuke, feeling let down, could go off on his own more often. Sakura, who might have relied on Kakashi to keep Sasuke in check, would then be left to try and deal with Sasuke on her own. This could put a lot of stress on their relationship. She might be more desperate to bring Sasuke back to the right path, but Sasuke could see her as being too pushy, all because of Kakashi's initial failure.
With his friends, it could be a mixed bag. Some friends might support him wholeheartedly, which could strengthen their bond. However, others may be cautious. For instance, if a friend has a close relationship with a particular god, Percy's hatred could cause tension. Also, his attitude towards the gods might make it difficult for him to interact with godly allies or enemies. He may be more hostile towards them than necessary, which could change the dynamics of battles or negotiations.
