Yes, there are quite a few. Some fanfiction writers have explored this rather unique relationship in creative ways. They often build on the deep bond Kakashi and Naruto share in the original series and develop it into a romantic one with interesting plotlines and character developments.
Kakashi could be initially shocked. He might not have expected Naruto to have such feelings towards him. But being Kakashi, he would probably handle it in a calm and collected manner.
Well, there could be. Fanfiction writers love to explore unique and unexpected relationships. Since Naruto and Kakashi are both popular characters in the Naruto universe, some writers might come up with such a plot for the sake of creativity and exploring different storylines. But it's not a part of the official Naruto story.
Definitely not. In the Naruto universe, Kakashi is one of Sakura's superiors in a sense, as he is an experienced ninja and part of her training regime. Sakura's heart has always been set on Sasuke, from her childhood crush to her more complex feelings for him as they grow older. There's no indication of any romantic connection between Sakura and Kakashi.
Sasuke could be a popular character. He might be involved in the story in a way that either helps or hinders the situation where Naruto hurts Kakashi. For example, if Sasuke tries to stop Naruto from doing something stupid that would hurt Kakashi.
Another reason could be related to Kakashi's past actions. If there are some secrets or things Kakashi did in the past that come to light and Naruto doesn't like them, he could snap at Kakashi. Naruto has a strong sense of justice and loyalty, so if he feels betrayed or misled by Kakashi, his reaction could be to snap.
One popular theme is the mentorship evolving into a deeper emotional bond. Kakashi being Naruto's teacher, the fanfictions often explore how their relationship grows beyond that. Another theme could be them facing difficult missions together and the trust they build during those times.
Kakashi might be initially surprised. But then, he would probably use it as a teaching moment for Naruto. He could say something like 'Naruto, stealing is not the way of a ninja.' And then give him a punishment like extra training.
There are several places. Firstly, Archive of Our Own is known for its extensive and diverse range of fanfictions. The tagging system there makes it easy to find what you're looking for. Fanfiction.net is also a classic destination. Additionally, some Naruto fan forums might have sections dedicated to fanfiction sharing. These forums often have a community of dedicated fans who write and share their own stories. You might need to register on some of these platforms to access all the content, but it's usually worth it if you're interested in finding this specific type of fanfiction.
One possible reason could be that Kakashi is preoccupied with other important matters in the village. Maybe he has some top - secret missions or tasks assigned by the Hokage that demand his full attention, leaving him with little time to focus on Naruto.
