I'm not sure if it's extremely popular. It's a very niche concept within the Naruto fanfiction world. There are so many different types of fanfiction out there, and while some people might be interested in exploring this particular dynamic between Naruto and Sasuke, it's not as mainstream as, say, just general Naruto adventure or Naruto - Sakura romance fanfiction.
Well, 'cuck' is a term often used in certain fanfiction contexts which implies a rather unfaithful or humiliating situation. In 'naruto cucks sasuke fanfiction', it might be about Naruto being in a situation where he somehow gets the upper hand over Sasuke in a relationship - like in a romantic or competitive sense. But it really depends on how the author of the fanfiction interprets and writes it.
Probably not. There are thousands of Naruto fanfics out there, and this one with such a specific and rather odd - sounding title doesn't seem to be among the popular ones. The use of the term 'cucks' which is a bit of an edgy and not so common term in fanfic titles, along with 'lemon' which is also not for the general audience all the time, makes it less likely to be popular.
I'm not sure as I haven't read this specific fanfic. But generally, in a fanfic with such a title, it might involve some sort of relationship drama among the characters Naruto, Kizashi, and perhaps some 'lemon' elements which usually imply romantic or spicy situations. However, this is just speculation.
Yes, there might be such fanfics out there. In the Naruto fandom, with a large number of fans creating various types of stories, it's possible that some would write a story where Naruto destroys Sasuke in a way that could be seen as Sasuke - bashing. However, these kinds of fanfics may not be in line with the overall spirit of the original work which focuses on their complex relationship and growth.
In the 'naruto is protected by sasuke fanfiction', Sasuke's protection of Naruto could be multi - faceted. Sasuke, being a powerful ninja, would first of all use his physical strength and speed to block attacks aimed at Naruto. Emotionally, his bond with Naruto would make him extremely vigilant. He might sense Naruto's distress from afar and rush to his aid. In terms of strategy, Sasuke would likely plan their movements carefully when they are in dangerous situations, ensuring Naruto is always in a relatively safe position. His ability to quickly analyze a battle situation and react accordingly would be crucial in protecting Naruto.
Well, in some fanfictions, Naruto might be promoted over Sasuke because Naruto has always been seen as the more positive and inspiring character. He has a strong will to protect his friends and the village, and his growth throughout the series is more in line with the traditional hero's journey. His ability to make friends and bring people together could be a reason for his promotion in the fanfiction.
In proper fanfics rather than 'lemon' ones (as 'lemon' implies inappropriate content), Naruto is known for his never - give - up attitude. He's the heart of the story, always trying to bring Sasuke back and protect his friends. Sasuke is a complex character, with his family's past haunting him, which makes him seek power and revenge at times. Sakura, she starts as a girl with a crush but evolves into a capable ninja. These characteristics are often the foundation for fanfic authors to create interesting stories that don't involve improper content.
It might be for Naruto's own good. Sasuke may believe that Naruto is on a dangerous path that will lead to his downfall. So he captures him to keep him from making bad decisions, like sacrificing himself for the village or something similar. He wants to save Naruto from himself in a sense.
In some fanfictions, Naruto might reject Sasuke because of Sasuke's continuous pursuit of power in a way that endangers others. Naruto, who values friendship and the safety of the village, could see this as a betrayal of their shared values.
