One possible reason could be a major ideological difference that has grown over time. Maybe Sasuke has adopted a more extreme view on protecting the village or avenging his clan that Naruto can't support. Another reason might be a misunderstanding that has festered. For example, if Sasuke was misinformed about Naruto's actions and intentions and has cut off ties because of it.
One possible plotline could be about the character's journey to rediscover their lost emotions. Maybe they start to open up after a series of encounters with different people in a small town.
Perhaps after facing too much betrayal from the village he loves. If the villagers turned on him despite all his efforts to protect them, it might lead him to close his heart in self - defense, not wanting to be hurt again. He's always tried so hard to gain their acceptance and if that was all for naught, it would be a huge blow.
One possible reason could be that he has become jaded after facing so many hardships in his life. He might have seen too much pain and loss, which has made him numb and less caring in the fictional scenarios of fanfiction.
One possible theme could be redemption. If a character has a 'demon in his heart', they might strive to overcome it and find redemption. Another theme could be self - discovery. As the character battles their inner 'demon', they may learn more about themselves.
Another theme could be the end of something traditional, like the end of the traditional novel format as we know it. It could be an experimental piece that challenges the norms of writing and storytelling. The 'no longer a novel' part might suggest that it combines different literary forms, such as poetry and prose, to create a new kind of literary experience.
In fanfiction, it might be a result of a curse or some dark magic. For example, a villain could have cast a spell on him that weakened his heart both physically and emotionally.
Another theme could be isolation. When a character lives behind a mask, they are often alone in their deception. This fanfiction might show how that character struggles with loneliness, like not being able to truly connect with others because of the false facade they present.
