I'm not sure specifically as there could be many different interpretations of such a fanfic. It might be about Naruto finally dropping a false facade he's been maintaining throughout the story, perhaps related to his strength, his relationships, or his goals.
Well, it could be that in this fanfic, Naruto stops pretending to be okay with certain situations in the Naruto universe. For example, he might stop pretending that he doesn't have doubts about the Leaf Village's leadership or that he's fully on board with all the ninja traditions. Maybe he starts to question things more openly and this causes a stir among the other characters. It could lead to new alliances, conflicts, or a whole new direction for his character development.

Perhaps in this 'percy stops pretending fanfiction', Percy has been living a lie in the fanfiction realm. It might be that the writer wants to take the story in a new direction by having Percy be more true to himself. This could lead to all sorts of new interactions with other characters and new plot twists.
One possible reason could be that the author wants to focus on other characters. Maybe they feel that Naruto's story has been told enough in the fanfic and it's time to give other characters the spotlight.
One possible reason could be that Naruto has faced too many betrayals. Maybe his friends turned on him in the fanfic, which made him lose faith and stop caring.
It could be that Naruto has outgrown his initial feelings. As he matures, he starts to view Sakura more as a friend. In the fanfic, his experiences in the ninja world might have changed his perspective on love. He might have seen so much pain and sacrifice that he no longer wants to hold on to a love that might be one - sided or not as fulfilling as he once thought. Also, Sakura's continued love for Sasuke in the fanfic could be a factor that makes Naruto step back.
Sure. If Percy stops pretending in the fanfiction, it's a big step in his character development. He's likely moving from a state of falsehood to authenticity. This can make him more relatable to the readers as he becomes a more 'real' character within the fictional world.
In the fanfic, it might be that Naruto has new responsibilities in the village that are more important than chasing Sasuke. For example, he could be needed to deal with new threats to Konoha, so he has to let go of his personal mission to bring Sasuke back.
The story would likely become less comical if Naruto stops acting. His acting often adds a humorous element to the fanfic. Without it, the mood could shift to be more serious.
He might become more withdrawn. Instead of being the energetic and enthusiastic Naruto we know, he could start to isolate himself from others.
One possible reason could be that the fanfiction author wants to focus on other characters. Maybe they feel they've explored Naruto's character enough and want to give more spotlight to characters like Sasuke or Sakura. Another reason might be that the plot of the fanfiction takes a turn where Naruto's acting skills are no longer relevant or needed.
