Sakura would be deeply affected. She has been Naruto's friend and teammate for a long time. His departure would make her feel guilty, thinking that she could have done something to prevent it. She might also worry about his safety out there alone.
The village elders would be in a panic. Naruto is a powerful asset to Konoha. His departure means the loss of a strong shinobi. They would also fear that Naruto might use his knowledge and power against Konoha in the future. And the other villagers who have come to rely on Naruto for protection would be left feeling vulnerable.
Kakashi would be worried. He has always been a mentor to Naruto. His departure would make Kakashi feel like he failed in some way. He would probably try to find Naruto to bring him back or at least make sure he's okay. The rest of the Konoha 11 would also be affected. They would miss Naruto's presence and some might even question the village's decision (if there was one) that led to Naruto leaving.
His friends would be worried. Sakura might be very concerned about his safety and feel sad that he left. She may also feel guilty if she thinks she could have done something to prevent his departure.
It could lead to political unrest in Konoha. There might be those who blame the village leadership for Naruto's departure. This could lead to power struggles as different factions try to take control and change the way the village is run. Some might demand more transparency and better treatment of their shinobi to prevent such a thing from happening again.
It could create a sense of unease and fear. Naruto is a very powerful ninja, and if he turns dark and leaves, the villagers would be worried about him coming back as an enemy. It might also lead to a decrease in morale among the ninjas who once considered Naruto a friend or ally.
This type of fanfiction can also affect how new fans perceive the Naruto world. If they stumble upon 'konoha hates naruto' fanfiction first, they might get a very different initial impression of the series compared to those who start with the original story. It can be both a source of new interest, as they might be curious to see how such a different take is developed, or a source of confusion if they are not aware that it is a non - canonical exploration.
It might lead to a decrease in the popularity of yaoi fanfiction within the Naruto fandom. If the general idea that Naruto would hate it spreads, some fans might refrain from creating or consuming such fanfiction out of respect for the character. On the other hand, it could also lead to a backlash from fans who think that fanfiction should be a free - for - all creative space regardless of what the character might think.
There could be a power vacuum. Naruto and Sakura are two of the most powerful ninja in Konoha. Their absence may leave the village vulnerable to attacks from outside forces. Other villages might see this as an opportunity to gain an advantage over Konoha.
Some might be in shock. Naruto, regardless of being male or female in this fanfiction, has been a significant part of the village. People who have come to know her would be surprised that she would leave. They might start to question if there was something they could have done to prevent it.
Sakura would be heartbroken. She has deep feelings for Naruto, and his sudden departure would make her feel abandoned. She might initially be angry at him for leaving without saying goodbye but would soon worry about his safety.
Well, their friends in Konoha would be really sad. For Naruto, his friends like Sakura and Shikamaru would feel betrayed at first. They might not understand why he left without saying much. But later, they might start to suspect that there are deeper reasons and some of them might even try to find out the truth and support Naruto from afar.
