One possible reason could be that Naruto is extremely powerful and his skills are needed to protect Konoha from a new and powerful threat. His combat abilities, like his Rasengan and Sage Mode, are crucial for the village's defense.
Sakura could be one of the main characters. She has a long - standing relationship with Naruto and might play a role in convincing him to return. Maybe she tells him about the state of the village's hospital or how his friends miss him.
It could be the village elders. They often make decisions for the benefit of the village as they see it. They might think Naruto is needed back in Konoha to deal with potential threats or to boost the morale of the villagers.
One possible reason could be that they need his power. Naruto is extremely powerful, and Konoha might be facing a new threat that they believe only Naruto can help deal with. For example, a powerful enemy from outside the village might be on the verge of attacking, and Naruto's combat skills and unique jutsu are crucial for the village's defense.
Their return would likely have a huge impact on Naruto. He would finally have the family he always longed for. He might become more confident and less of an outcast as having parents is a normal thing in Konoha. He could also learn more about his family's history and jutsu directly from them.
Naruto might initially be resistant. He could feel that Konoha is trying to control him again, just like in the past when he was often shunned. If he has found a new life or purpose outside of Konoha, he might not want to give it up easily.
One possible reason could be a new threat to Konoha that only Naruto has the power to face. For example, a powerful enemy has emerged and the village elders believe Naruto's strength is essential for the village's defense.
Well, one possible plot could be that Naruto is on a very important mission far from Konoha. But due to some political reasons, like the village elders fearing he might defect or get influenced by outside forces, they force him to return. For example, they might spread false rumors about him being in danger or that he's needed urgently for some made - up security reason.
In this fanfiction, the reception could be mixed. On one hand, the older generation who remembered Minato and Kushina would be very glad to see them return. They were important figures in Konoha's history. But on the other hand, some of the younger shinobi who didn't know them might be a bit cautious at first. Still, once they learn about their heroic deeds, they would likely warm up to them.
A new character could be introduced as the main antagonist. Maybe a powerful ninja from another village who has infiltrated Konoha's politics. This character could be the one behind the idea of forcing Naruto back, with the intention of using Naruto as a pawn in a larger scheme against Konoha.
