There are many novels that fit this plot. Here are a few that I recommend to you:
1. "Frost Monarch and Mad Concubine: The Loser and Defiant Third Miss."
2. "Defiant Concubine Daughter: The Useless Third Miss"
3. "Blessed Farmer Girl"
4. "Reborn in a Different World: The Loser Missy"
5. [Celestial Battle God]
6. "The loser Concubine Kuang is too arrogant."

It could be someone who is jealous of Naruto's hidden genius. Maybe a fellow ninja who senses that Naruto is hiding something and wants to expose him out of envy. This person might try to undermine Naruto at every turn.
I heard about a girl who was a musical prodigy. In her music class, she could play the piano pieces of famous composers flawlessly after just a few days of practice. Her teacher was in awe of her talent. She had an inborn sense of rhythm and could also compose her own music at a very young age. The teacher provided her with more advanced music sheets to challenge her, and she always rose to the occasion.
I recommend "Holy Demon" to you. This book is about a weak demonic disciple who was mistaken for the son of the demonic path. After being ostracized by others, he finally stepped forward. I hope you like this fairy's recommendation. Muah ~😗
There's also a possibility that their relationship could turn into a more complex, non - romantic one. They could become comrades who respect each other from a distance. Sakura could see Sasuke as a powerful ally for the village, and Sasuke could recognize Sakura's strength and importance. They may not have the close, personal relationship they once had, but they'll work together when necessary for the greater good.
Newly discovered magical families could rise to prominence. These families might have been in hiding or just not known before, but now they play a crucial role in the wizarding world of 1000 years later. Their members could be the main characters, bringing in fresh perspectives and magical abilities that were previously unheard of.
