One idea could be that Naruto somehow gets trapped in a dimension where Kaguya has become a yandere for him. She tries to keep him there all to herself, while Naruto has to figure out a way to escape and also deal with her obsessive behavior.
Not all texting stories are free. Some are, but many come with costs like ads or limited access without paying. You need to check the specific app or website to know for sure.
One common theme is possessiveness. Since Naruto is in a yandere state, he is extremely possessive of Sakura. Another theme is the distortion of love. His love for Sakura is not the normal kind but rather a bit extreme and obsessive.
Start with a strong inciting incident. For example, Kaguya could be resurrected with a yandere - like obsession for Naruto due to some dark magic. Then, build up the conflict as Naruto tries to resist her advances while also dealing with the chaos she causes in the ninja world.
A girl I knew got a text from her ex - boyfriend who had passed away a year before. The text just said 'I miss you'. She thought it was some cruel prank at first. But then more texts came. 'Why did you forget me?' She was really scared. She showed the texts to her family, but they thought she was making it up. She changed her number in the end, but she still wonders if it was really her ex - boyfriend somehow reaching out from the other side.
You can start a texting story by introducing the main character and their situation. For example, 'John was sitting in a boring meeting when his phone buzzed. He saw a text from an unknown number.'
One common theme is possessiveness. Since Hinata is a yandere in these fanfics, she is extremely possessive of Naruto. She doesn't want to share him with anyone else, whether it's his friends or other potential love interests.
In such a fanfiction, the plot might involve Konan being overly possessive of Naruto. She could isolate him from others in the Hidden Leaf Village, seeing them as threats to her relationship with Naruto. Konan might train Naruto in her own unique ways, which could be a blend of her own combat skills and some of the techniques she learned from Pain. This would make Naruto a very different kind of ninja compared to the original story, with a more secretive and perhaps darker edge to his abilities.
His character development would be quite different. Since Konan is yandere, Naruto would grow up in an environment where he is constantly being sheltered. He may not have the same sense of self - confidence that he has in the original story. Instead, he'd be more reliant on Konan. His understanding of relationships would also be skewed. He might see Konan's possessiveness as normal and have difficulty forming healthy relationships with others later on. His ninja skills would be a mix of Konan's origami - based jutsu and his own Uzumaki heritage, but his overall attitude towards being a ninja would be less about the village and more about pleasing Konan.
