Well, one characteristic is a strong focus on character development. For example, showing how Naruto and Hinata grow both individually and in their relationship. They should be in - character, with Naruto's determination and Hinata's shy yet strong - willed nature intact. Another aspect is a good plot. It could be about them facing challenges in the ninja world together, like fighting a new enemy or dealing with political issues in the village. Also, the writing style should be engaging, making the readers feel the emotions of the characters, whether it's the excitement of a battle or the warmth of their growing bond.
A key characteristic is authenticity. The fanfiction should stay true to the essence of the Naruto series. The values that Naruto represents, such as never giving up and believing in oneself, should be reflected. For Hinata, her loyalty and her growth from a shy girl to a confident woman should be well - portrayed. The story should also have a proper pacing. Not too rushed so that the relationship seems forced, nor too slow that it becomes boring. And it should be inclusive of other characters from the series as well, because Naruto and Hinata don't exist in a vacuum. Their relationship is also influenced by their friends, family, and the village as a whole.
Good non - lemon Naruto Hinata fanfiction often has a detailed world - building aspect. Since it's set in the Naruto universe, it should expand on the existing world. Maybe introduce new ninja techniques related to their clans or explore different parts of the Hidden Leaf Village. The relationship between Naruto and Hinata should be developed gradually. It's not just about them suddenly falling in love, but rather through shared experiences, like going on missions together, or helping each other out in times of need. And the story should have a positive message, like the power of love and friendship in a world full of chaos and danger.
