There could be a fanfic where Naruto has to go on a long - distance mission. Hinata is worried about him. Right before he leaves, she runs up to him and hands him a handmade charm for good luck. Naruto is touched. He pulls her into an embrace and then kisses her gently on the lips, marking their first kiss. It's a bittersweet moment as he then has to leave on his mission.
In a fanfic, perhaps after the war, Naruto is feeling a bit lost. Hinata is always there by his side, supporting him. One day, they are sitting on the Hokage Rock, looking at the village. Naruto starts to talk about his dreams for the future and how much Hinata means to him. Without thinking too much, he just turns to her and plants a gentle kiss on her lips, which is their first kiss.
Some fanfictions might have the first kiss happen in a more unexpected situation. For instance, Hinata gets injured while protecting Naruto, and when she wakes up, Naruto is so relieved and grateful that he impulsively kisses her. This not only shows his deep care for her but also how their relationship can be spurred on by intense emotions and life - threatening situations.
One possible plot could be that Naruto and Hinata are on a mission together. During the mission, they face a difficult obstacle that they can only overcome by relying on each other completely. After they succeed, the adrenaline and the new - found trust lead to a spontaneous first kiss.
It deepens their bond immediately. Their first kiss is like a confirmation of their feelings. After that, they become more aware of each other's presence and start to rely on each other more in both emotional and practical ways.
It might occur when Naruto is training hard and gets injured. Hinata comes to his aid, tending to his wounds. As Naruto looks at her with gratitude, he realizes his true feelings for her. Hinata, seeing the look in his eyes, blushes deeply. Then, slowly, they share their first kiss, a tender moment filled with unspoken love.
One of the popular ones is 'A Moment of Bliss' which beautifully portrays the relationship between Naruto and Hinata leading up to their kiss. It really captures their emotions well.
One key element is the build - up of their relationship. It has to show how Hinata's love for Naruto has developed over time and how Naruto starts to reciprocate. Another is the setting. A beautiful or meaningful place for the kiss, like the Hidden Leaf Village rooftops. Also, the emotions involved. Their nervousness, excitement, and deep affection should be well - portrayed.
