In some fanfictions, it changes their relationship dramatically. Naruto, being a bit clueless at first, might start to have dreams about Hinata after the accidental kiss. This could lead to him being more protective of her. Hinata, on the other hand, might be super embarrassed but also secretly happy. Their friends might notice the change in their dynamic too, and start teasing them or trying to push them together.
Often, this accidental kiss is a turning point. It could make Naruto question his feelings towards Hinata. He might start noticing little things about her that he didn't before, like the way she blushes or how she's always there for him. For Hinata, it gives her a glimmer of hope that Naruto could actually return her feelings. This event can set off a chain of events where they gradually grow closer, with more shared moments and deeper conversations.
There could be a scenario where Naruto doesn't really understand the significance of the kiss at first. But Hinata is deeply affected and starts avoiding Naruto. This makes Naruto wonder what he did wrong and he tries to find out. As he tries to figure things out, he starts to realize his own feelings for Hinata might be more than just friendship. In some fanfictions, this also might attract the attention of other characters who have an interest in either Naruto or Hinata, causing some jealousy and drama.

In this kind of fanfiction, Hinata's care often deepens their bond. Naruto, who has always been somewhat alone, starts to rely on Hinata more. This reliance can turn into a deeper form of love. As Hinata takes care of his physical and emotional needs, Naruto realizes how important she is to him, which can lead to a more romantic relationship between them.
Their relationship would likely become even stronger. As Hanyou, they would be going through a very unique and difficult experience together.

Naruto would be more protective of Hinata, and Hinata would be more confident in standing by Naruto's side, knowing they are both in this strange new state together.
The training by Kaguya could strengthen their relationship. They would be sharing a unique experience, facing the challenges of Kaguya's training together. This would likely create a deeper bond between them as they support and encourage each other through the difficult training.
Their relationship could become stronger. If Hinata sees a future where they are together and happy, it might give her more confidence in their relationship in the present. She could be more open with Naruto about her feelings.

Naruto would be even more protective of Hinata, and Hinata would be a source of comfort for Naruto. They would have to communicate and trust each other more deeply to survive in Orochimaru's lair.
