It could symbolize a new chapter in their relationship. Before, Naruto was mostly focused on his goals and being recognized in the village. But after facing Pain, he might have a new perspective on life and love. The kiss with Hinata could be the start of a deeper, more romantic connection, showing that he's ready to explore his feelings for her and let someone be close to him in a different way.
It could be a really sweet fanfic. Naruto and Hinata have a long - standing relationship in the Naruto series. Their kiss in a fanfic might happen after a big battle where they realize their deep feelings for each other. Maybe Naruto finally sees Hinata in a new light and can't resist kissing her, and it could be a moment filled with passion and love.
One possible plot could be that Hinata and Naruto start to train together more intensively. After facing Pain, Naruto realizes Hinata's feelings for him more deeply. They could go on missions side by side, and Hinata becomes stronger under Naruto's influence. Naruto, in turn, starts to see Hinata as not just a friend but someone he could potentially have a future with.
In such a fanfic, it might explore the emotional turmoil. Pain's attacks on the village would not only be a physical threat but also an emotional one. Hinata could be in a position where she has to choose between her love for Naruto and her duty to the village. Naruto, on the other hand, would be dealing with his own feelings for Hinata while trying to defeat Pain. And Pain himself could be presented with more complex motives, perhaps having some sort of connection to Naruto's past that is revealed during the battle.
There are probably some. Fanfic writers often explore the relationship between Naruto and Hinata in different ways. They might write about their first kiss, or a romantic moment where a kiss occurs. However, the quality and content can vary greatly among different fanfics.
One possible plot twist could be that Hinata is kissing someone as part of a mission. Maybe she has to pretend to be in love with a character to gain information. Naruto, seeing this, initially misunderstands but then later discovers the truth and respects Hinata's dedication to the mission.
Here's how a fanfic might go. After the battle with Pain, Naruto is surrounded by people, but his eyes keep searching for Hinata. When he finally spots her, he makes his way through the crowd. Hinata is blushing but stands her ground. Naruto reaches her and says, 'Thank you for always being there for me.' Then, he cups her face and kisses her. This kiss is a culmination of all the times Hinata has supported Naruto, and now he's finally realizing his own feelings for her.
Maybe Orochimaru's former followers who are still lurking in the shadows. They see Naruto as a threat and Hinata as an easy target to get to Naruto. Another possibility could be some power - hungry shinobi from other villages who view Konoha as weak after the Pain incident. They might target Naruto and Hinata as key figures in Konoha's future to try and undermine the village's rebuilding efforts.
Well, it's possible that Hinata becomes more confident around Naruto after the Pain Invasion. She might be more forward in expressing her emotions, which could lead to Naruto reciprocating her feelings. Maybe they go on adventures together in the village, helping people out and in the process, their bond grows stronger. They could also have some really deep conversations about their pasts, their dreams, and how they see the future of the village, which further cements their relationship.
One possible plot is that Pain targets Hinata to get to Naruto. Since Hinata has a special place in Naruto's heart, Pain might think that by hurting her, he can break Naruto. But Hinata shows great courage and Naruto comes to her rescue.
It could symbolize protection. Naruto is a strong character, and by kissing Sakura's forehead, he's sort of pledging to keep her safe. It's like a knight protecting his lady in a way, but in the Naruto universe context.
