She might immediately go to comfort him. Hinata has always cared deeply for Naruto, so seeing him cry would likely trigger her protective and empathetic side.
Hinata would probably be extremely shy at first. She might blush furiously and be at a loss for words. After all, she has had a crush on Naruto for a long time, so it would be a dream come true for her.
Hinata might become more confident in herself. After seeing Naruto's memories of his own struggles and how he overcame them, she could apply the same principles to her own life. For example, if she sees how Naruto faced his insecurities about being a jinchuriki, she could face her own insecurities about her skills as a ninja more bravely. This would lead to a more well - rounded and strong Hinata.
Well, in such a fanfic, Naruto seeing Hinata in heaven could be a really emotional moment. It might start with Naruto being confused about where he is and then suddenly spotting Hinata. Their encounter could lead to a heart - to - heart conversation. Maybe they would talk about their past, their dreams, and how they felt about each other all along. It's a great concept for a fanfic as it gives an opportunity to expand on their relationship in a more spiritual and emotional setting.
He could be deeply hurt. Naruto has a big heart, and Hinata has been an important person in his life. Her abandonment might make him question his self - worth. He might go into a bit of a slump, not being as enthusiastic as he usually is. But then, he's Naruto. He'd probably eventually pick himself up and try to figure out a way to either get her back or move on with his life in a positive way. He might also wonder if there's some greater danger or threat that he needs to deal with that caused Hinata to leave.
One possible plot could be that Hinata accidentally stumbles upon Naruto's memories during a mission. Maybe they are in a strange place where memories are made visible, and Hinata starts to understand Naruto on a much deeper level. She sees his lonely childhood, his determination to be recognized, and his dreams for the future. This newfound understanding could strengthen their relationship and make Hinata more determined to support Naruto in his goals.
Well, in some fanfictions, when Naruto sees Hinata in the waterfall setting, it could be a moment of sudden realization. He might finally notice her in a new light, perhaps seeing her beauty and the depth of her feelings for him more clearly. It could be a turning point where he starts to develop deeper romantic feelings for her.
Hinata would probably be angry too. She might be angry at the circumstances that led to Naruto's death, whether it was an enemy or some other misfortune. She could direct her anger towards training harder, vowing to become stronger so that she can prevent such a tragedy from happening to others in the future.
He would be filled with a deep sense of grief. Naruto has always cared about Hinata, and her death would be like a part of him has been ripped away. He might isolate himself for a while, blaming himself for not being able to protect her. But eventually, he would use his pain as motivation to get stronger and fight against whatever caused her death.
Hinata might react with anger. She's a strong - willed character deep down. So she could confront the person who cheated on her head - on. She might yell and express her disappointment and hurt. This would show her growth from a shy girl to someone who stands up for herself.
The weather could pose a challenge. If they go to a place with unpredictable weather, like a mountain area, they might get caught in a storm. Naruto would try to protect Hinata from the elements, but they could end up lost or having to find shelter in a less - than - ideal place. Also, adjusting to living together in such a close and new way could be difficult for both of them.
