One reason could be Naruto's recklessness. In fanfiction, Naruto might do something extremely dangerous without thinking, and Sakura, being worried about his safety, yells at him. For example, if he decides to take on a powerful enemy alone without a proper plan.
In the fanfiction, Naruto's parents yelling at Sakura could be a turning point. It could make Sakura question her place in Naruto's life. For example, she might think that she is not good enough for Naruto or that his family will never accept her. On the other hand, it could also make Naruto realize how important Sakura is to him and he might stand up to his parents to defend her, which would show a new side of their relationship.
There could be a fanfic with this title, but the use of 'lemon' makes it a bit suspect. In the world of fanfiction, there are so many different takes on Naruto and Hinata's relationship. But if it's a 'lemon' fanfic, it's likely to contain adult - themed content. So, if you're looking for proper, non - inappropriate fanfics about them, you should look for ones that are rated for general audiences.
It might create a rift between them. If Naruto feels that Sakura is always nagging and yelling, he could start to avoid her. In some fanfictions, this could lead to a period of estrangement where they don't work well together as a team. For example, Naruto might choose to go on solo missions instead.
Sakura could be a common character. Since she has a history with Naruto, she might be part of the harem in some fanfictions. Also, Tenten could be included as she is another female ninja in the Naruto universe. And Ino, with her strong personality, could also be written into the harem scenario.
For Naruto, you can show his more romantic and sensitive side. He could be more attentive to Hinata's feelings and needs. For example, he might bring her flowers just because. Hinata can be developed by showing her becoming more confident in the relationship. She could start to initiate dates or activities.
One reason could be envy. Maybe Naruto sees Hinata as having something he doesn't, like a more stable family situation, and he lashes out in jealousy. Another reason might be that he's just being a typical, rambunctious kid who doesn't realize the impact of his words or actions on Hinata.
One great 'Naruto loves Hinata' fanfic is 'A New Beginning'. In this fanfic, it shows Naruto realizing his true feelings for Hinata after the war. It beautifully portrays their relationship development, from Naruto's initial confusion to his deep and abiding love for Hinata. Another one is 'The Road to Forever'. Here, the author takes a different approach, exploring how Hinata's long - held love for Naruto changes and grows as they face new challenges together in the post - war shinobi world.
Hinata supports Naruto by being his emotional anchor. When facing the Juubi, Naruto can get caught up in the chaos and danger, but Hinata is there to remind him of his humanity and the things he's fighting for. For example, with a simple look or a kind word, she can calm him down in the heat of battle.
