Another way is through jealousy. If Sasuke gets more attention or power in the fanfic world, and he flaunts it in a way that makes Naruto feel inferior, it's a form of emotional harm. Naruto, who has always worked hard and dreamed of being recognized, would be deeply hurt by Sasuke's disregard for his feelings in such a situation.
Sasuke could also emotionally hurt Naruto by choosing a path that goes against everything Naruto stands for. If Sasuke allies himself with the wrong people or starts to embrace dark ideologies, Naruto feels betrayed. This is like a stab in the heart for Naruto, who has always believed in Sasuke's goodness and their shared values.
In some fanfics, Sasuke might reject Naruto's attempts at friendship harshly. He could say cruel things about Naruto not understanding his pain or goals, which deeply wounds Naruto. For example, Sasuke might tell Naruto that he's always been a nuisance and that he never wanted their friendship, making Naruto question his self - worth.
Writers often use misunderstandings. For example, Naruto might misinterpret Boruto's actions as being rebellious when Boruto is actually trying to prove himself. This leads to Naruto scolding Boruto harshly, which hurts Boruto deeply as he feels his father doesn't understand him. It's a simple yet effective way to show emotional hurt.
Writers often depict Naruto as a very protective figure towards baby Sasuke. He might be like an older brother, always making sure Sasuke is safe and has enough to eat.
Fanfiction writers could use power imbalances. If Naruto has suddenly gained a lot of power and doesn't fully control it, he could accidentally hurt Sasuke. It shows the consequences of power and the need for control in their relationship.
They add more depth to the relationship between Naruto and Sasuke. By exploring different scenarios and emotions, they allow fans to see new aspects of their bond.
Well, often the relationship is one of mutual respect. The daughter respects her parents' skills and experiences. Sasuke may pass on his combat techniques and knowledge of the Uchiha clan to her. Sakura would be there to support her emotionally and also teach her medical ninjutsu if she's interested. The daughter might also have some rebellious moments as she tries to find her own path while still loving and being loved by her parents.
Writers often show female Naruto becoming more nurturing. She's always been strong -willed, but now she has a new side as she's going to be a mother. Sasuke, on the other hand, may start to open up more emotionally. He might share his fears and hopes for the future with female Naruto more than he ever did before.
At first, Naruto is probably shocked and confused. He might not understand why the village would take such a harsh step just for hurting Sasuke. He may feel betrayed, especially if he thought he had friends and allies in the village.
Fanfictions often depict Sakura's growth in relation to Sasuke by highlighting her emotional maturity. At first, she was a girl with a simple crush on Sasuke. But as the story progresses in fanfictions, she starts to understand Sasuke on a deeper level. She realizes his pain and his reasons for his actions. This understanding makes her more empathetic and also helps her grow as a person. She becomes less clingy and more of an equal partner to Sasuke, which is a huge growth from her initial character in the series.
Often, they start by setting up a relationship between Naruto and Sasuke that the readers are familiar with from the original series. Then, Sasuke's act of cheating is introduced, which usually leads to a lot of drama. Naruto might be shown as heartbroken, and the story could then explore how he copes with it.
In certain fanfics, Kushina's death is seen as a great loss to the Uzumaki clan. Since she was one of the last prominent Uzumaki members, her death could lead to the decline of the clan's influence even further. And Naruto, being her son and a hero, his death could cause a sense of despair among the younger generation who looked up to him as a symbol of hope.
