On the other hand, Fugaku could also be a very loving father in fanfiction. He might spend a lot of time just holding baby Sasuke, looking into his eyes, and thinking about how much potential his son has. He could be very gentle when Sasuke is fussy or crying, trying to soothe him in a very tender way.
Perhaps in the fanfiction, Fugaku was teaching baby Sasuke about their family's heritage. He could have told Sasuke stories about the great Uchiha warriors, their Sharingan abilities, and the importance of loyalty to the clan. This would not only bond them but also plant the seeds of pride in Sasuke for his family, which would later influence his character development.
There could be moments of frustration for Naruto, especially when Sasuke is fussy or won't do what Naruto wants him to. But Naruto's love for Sasuke would override that. Emotionally, Naruto would be pouring all his love into taking care of Sasuke, trying to give him the family he never had. And Sasuke, even as a baby, might show signs of his future strong - willed self, which could both amuse and challenge Naruto.
Since 'lemon' fanfiction often contains inappropriate content, let's consider general Sasuke and Fugaku fanfiction. There might be stories that delve into Fugaku's perspective of Sasuke's potential. Maybe Fugaku could see the great power within Sasuke early on and has high hopes for him. This could be a story of a father - son relationship full of pride, expectation, and some misunderstandings as Sasuke grows up.
One way to develop their relationship is through a series of difficult conversations. Given their different backgrounds and the history between the Uzumaki and Uchiha clans, there are bound to be misunderstandings. By having honest conversations about things like the Uchiha massacre, Naruto's status as an orphan, and Fugaku's role in the Uchiha clan, they can start to break down barriers. Additionally, if there are situations where Naruto has to protect Fugaku's family members or Fugaku has to support Naruto in a village - wide crisis, it will show their loyalty to each other and further develop their relationship.
Their relationship can be portrayed as a partnership. They support each other in raising the baby. For example, Sasuke might use his skills to train the baby when it's older, while Naruko imparts her values of friendship and hard work. They also have their own little moments of romance in between taking care of the baby, like sharing a quiet dinner after the baby is asleep.
They could be shown as co - parents, in a sense. Even though they have their own issues, they put them aside to take care of the baby. Their relationship would be one of mutual respect and cooperation for the sake of the little one.
One theme that could be made appropriate is the theme of redemption. Maybe Fugaku has made some mistakes in the past that affected Sasuke, and through a series of events, he tries to make it up to Sasuke. This can be explored without any inappropriate content and still show the complexity of their relationship.
In the original story, Naruto and Sasuke have a complex but deep - rooted friendship. In this fanfiction, the hatred completely flips their relationship. They would no longer be friends but rather rivals or even enemies. There would be no more of Naruto's attempts to bring Sasuke back to the village.
The fanfiction changes the dynamic by making Naruto less empathetic towards Sasuke's past traumas. In the original, Naruto could understand Sasuke's pain to some extent which led to his forgiveness. Here, Naruto is more focused on Sasuke's wrongdoings, like his attacks on the village and his actions that endangered their friends. This makes their relationship more of a stand - off, like two opposing forces.
The change is significant. In the original, they had a bond that was slowly developing. But here, Naruto's hatred means that any positive interactions they had are now replaced with hostility. For example, in the original, Naruto would always try to bring Sasuke back when he left. But in the fanfic, she might be more inclined to stop him by force or even wish him harm.
