I'm not sure specifically as I haven't read that particular fanfic. But generally, in a Naruto fanfic, it might be about some sort of relationship or situation involving Naruto and Mikoto Fugaku in a creative and fictional scenario that the author has come up with.
There are also Naruto - specific fan communities and forums where fans might share or discuss fanfics. Websites like Reddit have Naruto - related subreddits where users sometimes post links to interesting fanfics. But be cautious when using such sources as the legality and quality of the fanfics can vary. Additionally, make sure to respect the rules of these platforms and not engage in any unethical or illegal activities while searching for the fanfic.
Naruto might be initially confused. He's used to people being friendly or at least straightforward with their intentions. So when Mikoto starts showing her yandere side, like getting overly possessive, Naruto would probably be like 'What's going on?'. He could try to talk to her and understand her behavior at first.
Sasuke would likely be a bit stunned at first. He's a complex character. But then he would become very protective. He has lost so much in his life, and he wouldn't want to lose Sakura or the baby. He might become more vigilant and even cut back on some of his more dangerous missions.
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.
Themes of loyalty and betrayal can also be present. For example, loyalty to their respective clans versus loyalty to each other. There might be situations where they have to choose between their clan's interests and their relationship. Additionally, some fanfics might explore the theme of redemption, especially if one of the characters has made mistakes in the past. Their relationship could be a means of finding redemption or a new path in life.
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.
Kushina and Fugaku are the main characters. Kushina has her own unique personality traits like her strong will and her red hair which is kind of her signature. Fugaku, on the other hand, is a powerful and stoic leader of the Uchiha clan. In this fanfic, they are likely to be the central focus, with their actions and interactions driving the story forward.
One popular 'fugaku adopts naruto' fanfiction might be the one where Fugaku discovers Naruto's potential early on. In this story, Fugaku takes Naruto under his wing, training him in the ways of the Uchiha. This changes Naruto's life completely as he now has the support and training of one of the most powerful clans in Konoha.
