One possibility could be that in the fanfiction, Yugito is jealous of Naruto's close relationship with another female character. Maybe Naruto has a strong bond with Sakura in this fanfic, and Yugito, who has feelings for Naruto, can't stand seeing them interact so casually. This could lead to some interesting scenes of Yugito trying to come between them in a rather comical or angsty way.
The plot could be that Yugito is jealous of Naruto's friendship with Hinata. Hinata is always shyly helping Naruto and Yugito misinterprets their interactions as something more. So, she tries to get closer to Naruto by challenging Hinata to various tasks. But Naruto is oblivious to Yugito's feelings at first, which adds to the drama.
Naruto in this fanfiction would be his usual self - full of energy and always ready to jump into action. His positive attitude could be a source of inspiration for Yugito. Yugito might be portrayed as a bit mysterious initially. She has the power of the two - tailed beast within her, which gives her an air of danger and strength. She may be reserved, but as the story progresses, we might see her softer side when she's around Naruto.
Naruto might also feel a sense of responsibility. He might think that he did something to cause Yugito to act this way. So he could start to limit his own actions to avoid triggering her yandere behavior. For instance, he might stop being so friendly with other girls in front of her. But at the same time, he would not give up his own dreams and values, and would try to make Yugito understand that her behavior is not acceptable in a way that is both firm and kind.
Their relationship could start as comrades in misfortune. As they face the hardships of being banished, they rely on each other more and more, gradually developing a deep bond of friendship. Over time, this could turn into a romantic relationship as they realize how much they mean to each other.
His relationship with Sasuke would likely be very different. Without the shared experiences in Konoha, their initial rivalry might not be as intense. Naruto might not be as desperate to bring Sasuke back. And his relationships with his other Konoha friends like Sakura and Kakashi would also change. He'd be more connected to Yugito's friends and allies instead.
Their relationship would transform into a true partnership. Naruto, who has always been about protecting the village and his friends, would now have a new focus on protecting his family. Yugito, on the other hand, would rely on Naruto more for emotional support during the pregnancy and after the baby is born. They would share the joys of seeing the baby's first steps, first words, etc. Their relationship would be centered around the well - being of their child, and they would do whatever it takes to ensure the baby has a happy and safe life.
Well, in a Naruto marries Yugito fanfiction, it could be a story full of adventure and love. Yugito has her own story arc and powers in the Naruto world. When combined with Naruto, there would be countless plot possibilities. For example, they could go on adventures together to explore the secrets of the tailed beasts. Their marriage could also be a symbol of unity between different Jinchuriki. Naruto's friends would probably be very supportive, especially since Naruto has always been someone who values relationships. And Yugito's friends in the Cloud Village might also come to respect Naruto more through their relationship.
There could be. Naruto has a huge fan base, and fanfiction writers often come up with unique scenarios like this. You can try looking on platforms like FanFiction.net or Archive of Our Own. But keep in mind that not all fanfictions are well - written, and you might have to sift through a lot to find one that suits your taste regarding this particular 'Yugito pregnant' concept.
Well, in a fanfiction like this, it could explore Naruto's sage mode abilities in a new context while he's with Yugito who has also been banished. Maybe they form an alliance to fight against the forces that banished them. They could discover new powers together and change the shinobi world's view of them.
