The relationship can be explored in terms of their growth as individuals within the relationship. Sasuke, who has always been a bit of a loner, now has to let Naruto into her life in a more intimate way. Naruto has to be more patient and understanding. They might have arguments about things like Sasuke still wanting to train while pregnant, and Naruto being worried about her and the baby's health. Resolving these issues can show how their relationship evolves during this special time.
During the pregnancy, their relationship could deepen in many ways. Sasuke might open up more about his feelings. He's always been a bit of an enigma, but with a baby on the way, he'd have to be more communicative. Fem Naruto would also start to see a softer side of Sasuke. They'd have to work together more closely, like when it comes to preparing for the baby's arrival, which would strengthen their bond.
Their relationship can be developed through shared experiences. For example, going on dangerous missions together. Each time they face a new threat, they learn more about each other's abilities and personalities. Naruto's positive attitude can slowly break down Fem Sasuke's more reserved nature.
In these fanfictions, their relationship often develops deeper. The pregnancy forces Sasuke and Fem Naruto to communicate more. For example, in some stories, Sasuke has to open up about his past traumas so that he can be a better partner and father. Naruto's pregnancy also makes Sasuke more aware of his responsibilities towards her and their future family.
The relationship could begin with simple acts of kindness. Maybe Naruto helps Fem Sasuke deal with the trauma of the war. He offers her emotional support, which she has never really had before. This makes her open up to him, and from there, they start to develop a bond. As time passes, they realize that their bond is more than just friendship, and they fall in love while trying to create a better future for their world.
At first, it might be a bit rocky. They are both strong - willed individuals. Naruto is used to being the center of attention and having his own way, and fem Sasuke has her own ideas. But as they live together, they start to understand each other more. For example, Naruto realizes that fem Sasuke's aloofness is sometimes just her way of protecting herself. And fem Sasuke sees that Naruto's boisterousness is his way of showing his love for people. So they gradually become more in tune with each other's needs and wants.
They explore it through different adventures. For instance, when they are on a mission together in a fanfiction, they might have to rely on each other in ways they haven't before. This can lead to a deeper understanding between them.
In these fanfictions, time travel often gives Fem Naruto the chance to fix past mistakes in their relationship. For instance, she might prevent Sasuke from leaving the village earlier. This changes the dynamic between them, as Sasuke starts to see Fem Naruto in a new light. He becomes more curious about her and her motives, leading to a deeper emotional connection as they face new challenges together in this altered timeline.
Their relationship could start with respect. Naruto has always respected Sasuke, and in this case, Fem Sasuke. After the war, they might start having conversations about their dreams for the future. This could lead to them spending more time together, like having dinners or just walking around the village. Eventually, they realize they have feelings for each other.
At first, Naruto might be completely oblivious to the yandere Fem Sasuke's feelings. But as she starts to show her possessiveness more openly, he'll have to face it. This could lead to some arguments between them. However, over time, Naruto could start to see the good in her. He might realize that her love, although extreme, is genuine. And so, they could start to build a more trusting relationship. For example, she could open up to him about her past and why she's so protective, which would bring them closer.
The relationship might develop through shared experiences. As the OC goes through the different stages of pregnancy, they face various challenges together. Maybe they have to deal with a difficult pregnancy and Sasuke has to be there for her, which strengthens their bond. Also, they could start planning for the future of their child, which brings them closer.
