Kakashi would be more reserved but still show his support. He might give Sasuke some advice on being a father based on his own experiences with his team. Shikamaru would be practical, thinking about how the baby will affect the village's future and offering some logical solutions to any potential problems that might come up.
The other female ninja in the village would likely be very supportive of Sakura. They might have baby showers for her and share their own experiences of pregnancy. As for the male friends like Choji and Kiba, they would be happy for Sasuke and Sakura, and might tease Sasuke a bit about becoming a father and how his life is going to change completely.
Sasuke would likely be initially shocked. He's a man who has been through a lot and is used to a life of solitude and danger. But then, a sense of protectiveness would kick in. He'd become more vigilant about the safety of Sakura and their unborn child. He might also start to think about how to be a better father than his own was, in some ways, trying to break the cycle of his family's past.
In this fanfiction, the relationship between Sasuke and Sakura could be deepened by the pregnancy. They might face challenges like how to raise a half - vampire child. Sasuke, with his past and his vampire nature, would have to come to terms with being a father. Sakura, on the other hand, would use her medical knowledge and her love for Sasuke and their child to face whatever comes their way.
One possible fanfiction could be that Sasuke returns to Konoha after a long mission. Sakura, who has been longing for his return, discovers she is pregnant. This news brings a mix of joy and worry. The village of Konoha is also excited as it means a new generation is coming. Sasuke might initially be shocked but then becomes determined to protect his family and the village.
Naruto would be deeply saddened. He has always hoped for Sasuke and Sakura to be happy together. He might initially try to mediate and get them to work things out, believing that their relationship can be salvaged. He would remind them of the good times and how much they mean to each other.
Sakura would be over the moon. She would blush deeply and look at Sasuke with so much love in her eyes. She might be at a loss for words for a moment, but then she would find her voice and tell Sasuke that she has been waiting for this moment her whole life. She would also feel a sense of pride that Sasuke has chosen her, after all they have been through. And she would immediately start thinking about how to share the good news with their friends, especially Naruto, who has been like a brother to her and has also been a part of their journey.
Sakura might be initially frustrated. She's used to Sasuke being in control, so seeing him drunk could be a bit of a shock. But then she'd probably feel a sense of protectiveness and try to sober him up.
In some fanfictions, Sakura may be determined to find Sasuke and bring him back. She could set out on her own journey, facing various challenges along the way, and growing both as a person and as a ninja in the process of trying to reunite with him.
The other members of their team or the village might have mixed reactions. Some might side with Sakura, understanding her point of view, while others might think she's being hasty or that they should try to preserve the relationship for the sake of the village's stability or their own friendship circle.
Sasuke might be initially surprised. He is used to the Sakura from his past, so seeing a different, more mature future Sakura could catch him off guard.
In fanfiction, Sasuke's realization of Sakura's pregnancy can be filled with drama. He might question his own ability to be a father. However, his love for Sakura would drive him to overcome his doubts. He could start learning about pregnancy and child - rearing, and his relationship with Sakura would become more affectionate and caring as they anticipate the arrival of their baby.
