Sasuke would likely experience a mix of emotions. On one hand, he might be filled with joy as he does care for Sakura deeply. But on the other hand, he could also be worried about his enemies finding out and using his family against him. He would then start to plan how to strengthen his defenses and make sure Sakura has a safe pregnancy.
Sasuke might initially be shocked. He has always been a bit aloof and focused on his own goals. But once the shock wears off, he would probably feel a sense of protectiveness over Sakura and their unborn child. He'd start to think about how to keep them safe in the dangerous ninja world.
Well, in many fanfictions with this plot, Sasuke's realization of Sakura's pregnancy can be a turning point in their relationship. It could strengthen their bond as he realizes the depth of their connection through this new life they are about to bring into the world. It might also bring out his softer side that was hidden due to his past traumas and his lone - wolf nature.
Sakura might initially be a bit annoyed by Sasuke's possessiveness. She's a strong - willed woman, after all. But she also understands that it comes from his love for her and the baby. So, she may tolerate it to some extent.
There are several challenges. Firstly, Sasuke's past actions might have made some people in the ninja world resent him, and they could take it out on his family. Secondly, Sakura is still a ninja herself, and she might struggle to balance her pregnancy and her ninja duties. And lastly, they need to prepare for the arrival of the baby, which includes things like finding a safe place to live and getting the necessary supplies in a world that can be quite harsh.
Sasuke may initially freeze in disbelief. His mind would be racing with thoughts. He might recall all the things he has been through and wonder if he can provide a stable and loving environment for the child. After a moment of silence, he would probably hold Sakura's hand tightly and tell her that he will be there for her and the baby, no matter what challenges lie ahead.
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.
Sasuke would likely first show a stoic exterior when he finds out. However, internally, he's in turmoil. On one hand, he's happy that he and Sakura are going to have a child. On the other hand, he's worried about the potential dangers his family could face because of his past enemies. So, he might start making plans to keep them safe, like finding a more secure place to live.
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.
Sakura could also try to stand up for herself. If she believes that Sasuke is being unfair in his anger, she may argue back. For instance, if Sasuke is angry because of a misunderstanding, Sakura might try to clarify the situation and prove her point.
She may initially be angry. Sakura is a proud and strong character. She could confront Sasuke and Ino, demanding an explanation. After that, she might decide to become even stronger, both in her ninja skills and her emotional resilience, to show Sasuke what he's missing.
In some fanfictions, Sakura's reaction could be more complex. She might be hurt not just physically but also emotionally. This could lead her to question her relationship with Sasuke and might cause her to make some big decisions, like whether to continue trying to reach out to him or to cut him off completely.
