Sakura would probably be very hurt at first. She might cry a lot and feel betrayed. But then, she'd likely draw on her inner strength. She is a strong - willed character after all. She could focus on her work as a medical ninja to distract herself from the pain. And she would also have her friends to turn to for support, like Naruto who has always been there for her.
At first, Sakura would be devastated. She might go through a period of denial, not wanting to believe that Sasuke has left her in such a situation. But as she starts to accept it, she would become angry. This anger could fuel her to become more independent. She would train harder in her ninja skills and also study more about medicine to be the best mother she can be. She would also try to find positive things in the situation, like the fact that she will have a part of Sasuke with her in the form of the child. And she would use her love for the unborn baby to overcome the negative emotions.
Another reaction could be that Sakura tries to follow Sasuke. She believes that she can change his mind or that she can be of help to him. She might leave her own responsibilities behind for a while to chase after him, thinking that their bond is strong enough to overcome whatever is making Sasuke leave.
In such a fanfic, it might explore the challenges they face. For example, Sasuke's past actions might make some in the village still be wary of him. But Sakura's pregnancy could be a symbol of hope and new beginnings. It could also show how their friends like Naruto react to the news. Naruto, being Sasuke's long - time friend, would likely be overjoyed and offer his support, while also teasing Sasuke about becoming a dad.
She could also try to find Sasuke and clear up any misunderstandings. Sakura is not one to give up easily, especially when it comes to someone she loves. She might set out on a journey to find him, believing that she can bring him back and make him realize the importance of their family.
The dynamic would be turned upside down. Sasuke would likely become more of an outcast or a loner, feeling rejected. Naruto would be in a difficult position, having to balance his friendship with Sasuke and his new relationship with Sakura. Sakura would be the catalyst for this change, and she would have to face the consequences of her actions, like dealing with the villagers' opinions and the potential backlash from Sasuke's supporters.
He could initially be in disbelief. However, as the reality sinks in, Sasuke would start to show his softer side. He might be more attentive to Sakura's needs, like making sure she eats well and rests. He would also start thinking about how to train their child to be a strong ninja in the future, while also wanting to give the child a more peaceful life than he had.
In this scenario, Sakura's character development would be complex. At first, she may be in a state of shock and denial. But as time passes, she would have to grow up fast. She would learn to manage her finances, her living situation, and her emotions all at once. Her relationships with her friends would also change. Some friends may be overly helpful while others may distance themselves. Through all this, Sakura would emerge as a more resilient and self - sufficient woman, ready to face any challenges that come her way for the sake of her child.
Another great one is 'Pregnancy and Promise'. This fanfic emphasizes the promises Sasuke makes to Sakura and their unborn child. It shows the emotional turmoil and the hope that comes with the pregnancy in their relationship.
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 would probably be initially very angry. She has strong feelings for Sasuke, but kidnapping is a very extreme act. So she would likely fight back, using her medical ninjutsu skills and combat abilities to try and escape.
One possible plot could be that Sasuke and Sakura have finally reunited after his long journey. They decide to settle down and start a family. Sasuke, who has now found peace, is initially a bit nervous about becoming a father but with Sakura's support, he gradually embraces the idea. The fanfic could then focus on their journey through Sakura's pregnancy, from the first signs to the final preparations for the baby's arrival.
