One possible story could be that Shikamaru and Sakura start off as friends. They've always been comrades in their ninja village. As time passes, they find themselves growing closer during a difficult mission. They realize they have a deep connection and feelings develop. Eventually, they decide to start a family. Their baby could inherit Shikamaru's intelligence and Sakura's strength. It would be a new chapter in their lives filled with the joys and challenges of raising a child in the ninja world.
The plot could revolve around a mission where they are forced to take care of a baby for some reason. This baby then turns out to be their own in a strange twist. Shikamaru is initially reluctant but slowly warms up to the idea of fatherhood. Sakura is more immediately attached. As they try to find out how this happened, they also grow closer as a couple and start to envision a future with their new family member.
Shikamaru would probably become more involved in village politics to ensure a good future for his child. He'd use his intelligence to make connections and secure resources. His character would shift from just being a member of a team to a family man with big responsibilities. Sakura would find a new balance between her ninja duties and motherhood. She might train other female ninjas on how to handle both aspects. Her love for Shikamaru would grow as she sees him change and become more committed to their family.
One possible plot could be that Shikamaru and Temari are initially nervous about becoming parents. Shikamaru might worry about how to balance his duties in the village with being a father. Temari could be concerned about adjusting to life in Konoha while raising a child. As the story progresses, they could face challenges like protecting their baby from potential threats. Maybe an old enemy resurfaces and they have to use their skills to keep their family safe. They also learn to rely on each other more and grow closer as a couple through the experience of raising their child.
The baby would definitely change their priorities. Shikamaru, who used to be more laid - back, would become more responsible. He'd need to think about providing for the family and protecting them. Sakura would have to balance her medical ninja duties with motherhood. Their social lives would also change. They might not be as available for missions or hanging out with friends as much. The baby would be the center of their world now.
A different fanfiction could explore an alternate universe where Shikamaru and Sakura are paired as genin teammates instead of Naruto and Sasuke. Their journey would be very different from the original story. Shikamaru's intelligence combined with Sakura's book - smarts and physical strength could make them a formidable team.
Sakura may become more patient. In the original story, she can be a bit hot - headed, but in the arranged marriage scenario, she has to deal with Shikamaru's laid - back nature. So she learns to be more patient. Shikamaru, on the other hand, might become more responsible. He realizes he has a partner to take care of and can't just be lazy all the time.
One possible story could be that Sasuke returns to the village after his long journey. He and Sakura finally have time to be together. They discover they're going to have a baby. Sakura is both excited and a bit worried. Sasuke, though not very expressive, is secretly overjoyed. He becomes more protective of Sakura. As the pregnancy progresses, they start preparing a room for the baby. Sasuke might even go on small missions close to the village to get things for the baby.
Sakura is a very empathetic person, especially with her medical skills. In a marriage with Shikamaru, she can understand his needs and feelings easily. Shikamaru, who is often seen as aloof, can be brought out of his shell by Sakura's warmth. His intelligence and ability to analyze situations can be beneficial for Sakura too. For instance, if there are any political or social issues in the village that affect their family, Shikamaru can figure out the best way to deal with them. Sakura's kindness and Shikamaru's wisdom can make their relationship a stable and loving one.
