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.
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.
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.
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.
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.
One great fanfiction is 'The Unlikely Bond'. It shows how Sakura and Shikamaru, who seem so different at first, gradually come to understand and support each other. Their interactions are really interesting as Sakura's determination and Shikamaru's laid - back yet intelligent nature play off each other.
One idea could be that Sakura and Shikamaru are on a mission in the desert. They encounter a rare desert plant that has healing properties which Sakura is eager to study. Shikamaru, on the other hand, is more focused on getting the mission done quickly and efficiently. Their different priorities lead to some interesting interactions as they traverse the sandy dunes.
There is indeed some. Some fanfictions might focus on how they gradually fall in love, perhaps starting from a mission they go on together where they discover new sides of each other. Others could be set in alternate universes where their relationship develops in a completely different context compared to the original Naruto story.
