Since Sakura is a skilled medical ninja, the baby might also have an aptitude for medical ninjutsu. It could show an early interest in healing small wounds of its toys or pets. The baby might be able to combine the power of the Sharingan with medical ninjutsu, for example, using the Sharingan to better analyze internal injuries and then using medical ninjutsu to heal them more effectively.
One possible plot could be that Sakura and Sasuke face challenges in raising their baby in a world still recovering from past battles. The baby might inherit some unique abilities from both of them, and they have to protect the baby from those who might want to use its power. For example, some old enemies of the Uchiha clan might see the baby as a threat or a tool.
After getting married, their relationship might develop with more trust. Sasuke, who has always been a bit of a loner, would start to open up more to Sakura. He would share his thoughts and feelings with her, which would make their bond stronger.
Itachi is a very complex and reserved character, while Sakura is strong - willed. Their relationship could start with Itachi being somewhat of a mentor to Sakura in terms of combat strategy. Sakura would be intrigued by Itachi's calm and calculating nature. As they spend more time together, Sakura might start to see the softer side of Itachi that he hides from most, and this could lead to a deeper connection.
Often, in fanfiction, Sasuke's romance with Sakura develops as they face challenges together, and he realizes her importance and starts to express his love more openly and passionately.
His personality could be a blend of introversion and extroversion. In some situations, he would be like Sasuke, preferring to be alone and train or study. But when it comes to protecting his friends or family, he would show an extroverted side, being vocal and taking charge, much like Sakura when she is in a leadership role. He would also have a great respect for the ninja way, having been brought up hearing stories from his parents about their adventures and sacrifices.
One of the most popular themes is redemption. Sasuke has made many mistakes in his past, and fanfictions often explore how Sakura can be a part of his journey towards redemption. For example, she might help him face his inner demons and find peace within himself.
There's a fanfiction where Sasuke and Sakura are on a mission together in a foreign land. They encounter many challenges that force them to rely on each other more than ever. This story could explore their growing bond as they face these difficulties, and how their feelings for each other develop in the midst of danger.
Sasuke would become more nurturing. He'd have to learn patience which was not his strong suit before. His cold exterior would start to soften as he takes care of Naruto.
Sakura is often portrayed as a strong - willed and intelligent character. She's no longer just the girl pining after Sasuke. She's shown using her medical skills and combat abilities. Sasuke is usually depicted as brooding but with a soft spot for Sakura. His complex past still haunts him, but he's gradually opening up to her.
Itachi's Sharingan abilities could influence the baby's upbringing in terms of combat training. He might start teaching the baby early on about how to perceive and counter different types of jutsu using the Sharingan's powers of perception. For example, the baby could learn to quickly analyze an opponent's movements and weaknesses. Sakura, on the other hand, would focus on the baby's physical well - being and medical knowledge. She would ensure the baby has a strong body and teach it about basic first - aid and how to use chakra for healing from a young age.
