Perhaps the fanfic could start with Sakura hiding her pregnancy complications from Sasuke because she doesn't want to worry him. But as the situation worsens, she has no choice but to reveal it. This could lead to some initial misunderstandings between them. Sasuke might feel betrayed that she didn't tell him sooner, but then they quickly put aside their differences to focus on dealing with the health crisis. And throughout the story, their love for each other and their hopes for their future family could be what drives them to overcome all the obstacles.
A possible plotline could be that Sakura discovers she has a rare and dangerous pregnancy complication. Sasuke, initially shocked, vows to protect her and find a solution. He might go on a journey to find a rare herb or seek the help of a reclusive healer. Meanwhile, Sakura is in the village, trying to stay strong and use her medical skills to keep herself and the baby alive as long as possible.
I haven't actually read this specific fanfic. But if it's about Sakura having pregnancy complications while Sasuke is involved, it could be a very emotional and complex story. It might explore how Sasuke reacts to the situation, whether he's supportive or if there are conflicts due to his past and his nature. Maybe it also delves into how Sakura copes with her own health issues while being a shinobi and a soon - to - be mother.
Perhaps Sasuke uses Sakura to get closer to some information. He might know that Sakura has connections or knowledge that can help him in his quest for revenge or for protecting the village. So he uses her in a strategic way while she is initially unaware of his motives. As the story progresses, their relationship could develop in complex ways.
One possible plotline could be that after Sasuke has finally returned to the village and reconciled with Sakura, they start to rebuild their relationship. They go on dates, share their feelings and experiences during their time apart, and gradually their love deepens until they reach a point of expressing their physical love for each other.
One possible plotline could be Sasuke becoming increasingly possessive as Sakura's popularity or friendships grow. He might start to isolate her from others, thinking it's for her own good.
One possible plotline could be a story set in an alternate universe where Sakura is pregnant. Kakashi could be her mentor, guiding her through this new phase of life while also dealing with Sasuke's return to the village. Sasuke might initially be hesitant about the pregnancy but then gradually grow to accept and support Sakura.
Maybe Sakura teaches Sasuke about emotional control. Sasuke has always been brooding and angry, and Sakura, with her more empathetic nature, could show him how to manage his emotions better. This could lead to Sasuke becoming a more well - rounded ninja and a better teammate.
Maybe Sasuke is jealous because Sakura has achieved some great feat in the ninja world and is getting a lot of attention. In the fanfic, this could lead to Sasuke training even harder to prove himself worthy of her. Sakura, on the other hand, might be confused by Sasuke's sudden distance. She could try to reach out to him, but Sasuke's pride and jealousy keep him from being receptive. It could all come to a head during a dangerous encounter with a powerful enemy where they finally communicate their feelings.
One possible fanfic could be where Sasuke and Sakura's relationship has developed to a point where they are expecting a child. It could focus on Sakura's journey through the pregnancy, her emotions, and how Sasuke is dealing with the upcoming addition to their family. Maybe it shows Sasuke becoming more protective and Sakura being excited yet a bit nervous about motherhood.
One possible plotline could be that Sasuke, feeling conflicted by his past and the secrets he holds, distances himself from Sakura and starts to develop an inappropriate emotional connection with someone else, which Sakura misinterprets as cheating. As for Itachi's role, perhaps his memories or the influence he had on Sasuke play into Sasuke's actions, like Sasuke trying to live up to some ideal Itachi had that made him question his relationship with Sakura.
A plotline might involve Sakura facing a lot of judgment from the village. But she stands strong and raises the child with the help of her friends like Naruto and Ino. They support her emotionally and sometimes even materially. As for Sasuke, he might be on a journey of self - discovery and when he hears about the pregnancy, he has to decide whether his path still lies away from Konoha and his family or if he should change his ways.
