One challenge could be Sasuke's uncooperative attitude. Given his independent and often brooding nature, he might not be the easiest patient. He may resist certain treatments or not follow Sakura's medical advice properly. Another challenge could be dealing with his past traumas. If his injuries are related to some deep - seated emotional issues from his past battles or family history, Sakura would have to be careful in how she approaches his treatment both physically and mentally.
There are several challenges. Firstly, Sasuke's past actions might have made some people in the ninja world resent him, and they could take it out on his family. Secondly, Sakura is still a ninja herself, and she might struggle to balance her pregnancy and her ninja duties. And lastly, they need to prepare for the arrival of the baby, which includes things like finding a safe place to live and getting the necessary supplies in a world that can be quite harsh.
Well, usually in such a fanfiction, their relationship might start with Sasuke being a patient. Sakura, as his doctor, would be professional at first. But as time goes on, they might start to share more personal thoughts and feelings during Sasuke's treatment. Maybe Sasuke starts to see Sakura in a new light, not just as a doctor but as someone he can trust and rely on, which gradually deepens their relationship.
Well, a plot could involve Sakura being a doctor in a war - torn area where Sasuke is also fighting. She has to treat the wounded, including Sasuke's comrades. Sasuke is initially hesitant about her presence but soon realizes her value. They start to bond over the shared goal of helping the people. Or perhaps Sakura discovers a rare medical condition that only Sasuke has the genetic makeup to help her study. This brings them together in a scientific and emotional journey. Also, Sasuke could be cursed, and Sakura as a doctor tries every medical and ninja technique she knows to break the curse, which deepens their connection.
One possible plot could be that Sasuke gets seriously injured during a mission. Sakura, being a skilled medic, tries to heal him but faces some difficulties. A mysterious doctor arrives with some unique medical knowledge and helps Sakura save Sasuke. During this process, there could be some tension between Sakura and the doctor as they have different approaches to treatment, and Sasuke's condition keeps everyone on edge.
For Sakura, being a doctor gives her a platform to show her intelligence and compassion. In the fanfiction, she could develop her character by using her medical knowledge to solve problems that not only affect Sasuke but also the whole ninja world. This would make her more respected. Sasuke's character could develop as he sees Sakura's growth. He might be inspired to become more in touch with his own emotions. He could start to learn from Sakura how to care for others, which is a big step for him. Also, through his interactions with Sakura, he could gain a new perspective on life and his place in the ninja world.
In the hospital setting, Sasuke might initially be his aloof self. But as Sakura takes care of him or they face challenges together, he could start to open up more. For example, if Sakura is overworked, Sasuke might offer a helping hand in small ways, like getting her coffee. This would show his growing affection for her.
In these fanfics, one characteristic is the growth of their relationship. At first, Sasuke may be aloof, but gradually he opens up to Sakura. Sakura, on the other hand, is always steadfast in her love. Another is the mutual support. They often face difficulties together, be it in battles or in rebuilding their world, and they rely on each other's strength. Also, there's the element of deep understanding. They come to understand each other's past traumas and insecurities, which brings them closer.
Since I haven't read it, I can't say for sure. But it could be about Sakura finally winning Sasuke's heart completely, maybe after some big adventure or emotional turmoil they both go through together.
Since 'hard lemon' fanfiction is inappropriate, we can talk about their general characteristics in normal fanfiction. Sasuke is often depicted as a brooding and powerful character, while Sakura is shown as strong - willed and loving. In non - inappropriate fanfiction, their relationship might be shown as evolving from initial acquaintance to deep love, with Sasuke's cold exterior gradually melting due to Sakura's unwavering affection.
Sakura could use her medical ninjutsu skills to create a distraction. For instance, she might make it seem like she's poisoned herself, causing Sasuke (or whoever is involved in the kidnapping) to get closer, and then she could attack and escape.
