Sakura could use her intelligence to prove her strength. She has a sharp mind and is able to analyze situations quickly. For example, she can figure out the weaknesses of her opponents during a battle. By using her intelligence in combination with her skills, she can show Kakashi that she is a force to be reckoned with.
Sakura could prove them wrong by showing her medical skills. In many Naruto scenarios, her ability to heal the injured is crucial. For example, she was able to keep many ninjas alive during battles. Also, she has been training hard in combat. She might challenge one of the members of Team 7 to a spar and show her newfound strength and skills.
Another way the plot could develop is that Sakura confronts Kakashi directly about his comment. They have a heart - to - heart conversation where Sakura reveals her insecurities but also her determination to be strong. This could lead to Kakashi mentoring her more closely, helping her to reach her full potential and strengthening their relationship in the fanfiction.
He could also get angry. After all, being misjudged like that is unfair. His anger could lead him to either lash out verbally at Sakura or he could leave the village in a fit of rage, feeling that he is not accepted even by his friends. This could then lead to a series of events where Naruto has to find his own way and Sakura realizes her mistake later on.
She might be really hurt and start to question her self - worth. Maybe she becomes more withdrawn and less confident in herself.
Sakura may feel a bit suffocated by his possessiveness. She is a strong - willed and independent ninja herself. So, if Kakashi's possessiveness restricts her freedom or her ability to grow as a ninja, she could get angry. She might confront him and tell him that she needs space to develop her skills and make her own decisions, even if she respects his concern for her safety.
Regular Kakashi and Sakura fanfiction usually focuses on their relationship in a more general sense, like friendship or mentorship. But 'hard lemon' fanfiction (if we assume it's not inappropriate) might explore more intense emotions or situations between them, perhaps more romantic or even angsty scenarios that are not typically explored in the regular ones.
Well, in addition to Kakashi and Sakura, there might be other characters making brief appearances. For instance, Naruto could pop in for a short visit while Kakashi is there. Or maybe Tsunade could be mentioned, as Sakura's mentor, in relation to her current situation that led to Kakashi's house call. But at its core, it's about Kakashi and Sakura and their interaction.
Perhaps it's a more light - hearted story. Kakashi makes house calls not for any serious reason but just to have a friendly chat with Sakura. They could end up sharing stories about their training, their friends, or their dreams. It could be a way for them to bond outside of the normal ninja - related activities.
Sakura might initially be shocked and resistant. She is a strong - willed character, so she could try to fight back or find a way to escape this forced situation. Maybe she would first confront Sasuke about his unacceptable behavior.
He might be really hurt. Naruto has always been an outcast and being called a demon again could reopen old wounds. So he could just stand there in shock and disbelief, his eyes wide with pain.
