One unique way is through art. Suppose the genin are all into drawing and painting as a way to express their ninja skills in a different form. Kakashi, who is initially skeptical, starts to see the value in it. He then uses their art as a way to teach them about strategy and stealth. For example, they draw maps of their training grounds and use the art to plan their attacks and defenses. This creates a really different and interesting bond between them.
The relationship could be developed through a shared love of food. Maybe the genin are all food enthusiasts and Kakashi, who usually doesn't show much interest in food, starts to enjoy cooking with them. They bond over trying new recipes and sharing meals, which in turn makes their ninja training sessions more enjoyable and productive.
Perhaps there's a group of genin who are all small and cute but have some hidden powers. Kakashi is assigned to protect them from a group of rogue ninjas. As they journey together, Kakashi discovers that the genin have powers that are related to ancient ninja arts long forgotten. They must work together to defeat the rogues, with Kakashi learning as much from the genin as they do from him.
A possible storyline could be that the genin discover a hidden treasure map. Kakashi decides to accompany them on the adventure to find the treasure. Along the way, they face various traps and enemies. Kakashi uses this opportunity to not only protect the genin but also to train them further. The genin also get to know more about Kakashi's past and his own experiences as a ninja during this journey, which deepens their bond with him.
The fact that Kakashi is such an iconic character and his genin are so endearing makes it appealing. Fanfiction can create new adventures for them. We can see the genin in situations where they have to rely on Kakashi completely or where they surprise Kakashi with their new skills. It also gives room for creativity in terms of the settings, like sending them to a new and unknown land where they have to work together. The relationships, the growth, and the new possibilities are what make this type of fanfiction so attractive.
Their relationship could be developed uniquely by having Kakashi become a more emotional mentor to the female Naruto. Instead of his usual calm exterior, he shows vulnerability in front of her, which makes her see him in a new light. This could lead to a deeper level of trust and friendship between them.
Their relationship could develop through mutual respect. As they work together on Anbu missions, they come to appreciate each other's strengths. For instance, Kakashi might admire Sakura's determination and her growth as a ninja, while Sakura could respect Kakashi's wisdom and combat experience.
Flashbacks can also play a crucial role. By showing their past interactions, even if brief, it can add depth to their relationship. Maybe a flashback of a time when Naruto was a child and Kakashi saved him secretly in his Anbu days. This would create an unspoken bond that could be explored further in the fanfiction.
They could be like mentor and student. Kakashi could be teaching Sakura some new jutsu or ninja techniques while they are sitting on the bed. Sakura is eager to learn and Kakashi is patiently guiding her, with the bed just being a convenient place for them to sit and have this educational interaction.
In fanfiction, the possessive relationship can start with Kakashi noticing Sakura's growth and potential. He might become possessive as he sees her as a valuable asset to the team and someone he wants to protect at all costs. For example, he could start giving her special training, but in a way that shows his possessive nature, like not allowing others to interfere with her training time.
Communication is key. If they sit down and talk about their misunderstandings and feelings, it could start to mend their relationship. Naruto could express his frustrations, and Kakashi could explain his actions.
Sakura could also develop her sense of humor. Since Shikamaru has a dry sense of humor, she might start to pick up on it and use it to lighten tense situations. This not only adds a new dimension to her personality but also helps her bond better with Shikamaru. On the other hand, Shikamaru can develop his leadership skills further. With Sakura as his teammate, he has to take into account her ideas and abilities more, which forces him to be a more inclusive leader and grow in that aspect.
