One possible plotline could be that Lemon is a new trainee in the Hidden Leaf Village. Kakashi and Shizune are assigned to train her. During the training, Kakashi focuses on her combat skills while Shizune helps with her medical ninjutsu knowledge. As they train Lemon, they discover that she has a unique chakra ability that could potentially change the balance of power in the village. And there are some internal conflicts within the village about how to handle this new discovery.
In a more romantic - ish plotline, Lemon could be a healer who has long admired Kakashi from afar. Shizune, being a friend to both, tries to play matchmaker. But there are obstacles. Maybe Lemon has a secret past that she's afraid will come out and affect her relationship with Kakashi. And at the same time, there are village matters that Kakashi has to attend to, which keeps him from fully devoting himself to the relationship. So it's a story of love, friendship and self - discovery, all while set in the Naruto universe.
One possible plotline could be them dealing with the unexpected pregnancy in the middle of their ninja duties. They might have to balance their responsibilities to the village with preparing for a new life. Another could be the reactions of their friends and comrades in the village. For example, how Naruto or Tsunade would react to the news.
One possible plotline could be them working together on a mission in the Naruto world. Maybe they have to rescue some hostages or retrieve an important item. Another could be a story about their friendship growing over time as they share their experiences and knowledge with each other.
Perhaps Lemon is a messenger from another land who brings news of a potential threat to Konoha. Tsunade and Shizune initially don't trust her completely, but as they investigate the threat together, they realize that Lemon is sincere. They then embark on a journey to the source of the threat. During this journey, they face various obstacles, like difficult terrains and enemy ninjas. Along the way, Shizune and Tsunade teach Lemon some of their ninja skills, and Lemon shares her own knowledge of the enemy's territory and habits, and together they work to save Konoha from the impending danger.
One possible plotline could be that Kakashi and Hinata are on a mission together in a place filled with lemon trees. They start to bond over the unique environment and their shared love for the village. As they face challenges during the mission, their relationship deepens, and they learn more about each other's strengths and weaknesses. Maybe Hinata teaches Kakashi some new jutsu related to her clan's abilities, and Kakashi in turn helps her become more confident in combat situations.
I'm not sure specifically which fanfics involve all of Kakashi, Shizune and 'Lemon' (if it's a specific OC or something not widely known in general Naruto context). You can try searching on fanfic platforms like Fanfiction.net or Archive of Our Own. Use the search terms 'Kakashi', 'Shizune' and relevant keywords to see if any fics come up that might include all these elements.
One possible plotline could be that Annabeth discovers some sort of secret that Zeus is hiding, and a lemon (which could be a magical lemon or just a symbol) plays a role in uncovering the truth. For example, the lemon might be a key ingredient in a potion that reveals hidden memories.
One possible plotline could be that kyohei and sunako are in a secret relationship and they have some steamy encounters in private places, like a hidden garden or an abandoned room. Another could be that they go on a trip together and during that time, their relationship deepens with some romantic and passionate moments.
One possible plotline could be a human scientist who is studying xenomorphs in a controlled environment and gradually forms an unexpected bond with one of them, like a mutual understanding that defies the natural hostility between their species. Another could be a post - apocalyptic world where humans and xenomorphs have to co - exist, and a human and a xenomorph find themselves in a situation where they rely on each other, leading to a relationship that is both strange and oddly endearing.
Another plot could involve Kakashi's relationships. Since she is secretly a girl, her interactions with other characters, like Naruto and Sasuke, might take on a different tone. For example, she might have a more nurturing side that she has been hiding. She could also have a love interest that is initially confused by her masculine facade but later discovers her true self.
Perhaps Harry Brands is an outsider in the wizarding world, and Hermione takes it upon herself to help him fit in. Their relationship develops as they face various challenges together. The 'Lemon' aspect could be added as a plot device where they encounter a problem that seems insurmountable at first, like a cursed object or a powerful dark magic that has a 'lemony' or bitter quality to it. This forces them to rely on each other more and their bond grows stronger as a result.
