One common plot point is that there was a secret relationship between Kakashi and Naruto's mother. Maybe they had a brief encounter that led to Naruto's conception. Another point could be some sort of memory - wipe or secrecy spell that kept this fact hidden for a long time. Then, as the fanfiction progresses, the truth slowly starts to surface, usually through some sort of discovery or accident.
Well, often in these fanfictions, there is a backstory about how Kakashi was involved with Naruto's mother in a way that wasn't known before. It could be that Kakashi was on a secret mission, and during that time, he met Naruto's mother and they had a relationship. Then, there might be a conspiracy within the Hidden Leaf Village to keep this relationship a secret, which adds an element of mystery and intrigue to the plot. Also, the fanfiction might explore how Kakashi's personality and actions towards Naruto change once he discovers or is revealed to be Naruto's father.
In fanfiction, anything is possible. However, in the original Naruto series, Kakashi is not Naruto's father. But in the realm of fan - created stories, an author could come up with an interesting plot where Kakashi is Naruto's biological father, perhaps by creating some elaborate backstories and twists to make it seem plausible.
One common plot point is a situation where Naruto and Kakashi are in a life - threatening situation. This could lead to a moment of intense emotion and then the kiss. Another is Naruto realizing he has deeper feelings for Kakashi over time, perhaps through a series of adventures together. Sometimes, there's also a magical or supernatural element involved that makes the relationship more acceptable or even necessary in the story.
Often, there's a plot point where Naruto discovers a hidden talent or power on his own because Kakashi isn't there to guide him. He might also get into more trouble than usual as he tries to prove himself without Kakashi's approval. And sometimes, the other members of Team 7, like Sasuke and Sakura, start to notice Kakashi's neglect of Naruto and try to make up for it in their own ways, which can create some interesting group dynamics in the fanfiction.
Often, one plot point is the initial shock of the marriage within the Naruto universe. People around them are surprised. Another is the adjustment period where Kakashi and Naruto learn to live together and understand each other's habits. For example, Naruto's messy eating habits compared to Kakashi's more refined ones.
Perhaps a significant plot point is Naruto trying to copy Kakashi's relationship with his students. Kakashi has a certain way of mentoring his students like Sasuke, Sakura, and Naruto himself. Naruto might try to adopt Kakashi's teaching methods when he has to train others, but his own exuberant nature could make it a completely different and engaging experience in the fanfiction.
One common plot point is Naruto's internal struggle with her feelings. She might be afraid of rejection or worry about how it will affect their team dynamic. Another is Kakashi's reaction when he finally realizes her feelings. He could be surprised or initially hesitant.
One major plot point is the adjustment of their relationship. Naruto might initially be shocked or overjoyed to find out Kakashi is his brother. Then they have to figure out how to act around each other. Another plot point could be the impact on their respective goals. Naruto's goal of becoming Hokage might be influenced by having Kakashi as his brother, and Kakashi's role in the village and his own personal missions could also change due to this new family connection.
The plot could involve Kakashi adopting Naruto. Kakashi would then be responsible for Naruto's upbringing, teaching him not only ninja skills but also life lessons. For example, he could teach Naruto how to cook simple meals, which is a basic life skill. This would show the domestic side of their father - son relationship.
The plot could revolve around a time -travel scenario. Naruto somehow gets sent back in time and meets Kakashi's father. Together, they could work on changing some of the events that led to the darker times in the village's history. For example, they might try to prevent certain tragedies that affected Kakashi's family.
One common plot device is the revelation of a hidden past. For example, there could be a long - lost memory or a secret agreement that ties Kakashi to being Sakura's father. Another is the use of emotional turmoil. Sakura might find out about this relationship in a very dramatic way, like during a battle when she's at her lowest point and this revelation gives her new strength.
