One interesting plot point could be that the OC has a connection to Kakashi's past. Maybe she is related to someone from his past in a way he doesn't expect. This discovery makes Kakashi re - evaluate his relationship with the OC. At the same time, the OC is dealing with her own issues at school, like not fitting in with the other students. Kakashi helps her through this, and their relationship grows stronger as they face these challenges together.
The plot could involve a prophecy about the OC. Kakashi, being her teacher, is determined to protect her from whatever the prophecy foretells. As they search for ways to prevent the prophecy from coming true, they develop a deep bond. Also, the OC could come from a different clan with unique traditions. Kakashi has to learn about these traditions to better understand the OC, and this cultural exchange enriches their relationship.
A good plot point could be the student OC having a hidden power. Kakashi discovers this during training and is both curious and worried. He tries to help the OC control this power. This could lead to a series of training sessions where they get closer. Another plot point might be a rival who is jealous of the OC's relationship with Kakashi. This rival tries to create misunderstandings between them, which they have to overcome.
One plot idea could be the student reader struggling with a difficult jutsu, and Kakashi takes them aside for special training.

Another idea is that the reader is on a dangerous mission and Kakashi, as their teacher, has to make a tough choice to protect them, which reveals his hidden feelings.
One way to develop their relationship could be through mentorship. Kakashi, as the teacher, could start by seeing the potential in the student OC. He might give her special training, which gradually builds trust. For example, he could teach her a new jutsu and during the process, they start to understand each other better. Then, as the OC grows stronger, Kakashi might start to see her as more than just a student, and there could be a mutual respect that slowly turns into a deeper connection.

One popular 'kakashi x oc fanfiction' story could be 'A Ninja's Heart'. In it, the OC might be a new ninja in the village who catches Kakashi's attention during a mission.

Well, first of all, it violates the basic ethical norms. Kakashi is a teacher - like figure, and having a relationship with a student in that way is just wrong. Moreover, from a creative perspective, it can distort the original image of the characters.

Also, it may make some readers uncomfortable as it contains inappropriate implications.
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.

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.
The theme of redemption also appears often. If the male oc has a dark past or has made mistakes, Kakashi serves as a guiding light. He helps the oc to atone for his actions and find a new purpose in life. This often involves a lot of self - discovery for both characters.
One plot idea could be that the OC is a ninja from another village who has a secret relationship with Kakashi.

The story might be about the OC having a special power. Kakashi is initially intrigued by this power and then falls for the person behind it. Once married, they work together to use the OC's power for the good of the village. They might also have some domestic scenes, like cooking together and having small arguments over silly things that show their normal married life.
