It could be Orochimaru. He might be interested in the unborn child for some dark experiment, thinking that the child of Kakashi and Rin could possess some unique abilities. He could send his minions to spy on them or even try to kidnap Rin.
A more complex plot could be centered around any potential threats to Rin during her pregnancy. There could be enemies who see this as an opportunity to target them, so Kakashi has to be extra vigilant in protecting her. This could lead to some intense action scenes where Kakashi uses his Sharingan to fend off attackers while also ensuring Rin's safety.
Kakashi is known for his laid - back yet highly skilled nature. His influence on Naruto could be in terms of teaching him to be more strategic in battles. Rin, being kind - hearted and having a strong sense of care, would give Naruto the emotional support he lacks. So Naruto might become more balanced in his approach to life and ninja - hood.
In a fanfiction of Kakashi and Rin's love story, it could start with their time in the ninja academy. Rin was always drawn to Kakashi's natural talent and mysterious aura. Kakashi, on the other hand, was initially oblivious to Rin's feelings. One day, Rin got injured during a training session. Kakashi carried her all the way to the medical tent. That was the first time he realized how much she meant to him. As they grew older, their bond deepened, and they found themselves falling in love while on various missions.
Growth is also a common theme. The family members, whether it's Kakashi, Rin or their kids, usually experience personal growth throughout the story. They learn from their experiences, overcome difficulties, and become better versions of themselves as a family.
One idea could be that Rin, with her medical skills, tries to save Kakashi but fails due to some unforeseen circumstances. Maybe an enemy uses a powerful jutsu that she can't counter in time. This would be a tragic twist, as her being alive doesn't change the outcome for Kakashi.
