Perhaps Shikamaru has made a decision that deeply affects Naruto. For example, Shikamaru might choose to leave the village for a dangerous solo mission. Naruto, who values their friendship, cries because he's worried about Shikamaru's safety and the thought of losing his friend. In the fanfic, this could lead to Naruto trying to convince Shikamaru to change his mind.
One possible plotline could be that they are forced to work on a long - term mission together. During this mission, they have to rely on each other, which deepens their connection. Another could be that Temari visits Konoha and Shikamaru is assigned to show her around. They start to see each other in a new light.
Another plotline could revolve around how their friends and the ninja community react to the pregnancy. Some might be supportive, while others could be against it due to various reasons, like clan politics or traditional values. There could also be a plotline where Naruto discovers she's pregnant during a dangerous mission and they have to find a way to protect both her and the unborn child while still completing the mission.
Naruto's impulsive nature could be shown when he's crying. Maybe he cries because he rushed into a situation without thinking and it backfired. Shikamaru's cautious personality would then contrast as he scolds Naruto gently but also helps him fix the mess. This would show how their different personalities play off each other in the fanfic.
Another plot could be that they travel to a future time where Konoha is in ruins. They have to figure out what went wrong and try to change the events that led to this destruction. Shikamaru could use his intelligence to analyze the situation, while Naruto uses his determination and strength to fight any threats they encounter. Maybe they find out that an old enemy has returned in a new form and they must stop it.
Well, it's a really strange concept considering the nature of their relationship in the official Naruto story. Naruto is married to Hinata and Shikamaru is married to Temari. But in the world of fanfic, the author can create all kinds of scenarios. Maybe there could be some kind of magic or alternate reality situation that leads to Naruto having a child with Shikamaru in the fanfic world. But it goes against the established relationships and personalities in the original series.
One possible plotline could be that Jimin is facing extreme pressure from the idol life. He might be crying because of the intense schedules, the high expectations from fans and the media. For example, he has to constantly practice, perform and do promotional activities without much rest. In the fanfic, he could reach a breaking point during a particularly tiring tour and break down in his dressing room.
A possible plotline is that a powerful villain threatens both Naruto's world and Alita's world. They are brought together by a mysterious force to stop this villain. Along the way, they face many challenges as they try to understand each other's powers and cultures. For example, Alita may not understand the concept of ninjutsu at first, and Naruto may be baffled by her mechanical body.
One possible plotline could be Naruto ending up in Alois' world and having to adapt to its different rules and power dynamics. He might use his ninja skills in unexpected ways to survive and make a name for himself.
A plotline could involve Islamic mythology or figures somehow making their way into the Naruto universe. Maybe an Islamic - inspired spirit or entity appears in the Hidden Leaf Village and has to be dealt with, and the characters learn about Islamic beliefs in the process.
A plotline for a Naruto Keyblade fanfic could start with Naruto finding a strange Keyblade - like object during one of his missions. As he tries to figure out what it is, he accidentally activates it and is sent to a different realm. In this realm, he meets other Keyblade wielders who help him understand the power of the Keyblade. Meanwhile, back in the Naruto world, his friends are worried about his disappearance and start searching for him. Naruto then has to master the Keyblade and find a way back home while also dealing with any threats in the new world.
