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 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.
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.
Maybe Naruto is crying over a failed mission where he blames himself for the outcome. Sakura sees him and at first is shocked as Naruto is usually so strong. She then consoles him, reminding him of all the times he has succeeded and how this one failure doesn't define him. This could lead to a growth in their relationship where Naruto starts to see Sakura as more than just a teammate.
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.
One possible plotline could be a comical take where Naruto, perhaps as a baby or in a situation where he's regressed to a younger state in diapers, accidentally uses his newfound baby - like clumsiness to his advantage in a prank - like way against his friends. For example, he might 'accidentally' spill something on someone while being carried, leading to a series of funny events.
One possible plotline could be that Naruto and Ino are on a mission together. They start off bickering like they used to in the original series, but as the mission progresses, they begin to understand each other better. For example, they might face a powerful enemy that forces them to rely on each other's unique skills. Naruto's brute strength and Ino's mind - control abilities could complement each other in combat. Another plotline could be a more emotional one where Ino helps Naruto deal with his inner demons related to his past. She could use her skills to get inside his head in a more positive way and help him come to terms with things.
Perhaps a plot where Himawari discovers a new and rare chakra ability, and Naruto helps her to understand and control it. They might go on a journey to find someone who can further teach her about this power. This could involve meeting old friends of Naruto's along the way and having various adventures together.
A possible plot could involve a mystery within the village. Naruto, being smarter, is the first to piece together the clues and solve the mystery. Shikamaru, who usually excels in such situations, is left playing catch - up. Naruto could use his intelligence to not only solve the mystery but also prevent a greater disaster from befalling the village, showing that his intelligence is a valuable asset to the community.
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.
One possible plotline could be that Sakumo is in a dangerous mission situation where he is outnumbered and on the verge of defeat. Naruto, with his powerful jutsu and never - give - up attitude, arrives just in time. He uses his Rasengan to take out the main threats and then uses his shadow clones to rescue Sakumo from the surrounding enemies.
