In a fanfiction, Kakashi might see Naruto crying after a particularly tough mission. Kakashi immediately goes into mentor mode. He takes Naruto to a quiet place and offers him some advice. He says that crying is a way to let out the pain and stress, but then Naruto needs to pick himself up. Kakashi then starts to train Naruto right there, showing him new jutsu to distract him from his sadness and also to make him stronger for future challenges.
One possible fanfiction could be that Kakashi stumbles upon Naruto crying alone in the forest. He sits beside Naruto quietly, not saying a word at first. Then he gently puts his hand on Naruto's shoulder and tells him that it's okay to cry, that showing vulnerability doesn't make him weak. Naruto then pours out his heart about his loneliness and how much he misses his parents. Kakashi listens intently and shares some of his own experiences of loss, creating a deep bond between them in that moment.
Kakashi might immediately offer a comforting presence. He could put his hand on Naruto's shoulder and just be there silently, letting Naruto know he's not alone.
Their relationship is like a mentor - mentee bond. Kakashi has trained Naruto, and when he sees Naruto achieve great things, it can be overwhelming. For example, when Naruto masters a new jutsu that Kakashi thought was difficult for him, Kakashi might cry out of joy for Naruto's accomplishment.
One possible reason could be that Naruto is feeling lonely. Despite having friends, there are times when his past as an orphan and the years of being shunned by the villagers resurfaces, making him feel isolated. Kakashi finding him in such a state might then lead to a heart - to - heart conversation about Naruto's inner struggles.
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.
In the fanfiction, after Hinata sees Naruto crying, Naruto might initially try to hide his tears and put on a brave face. But Hinata's gentle persistence makes him break down further. This then leads to a chain of events where other characters start to notice the change in their relationship. Some might be supportive, while others could be jealous. The situation could also lead to Hinata and Naruto teaming up to face a common enemy or problem, with their newfound emotional bond strengthening their resolve.
Kakashi would probably be very calm at first. He's an experienced ninja who has seen a lot. He'd gently pat Naruto on the back, offering silent comfort. Then he might start to speak softly, asking Naruto what's wrong in a gentle voice.
The plot might involve Naruto crying due to a misunderstanding with his friends. Kakashi witnesses this and steps in to mediate. He first calms Naruto down and then arranges for Naruto and his friends to have an open conversation. During this process, Kakashi shares some wisdom about friendship and communication, helping them resolve their differences.
Kakashi would probably first check if Naruto is hungry or needs a diaper change. If that's not the case, he might hold Naruto close and gently rock him while humming a soft tune.
Perhaps Naruto has just learned some dark secrets about his past, such as the truth about his parents' death. Discovering such painful truths could easily make him break down and seek comfort in Kakashi, who he looks up to as a mentor. Also, it could be that he's feeling lonely. Despite having friends, there are times when the weight of his responsibilities makes him feel isolated, and crying in Kakashi's arms is a way to let out those pent - up emotions.
Sakura could be the one to find him crying. She has known Naruto for a long time and they are comrades. If Naruto is in a vulnerable state, she might stumble upon him.
