The theme of self - discovery can also be associated with Boruto crying in fanfiction. As he grows and learns more about himself and his abilities, there may be moments of confusion and fear that result in tears. For example, when he discovers a new power within him that he doesn't know how to control. Also, the theme of loss is common. If he loses a friend or a mentor, it would be a very emotional moment for him and crying would be a natural reaction.
Perhaps Boruto cries when he realizes he has made a big mistake that has put his friends in danger. He is a character who values his friendships deeply, and the thought of harming his friends would be a huge blow to him. He might also cry when he witnesses the destruction of the Hidden Leaf Village or when someone he cares about gets seriously injured.
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.
Maybe it's the high expectations that Naruto has for Boruto. Naruto is a hero, and he might unknowingly put a lot of pressure on Boruto to follow in his footsteps. Boruto could be scared of not being able to meet those expectations.
They could start by having an honest conversation. Naruto could sit down with Boruto and just listen to his fears without judgment. This would be a first step in building a better relationship.
Boruto's reaction would be complex. He'd be heartbroken, for sure. He might start to question his own worth and purpose. But over time, he'd realize that he has to carry on Naruto's legacy. He'd become more serious and focused. He'd also become more empathetic towards others, understanding the weight of sacrifice. He might even start to study Naruto's techniques and leadership style more closely, trying to emulate the things that made Naruto such a great Hokage and hero.
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.
One possible reason could be that Naruto is feeling lonely. Despite having friends, he still has moments when the weight of his past, like being an orphan and ostracized in the village as a child, hits him hard. Jiraiya might see Naruto crying because of these memories resurfacing.
