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.
It could start off rocky. Boruto might be judgmental of Teenager Naruto's wild ways. But as they get to know each other, they could become friends. Boruto would see the good in his father's younger self.
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.
In fanfiction, they could have a sort of brotherly relationship. Boruto might see Kid Naruto as a younger version of his father, but also as an individual with his own charm. They would play pranks on people together, and when it comes to serious ninja business, they would have each other's backs. Boruto would protect Kid Naruto from some of the tougher enemies he might not be able to handle yet, and Kid Naruto would keep Boruto's spirits high with his positive attitude.
At first, they might be a bit suspicious of each other. Boruto has heard stories about Kurama but has never really interacted with him. Kurama, on the other hand, might be cautious as Boruto is Naruto's son and not sure if he can be trusted. But as they spend more time together, they could start to respect and rely on each other.
Naruto would become even more affectionate and protective towards Hinata. He'd be constantly by her side, making sure she has everything she needs. Their relationship would deepen as they share the excitement and anticipation of the new baby.
In a 'naruto dies boruto fanfic', Boruto's character would go through a major transformation. He would be forced to grow up overnight. Initially, he might be consumed by anger and a desire for revenge if Naruto was killed unjustly. But as time passes, he would learn to channel that energy into positive change. He would study his father's leadership style and try to implement it in his own way. He would become more diplomatic, forging alliances with other villages to strengthen Konoha's position. His sense of justice would be refined, and he would be more committed to protecting the world his father loved so much.
Their relationship could develop through shared experiences. For example, if they both get involved in a dangerous fight against a common enemy, they'll start to trust each other more.

If they got married, their relationship might start off rocky. Naruto has always been headstrong and Sakura has her own strong will. They would need to learn to compromise.

They could support each other in their ninja duties, with Naruto providing physical protection when needed and Sakura using her medical skills to keep him healthy.
