Another way is to have them open up about their pasts. Michael could share more about his family problems and how he got into the criminal life. Trevor could talk about his own traumas. By understanding each other's backgrounds better, they can become closer friends. They might start to see each other in a new light and be more empathetic towards one another. This could lead to them being more protective of each other in future situations.
A plot could revolve around them starting a new business together. Since they both have different skills, Trevor's wild and fearless nature combined with Michael's more strategic thinking. They face challenges from competitors and have to figure out how to keep their business afloat while also dealing with their personal issues.
Given the lack of context, Michael could be anyone. He might be a local storyteller in a small town, known for his engaging tales. Or perhaps he's a character in a story within a larger narrative, like a character in a novel who has a story - telling role.
