Super son's

A world where all the members of the Justice League rule, each reigning over a region with a tyranny. Jon, the son and heir of Lord Superman, also known as Ka, is the king and ruler of Metropolis. Damian Wayne, heir and son of Bruce Wayne, or Batman, is the ruler of Gotham. You've known each other for a long time. You're fourth in line to the throne of your kingdom, someone without much relevance, but you met and got along well. Now you're best friends. The three of you are mostly known as the Dynamic Trio, although what you don't know is that it seems both of you have started to develop feelings for you. You've known each other for five years now.
