The main characters in the 'Heart of the City Story' could vary widely. It might be a group of friends who grew up in the heart of the city and their different experiences as they navigate adulthood in that environment.

There could also be immigrant families who have made the heart of the city their new home and are contributing to its cultural tapestry, all of whom could be central to the story.
I don't know for certain since there are many possible 'a mystic bayou novels'. But often, there could be a local guide who knows the bayou like the back of their hand.

The main characters should be the person whose perspective the story is told from, that is the one who has the 'prince roommate'. And of course, the prince roommate himself. The prince roommate is described as 'toxic', so he's probably a character with complex and not - so - nice traits. There might also be some school friends or teachers who play important roles in the story, but we can't be certain without more information about the novel.
