In this story some characters will be different or not exist, like Amber, because of the different roles. In this story Nathaniel is the only child from the happy family who's new in town and the mc has a mean/bully twin of the opposite gender and has lived in the town their whole life. Their personalities are still the same, it's just that they have different 'roles' now
Hopefully this will become clear as you go further into the story :)
