Perfect? Have you heard their VO's? They sound more like teenagers acting out for attention.
The girl comes off like some faux-edgy teen that brings a knife to school and brags about it to her friends to seem like a badass... and the boy seems more like that obnoxious kid who acts like an even BIGGER obnoxious idiot because he likes attention. Seriously... I'm shocked one of his lines isn't "lol wut". They both remind me of what adults think kids might "identify with" these days. The girl is for the wannabe edgelords out there that feel like rebelling against mom and dad makes them hardcore, and the guy is a slightly older version of the kid who would eat worms and used chewing gum for attention if you dared him to with his friends watching.
