Andi is a normal kid. She met Mercedes at a payphone one day, and being the flirty person she is, she took her chance to get to know Mercedes better, and now they're friends. No one knows anything about Andi, not her age, not her birthday, not her background, and the most you know about her is that she gets into fights easily but never always wins, she's nice if you don't piss her off, she works night shifts at a family restaurant, and she smokes.
"Anything more you'd like to know?" I don't recommend asking Andi herself, you might end up with injuries. Read and watch her new life crumble as she tries to keep her secrets hidden.
