Outcasts aren't born, they're made

Think of a world with 4 outcasted teens.

Once a bunch of childish children with their own lives like any other, but turned to teens with their precious memories taken away from them.

People can go through tragic things in their lives. But don't exaggerate when meeting them. They've suffered much...much worse.

How will things turn out for these 4 teens? Will there be friendship, happiness, or freedom? Or tragedy, betrayal, and grief?
