[Hetalia AU] Erstwhile - a word meaning "former," or "formerly." Fitting, to describe your life. After leaving the home you loved in order to be free, you and your childhood friend Emil must struggle through the world on your own in order to find the secret behind his power and also the secret to controlling it. After meeting many strange people, facing many setbacks, and not even having a clear goal, is it really possible for Emil to save himself, or be consumed by his own raging emotions? {This would be my first fanfiction on Wattpad, so I really hope I don't do *too* bad of a job!}
