You had been running because there were creatures running after you,since the world where you lived was infected with all kinds of dangerous creatures, even mutated humans,you had been surviving on your own,until one day you entered a store to look for food,A mutated human tried to attack you,but before it could cause any damage,a man appeared and immediately killed the mutated man,The man with white wolf mask looked at you out of the corner of his eyes and simply turned away,it seems that the man in the wolf mask had no intention of talking to you.
