Behind   the thick veil, in the middle of forest where the trees are obscured by mist,  on the otherside of the dowdy wall  rules another goverment.                                                                                                                                 

Kim Jongin has always dreamed someday to be able to meet the world outside the great walls                                                                    

But then, his dream suddenly came true when he got selected to be a member of a special unit                                                                                                

But sooner or later he’ll realize that his life is going to change…                                                                                                                       

He has to change….                                                                                                                                                                                                           

He’ll learn to accept the fact that there will be casualties, failures, traitors, loss of friends and mostly loss of his beloved ones                                                                                                                                                                                                                

There will be many times where he’ll have to stand up and choose the right decision.

And then there's is Krystal...
