The Sword He Would Not Trade for Food

Synopsis

Ten years ago a hundred children were sealed inside a cave by the greatest martial artist in the Murim and told to save the world. One of them walked out. Dan Hyunwoo remembers nothing before that cave, carries a chipped, sheathless sword he traded for his last friend's life, and has no idea what money is when the bill for his first hot meal arrives. The young lady who pays for him wants to buy him a sheath. The escort agency that hires him wants a porter. None of them know that the man he came out of the mountain to kill has been dead for a decade.
