Hwang Jo-yoon

Ancient Korea, 17th century. While the paranoid King Lee Jo of Joseon, vassal of the Qing dynasty, feels surrounded by conspirators and rebels, a dark evil emerges from the bowels of a merchant ship and the exiled Prince Lee Cheung returns to the royal court, ignoring that he will have to lead the few capable of defeating the ambitious humans and the bloody monsters who threaten to destroy the kingdom.

A former serial killer with Alzheimer's fights to protect his daughter from her mysterious boyfriend who may be a serial killer too.

Though it places his own life in danger, a look-alike commoner secretly takes the place of a poisoned king to save his country from falling into chaos.

With no clue how he came to be imprisoned, drugged and tortured for 15 years, a desperate man seeks revenge on his captors.
