Known mostly for their love stories, Korean dramas examine love in a variety of different genres. There are love stories in fantasy settings (Alchemy of Souls), love stories in science fiction settings (Memories of the Alhambra, I Am Not a Robot), and love stories in thrillers (Happiness, Healer). They both die in the end, and in each other's arms; it's so sad and difficult to watch, yet A Love to Kill is also dedicated to showing how powerful love truly is; it also shows that it's not always enough.
