After her entire family is slaughtered, she becomes the blind daughter of a disgraced official. A hypocritical scoundrel tricks her into a cage, and she mistakes the man who saved her life for her enemy. A black-clad assassin watches over her from the shadows and takes blows meant for her, only to be met with her sword. Not until the truth comes to light does she understand: the most painful thing in this world isn’t hatred. It’s crushing with your own hands the heart that would have given everything for you.
