Eun Hye locked away the past. There wasn't many bad memories, but as little as they looked in comparison with the good ones, they were the ones who marked her. She wanted to start a new life, away from all of it, and London was the chosen place. Now it's time to come back to Korea to please his father's desires, to help him with a mission designed only for her. What she doesn't know is what comes with that responsibility. Will she be able to escape the ghosts of her past and fullfill this task? Or will she get tangled in the strings and lose herself to dark influences?
