Chaeyoung: "Who are you? And what's your story?" My family left the world and gave me their last wish. To look over you from now on. "Mina!.... What am I suppose to do about you?" Jihyo: "Where are you right now? My words is the only tangible prove of your existence." After you left, I sealed all my feelings onto that book, and denied it's ownership. "If I see you again, I will make sure to sacrifice my most valuable treasure..." Jeongyeon: There is no more "You" in my life for two years now. As I know you don't exist anymore in this world, I will make sure to avenge your death. Just then, maybe I will rest in peace. Dahyun: "My eyes on you, and you alone." No one can see you the way I do. Wait a little bit more, be sure that I am going to save you.
