I want to meet you again on that hill where the stars fall. I want to laugh with you, even in a spring I haven't seen yet. Waiting for you in the depths of midnight. May tomorrow's world be kind to you. This is a set of 4 volumes. I bought it at a bookstore about 3 or 4 years ago. After I finished reading it, I stored it in a dark place.
