The ballad of the gem decorating the last of the large lost love trilogy which did a true experience of "Kaijyu" oneself following "Souka" where "Kokuhakushoku" in a song. "That there is surely a moment to yearn for the important person who can never meet" anyone anymore incidentally I yearn for me saying that I was able to come back in the past even if I know the parting when after all I want to meet you.
