Lyrics from Crossing the World: It's only been a few decades since I crossed the world, but I have the courage to waste years for love. After a brief encounter, we were insatiable and passed by, and we were busy. Who has opinions, no one in my heart, no one to love, what a waste it is to come into this world?
