每个人，都有一个世界，安静而孤独的住着一些心事。Everyone, there is a world, quiet and lonely there lived some worry.
那只是一段浅浅的过往，却不知觉地凝成了悲伤。It's just a shallow, it is condensed into sorrow.
孤单，是你心里面没有人。 寂寞，是你心里有人却不在身边。 No one is alone, is your heart. Lonely, is your heart someone but not around.
时光，就这样在我们回首追寻中，兜兜转转间，一去不返。Time, so in pursueing we look back, for a walk, never look back.
