You said that we will never see each other again, but I forgot to ask you whether we will never see you again, or whether we can't see you again, so now I am guarding an empty city, remembering reluctantly alone, but not knowing how to live. Facing the place where the sun rises, but I can't see the sun. Please tell me whether it is to the left or the right. North and south are too far, and I can only choose one side.
