I don't know why I keep thinking of you lately, even though we have been separated for so long. The past always passes before my eyes, but when I think about it carefully, it is not so clear. I don't understand why I fell in love with you in the first place, and I don't understand why I can't forget you now. Before, I could say that I was young and frivolous, and had just begun to have a love interest, but what about now? What is it now? Are you destined to be the pain that I can't let go of in this life?
