Perhaps in our lives, there will be such an emotion, existing in dreams, hearts, and past days and nights, but missing out on our future. One day, I woke up from the beautiful dream, and I accepted that relationship that no longer belonged to me. I began to try to forget it and never think about those good old days again. Until the secret was revealed, but dear, you made me understand too late. It turned out that it was not just an illusory dream.
