Just because I heard a song called "Long Time No See", I thought of the person I hadn't seen for a long time, the most shining light in my youth, the past I thought I would never forget. Until I met you again, everyone smiled and exchanged greetings, and understood that we have always had each other in our hearts, but so what, you are not the original you, and I am not the original me. We will all have a new life. I am very good now, really very good. I would like to write this article to commemorate the purest love when we were young.
