In those years of youth, there are always many people appearing in our lives in a hurry.
Let us be happy, let us be sad, let us gradually see ourselves clearly.
And we don't know how long they will stay, whether for a lifetime or just for a moment.
However, those who have appeared will always leave something behind for us.
Let us not forget it for a long time.
There is no sadness in youth, and all pain is embellishment of a happier life in the future.
