I used to love someone so much, but in the end I just got a blue-faced confidant. I still can't let you go, but one day, you will no longer be so important in my life. There may be such a person in each of our lives. Although we love him, we may not be able to be with him. Even if you no longer have to travel thousands of miles to find him, even if you never mention him, you will always remember him until you die.
