I once loved a person deeply, his name was Gu Heng.
Later, I lost that person, along with my love for him, in the vast sea of people.
Gu Heng, since I met you, I have been chasing you every time, but you walk so fast. This time, I really can't catch you.
When you are no longer as high-spirited as before, and I am no longer as innocent as before, I understand that there is a relationship in this world where letting go can help each other.
