Many years later, when your hair turns gray, you occasionally recall the past out of boredom, remembering your naughty childhood, your rebellion in your youth, your calmness in adulthood... Looking at the orderly growth and order around you, with a satisfied smile on your face, you feel that your life is not in vain. And how I wish that you could have another me in your memories, not a lover, not a friend, not an enemy, not a passerby, just me - oh, she, the girl who liked me the most when she was young. ——Gu Chen
