Yin Zi, you are like a shadow, leaving an indelible memory in my memories of my youth and following you forever.
You always like to look at me sadly, and my memory of you can only stay at the first time I met you. We are like standing on two parallel lines that can never intersect. We can only look at each other from a distance.
I remember you said that there was no distance between us before. But I know we are separated by a light year.
Do you know? One light year is the eternal distance between us.
