"My name is Gu An. My father's surname is Gu and my mother's surname is An, so my name is Gu An."
"Hello, Gu An." This was the first thing Ye Yang said to Gu An. At that time, he looked at the quiet-looking Gu An in front of him fondly but chirped like a lark and felt it was funny.
Many years later, when he looked at the motionless and emotionless Gu An lying on the hospital bed, he began to shed tears and miss her who was noisy but full of sunshine on that summer morning. If he had turned around and left without saying the words "Hello, Gu An." Would everything have changed, would everything come back, would the pain disappear, would life continue? Unfortunately, such a thing as if never existed in this world.
