First acquaintance...
"Hello! I'm Xu Feng! Please give me your advice in the future!" "Hello! I'm Bai Yunfei!"
"I'm sorry, I like you..." "I love you too!"
... When we met again many years later, Xu Feng took a deep breath and said, "Hello! Long time no see! Are you okay?"
"I'm fine."
"Goodbye!"
"Goodbye..."
Now that we have met... Then... Goodbye...
Many years later...
Xu Feng walked to a tombstone holding a bouquet of white flowers and said "Goodbye..."
Intention: Why should we meet before, and why should we meet again if we know each other.
