Pen pals are very popular, and at the instigation of my best friend, I became a pen pal with the mysterious man.
But in the process of writing the letter, I gradually discovered that he knew my true identity, but I knew nothing about who he was.
He has maintained his own sense of mystery over and over again, and how can I tolerate it...
When the mystery is lifted, in reality we don't know how to be friends. It turns out that our thoughts are no longer pure as time goes by.
Life is a long river, endless, we seem to have lost each other, but in fact no one has really left.
