There is a small side story in The Long Journey Home, which is somewhat related to the plot. I don't know where to post it, and I'm afraid it will affect the main text, so I posted it separately.
They met when they were young, in their youth,
Those restlessness and pure love were given to each other.
When they were both famous, they had already separated, and they were on opposite sides of the world.
The roads we have walked, the love words we have spoken, the hands we have held, the shoulders we have embraced,
But it remains in life forever, becoming a hard thorn in my heart,
Underneath the gorgeous scenery, there is a dull pain.
