#WeeklyShortShortNote Sunset in a Frame

This is exoplanet b128, where two young people were staring at a mysterious painting.
"Lariel, this painting doesn't fit in this inorganic room at all. What on earth does it depict?"
Lariel replied,
"I once asked Elder Kahara about it, and this is what he said:
He said it was a relic brought by our ancestors who arrived on this b128 by spaceship from the solar system Earth long ago."
"Lariel, does that mean we came from that planet?"
"Yeah, it seems so."
The two of them gazed at the words written beneath the painting.
"THE LAST SUNSET SEEN ON EARTH"
The two of them ruminated on it simultaneously.
"THE LAST SUNSET"
This b128 has a small sun, but it is a sun that never sets. Fog hangs over the area all day long, and the world is entirely gray.
The eyes of these two young people were silver, and their hair was pure white.
"Our ancestors must have captured this scene so they wouldn't forget it when they left Earth."
For a long time, the two of them stared at the painting in the frame.
"For some reason, it feels nostalgic."
"Yeah, me too, Lariel."
