It is a love between two people for two lifetimes, with no real ending.
He sent his lover away with his own hands, explained everything, and left himself alone to face death.
The playback pans the world, but the fate has not changed. It's like a fixed chess game. No matter how tenaciously you struggle, in the end it will lead to death. This seems to be a good choice.
Purpose: Telling a tragedy in a love story
