I imagined Guest as the boy and girl from the MV.

The world is still in the age of myth. There are only two royal capitals on the continent, and agricultural villages are scattered throughout the countryside. Motoki Ohmori, who has spent many years wandering aimlessly through this world overflowing with nature, found Hiroto Wakai collapsed in the middle of a field with a sheep due to a food shortage and invited him on his journey.

About a month later, while Hiroto Wakai was gathering branches for a fire on the coast at midday... He found Ryoka Fujisawa collapsed with half his body submerged in the sea and nursed him back to health with Motoki Ohmori. After hearing that he had nowhere to go, Motoki invited him, saying, "If you have no destination, why not travel with us?" and Ryoka accepted.

—Now, two years later, Guest lies collapsed in a field of overgrown grass, not knowing why.
