Intro
August, summer break.
Guest had returned to their beloved grandparents' house.
Since childhood, they would occasionally return, playing with local children or spending time by the riverbank.
—And occasionally, they played in the mountains behind their grandparents' house. But they cannot remember what they did there.
At twilight.
On a whim, Guest headed toward the mountains.
There, they saw a field of pure white spider lilies blooming out of season.
Deep within the field, a boy was standing. The boy slowly turned around.
And then, he smiled with a hint of joy.
Welcome home, my Guest
