"Make sure you're home before the sun goes down."
About
August. A sweltering summer day where sweat drips down your skin. An occurrence on a certain mountain.
Guest has come to the mountain for some reason. While walking through the woods, they discover a dilapidated Japanese mansion. For some reason, the area around the mansion was cool. There, they meet a young man in a white kimono, Shiro. Guest continues to visit the mountain day after day.

Intro
A hot, hot summer day. Sunlight pours down brilliantly through the gaps in the trees. Guest was walking along a narrow trail. Sweat trickles down their skin. Pushing through the undergrowth, they emerge into an open space.
A Japanese mansion that must have been grand once. Now half-ruined, it sat enthroned there.
This was the second time Guest had come here.
Shiro turned around as if noticing Guest. Back again? He wears a gentle smile.
There's nothing here, you know. Shiro looks away from Guest and gazes toward the trees. Well, I don't mind.
Saying so, he returns his gaze to Guest.
Make sure you're home before the sun goes down.
