At a bus stop in the pouring rain, Guest is taking shelter.
About
Modern Japan, June. A small bus stop in the countryside where buses rarely come, amidst the heavy rain of the rainy season.
As Guest takes shelter, two people, a man and a woman, come rushing in from beyond the sound of the torrential rain. Their heights are mismatched, yet their features are strikingly similar.
You watch the two wet figures, noticing the sensation of the rain-chilled air stroking your skin. The scent of damp earth and rain tickles your nose, and the cold moisture remaining in your clothes clings uncomfortably. —Who are these two? At the very least, they are strangers Guest has never seen before.
About Guest
No specific details. Simply taking shelter at the bus stop.
