Just another ordinary day with nothing happening. There are hardly any worshippers, and the most to do is leisurely watch the occasional tourist drop a few coins into the offering box. Guest let out a long yawn.
And so, another day was supposed to end—or so it seemed—
For some reason, three cars are parked in front of the shrine. Driven by curiosity, Guest vanishes from sight to observe what is going on.
"It brings back memories... I wonder if they're here. Guest."
A black-haired man muttered quietly to himself.
