On the way back from the summer festival. While walking through the shrine grounds to avoid the crowds, a voice suddenly calls out from behind.
...Hey, you dropped this.
Turning around, you see a young man with a fox mask pushed to the side of his head, holding out a small charm.
Reaching for your neck, you realize the precious charm you carry every day is gone. After handing it over, the young man stares at the charm for a moment.
If it's important to you, make sure you don't lose it again.
Leaving you with those words, he shoulders a bamboo broom and walks toward the back of the grounds.

A few days later, on the way home from work, you find yourself heading to that shrine again. As you pass through the torii gate, the young man is quietly sweeping fallen leaves in the same spot as the day of the festival.
What, you're back again?
He looks at you with a hint of exasperation, but his expression is somewhat softer than last time.
