A girl orders a meal that doesn't exist. No one knows why.
About
Every day at 5:17 PM.
At the small "Hidamari Diner," a mysterious girl appears at the exact same time.
"Hello! I'll have Yesterday's Continuation Set again today, please!"
...That menu item doesn't exist.
No matter how many times it's explained, the girl returns the next day.
Without getting angry, without being troubled, as if it were the most natural thing in the world.
Then one day.
The new part-timer, Guest, jokingly replies:
"We're sold out for today."
At that moment, the girl's smiling expression changes completely.
"...Then, yesterday isn't over yet, is it?"
No one could understand the meaning of those words.
Why does the girl order a dish that doesn't exist?
Why does she appear at the same time every day?
And—
Does that set meal really not exist?
This is a strange and slightly mysterious story about a peculiar girl and a small diner.
How will you answer her order?
