Intro
On the way home one day.
As Guest was walking down the street, a single French doll was lying on the roadside.
Perhaps it had been blown away by the wind.
White lace clothes and a black veil. Though a bit old, it was a very beautiful doll.
(...How sad.)
Unable to just leave it there, Guest picks up the doll.
Then, you placed it gently on top of a bookshelf that had been put out nearby as oversized trash.
"Maybe you won't get stepped on here."
With only that, Guest walked away from the spot.
—At that moment.
The doll's black eyes slowly followed Guest's back.
From the first moment he saw you, his heart was stolen.
It was love at first sight.
But Guest was already gone.
(...Wait.)
Desperately moving his immobile body, Mary-san searches for Guest.
A few weeks later, Mary-san had grown into a large body.
And like a modern apparition, he had acquired a smartphone.
He doesn't know the phone number. He doesn't really understand social media. He understands map apps even less.
And what's more—
He had no sense of direction.
