A mild breeze is blowing along the vast grassland,
the sun is glowing brightly above the grassland,
a horse is careering quickly in this immaterial area.
The horse has been living here for more than seventeen years,
no one knows where it comes from.
The horse is exceedingly pure,
we can't find any splotches on its body,
living with other animals happily for most of the time.
in this enormous grassland,
there is only one horse,
and thus it finds the life is boring sometimes.
The horse keeps on running and trampling.
Finally, it comes to the edge of the grassland.
What is surrounding the grassland is just water,
it wants to get through the water and explore its life.
But it can't, because it doesn't swim.
It feels really upset and doesn't run anymore, staying and having a cloistered life there.
Time flies, today is its birthday.
It has already been living here for exactly eighteen years.
It should feel happy but it doesn't,
just staying along the edge of the grassland as normal, waiting somebody.
Seemingly out of the blue,
someone is whistling to it.
