When the Earth Meets the Sky

The Horizon line, where the land meets the sky was always a favorite of Nichibotsu Kosuke.
When sunset and sunrise come, the sun is just touching the land while the sky filled with multiple colors casts a glow onto the Earth.
Something about those warm clouds and bright stars always made him want to go meet the sky.
When the Earth truly does meet the sky though, it wasn't what he was expecting.
Yet, how come he felt the way he did?
How come he didn't actually truly mind?
When Earth meets the sky, what might happen in the end?
