[A dark, gentle, and extremely strong bottom x a domineering, dark, and extremely strong top]
Seven days ago, a sudden downpour covered the entire world. Anyone caught in the rain vanished for no apparent reason.
The country tried countless ways to stop it, but to no avail. They thought it was a harbinger of the apocalypse, but seven days later, the rain vanished as quietly as it had come.
Yet the people who had vanished did not return. No one knew whether they were dead or alive, and no one knew they were searching for a way home at the edge of the world.
