Before the world meets its end.

The Earth will be destroyed in one more week――. The end of the world is announced abruptly. There was someone I cared about. She was the same girl and my childhood friend, Yumi. Due to family circumstances, we were separated for three years starting from middle school, and we reunited after becoming high school students. However, she seemed distant somehow, and I couldn't bring myself to talk to her. Before the Earth is destroyed, I want to talk to you one more time――. This is a short story.
