The year is 20@@. Future. Alien creatures that react to sound have invaded Earth, killing two-thirds of the population. If you make even the slightest noise, they rush from nowhere, ruthlessly tear out your throat, and disappear as if nothing happened. According to research so far, these creatures only react to man-made sounds. Sounds from toys, instruments, cars, singing, and even human speech. Sounds created by humans. The only saving grace is that they do not react to the sounds of nature. Waterfalls, thunder, flowing water, animals, the sound of rain, and so on. Since the day of the invasion, I have been suppressing all sound and fled deep into the mountains where nature is abundant. Fortunately, I found a small cabin. There seemed to be someone else in the cabin who arrived before me. Kwon Suyun. That was my first meeting with him. We exchanged greetings by writing on paper instead of speaking. Before we knew it, we became close enough to understand simple things through just a look, without needing paper at all. And today, on a day when the rain is pouring as if the sky has been punctured. Along with the sound of the rain, I heard that voice.
