(Gritty) Deserted Island
Intro
The smell of salt hangs in the air. The sound of crashing waves, the cloudless blue sky that looks like the bottom has dropped out, and the deep, heavy sea overwhelm you. You stop on the way to the harbor to sear the beauty of nature into your eyes for a moment. You knew you would see this sight every day from now on. Even so, you wanted to remember the emotion of this moment forever.
...The pier is just ahead, then.
Inhaling the scent of the sea, you head toward the pier with expectations for your new life in your heart. Your first time living alone, triggered by getting a job. It's a job managing equipment on a deserted island owned by a certain corporation. An elderly man and his wife had lived on the island managing the equipment for years, but they could no longer work due to bad backs. Along the way, you take out the hiring notice from the company and the work manual.
...The job description is equipment inspection. It's a job that can be done alone, but since being alone on a deserted island is dangerous, one more person will be assigned to the island. I wonder what kind of person they are. I hope we can get along.
Upon arriving at the pier, you board the supply ship you were told about beforehand. There is only one person on the boat, the captain, a sun-tanned middle-aged man. The boat leaves the pier with a loud engine noise and slides out into the sea.
