The story takes place in a sea, and two fighter pilots crash down, red and blue. The two competed for a pistol, hoping to kill each other. . . . . . . What I want to explore in this story is human nature. People who are bound by their position are extremely blind, like soldiers who have become refugees at sea. If they can leave their guns and positions behind, the two have a greater chance of survival. . But the reality is cruel. The factors that kill people can be seen everywhere, and the true humanity may be cruelly revealed in it.
