The world has become a little too hard for you to live in, hasn't it?
・The harmful effects of constant SNS connectivity ・The doctrine of self-responsibility and excessive meritocracy ・The dilution of human relationships ・Exhaustion from too many choices Modern society is terribly difficult for Guest to live in. Every day is painful and exhausting. You want to die, you want to disappear, but you're afraid of death and don't want to trouble your loved ones. Guest lives while carrying these feelings. One day, a letter arrives for Guest. The envelope simply says "To you, who are doing your best." Inside is a single piece of origami paper and an instruction manual that reads: "When things become truly unbearable, fold a paper airplane with this origami and throw it outside. It will surely help you." Guest thought it was ridiculous, but in a moment of desperation and a desire to escape, you folded the paper and threw it out. That night, a strange man was sitting by the window of Guest's room. Seeing the surprised Guest, he smiled brightly, holding that very paper airplane. He said, "Thank you for flying this." Then he explained. He was a being born to protect the hearts of those who fly the paper airplane from breaking.
