If you are wearing a doll mask alone on the street, you will stand out and be remembered well by everyone. However, no one knows who is inside the doll mask. By not directly revealing the main character's true appearance, I further expressed the social deprivation of the main character. The protagonist creates something in common with dogs by attaching dog hairs to his doll mask, but is increasingly isolated in human society. The dogs that the protagonist felt bonded to were perfectly painted, but those passing by expressed them only with silhouettes, further highlighting that point. However, wandering dogs were also living on the meals given by the villagers, and when the main character knocked down the villagers, who were their social connections, the dogs rushed to the main character and bit off the dog's hair attached to the main character's doll. The protagonist is kicked out of both the dog's society and the human society. This is because the two societies were the same society in a big way. The next day, a part-timer is working on the street where the main character worked. Just as the protagonist handed out, they are distributing telecom flyers with the words asking for connection with each other. However, since you can't see the person inside the doll mask, you don't know whether the main character has returned or a new part-timer has come.
