The concept in this work is feeling signs of others who had been there with the body and following them.

​

 I believe that people can feel the other's existence that is not there from only sounds, smells, and air sway as well. I tried to express the image of the absent person strongly by tracing the slight trace repeatedly. In this work, I used a fan noise and smell of eating an orange as trace clues to represent that a person who would have been, or might come to the room.
