Although they look similar, they are actually completely different. Me and what's in your hollow. To change in an instant.

Even though the artist can recognize it, it cannot be shared with a third party and is somehow incomprehensible, and the strange buoyant feeling brought about by the materials of cloth and cotton further emphasizes the difference between them.
