When the curtains are opened one by one, it is like the process of the truth slowly being discovered. So I decided to make a two-layer or three-layer ring curtain to surround the audience. When the audience enters this environment, they will not see any setting. As the story develops, the curtain opens and leaks out the set behind.

​

the auditorium was sunk and the eye level was level with the stage floor. It can shorten the distance between the actors and the audience without blocking the sight.
