This work is called ‘Really’. It means that something is true or not. Whether what people see with their eyes is true or false; a question mark causes the audience to think. First, the protagonist of this work is a blue-green doll, which is made up of two circles. The chubby doll makes the viewers have a great impression of this doll, which is cute. The whole story is caused by this doll. This work is mainly a narrative, a story that the protagonist is 2D at the beginning. In the 2D protagonist's eyes, the world is 1D; everything is a line. After the transition to the 3D world, human perspective can see the hero protagonist; the hero was out of the original human-viewed 2D world into a 3D world. The hero, although this time is 3D, but the human sees that the hero is still 2D. Because the human is three-dimensional, they watch all the things that will also be 3D. In the end, the hero protagonist escapes the human capture: leaving the suspense for the whole story, but also raising the question of whether there is a thinking world outside of human beings' world and watching human beings; and the watchers are in a 4-dimensional space or even higher dimensional world. This is the story line of the whole work.
