This work is made with acrylic paint and pen on foamed polystyrene. The framework is made of wood and polystyrene. The work has a puzzle-like appearance, based on internal and abstract image drawings and boundaries - in-between and fitted together. Lines made by playing dripping acrylic paint and string. Letters are concave on the border of a flat surface. They remain in the work as marks and phenomena created by dripping, playing, and brush pressure. Margins of the ground remain in the work as gaps. The large and small rings are the borders of colors marked with marker pens. The fine dots on the surface are acrylic spray paint. In the process of creating this work, I had a change of heart and mind, and felt the ambiguity and connection between the inside and the outside, which led me to feel things such as subjectivity and objectivity, room and territory. I believe that this leads to an image of refreshment and relaxation between the outdoors and the indoors. The material polystyrene foam is light, soft, and delicate, making it difficult to handle, but together with the wrapping, it gives the work a soft impression. Also, the countless air bubbles inside the structure are interesting from a spatial point of view.
