Hwasu Yoo's work began when she realized that her complexes, her negativity, were constantly bothering her or floating around, giving her anxiety or a state of wanting to escape, and she had a desire to anchor them somewhere. Through the act of 'painting' she make a transition from the real to the unreal. It is manifested by breaking away from all the circumstances that make up her life, such as repetitive routines, habitual behaviors, and absurd situations, and creating a new world. The feelings and images surrounding the materials, which are based on personal experience or the real world, are subjectively interpreted and transformed to create an unreal virtual world on canvas. Her work is mainly based on a square or circular canvas as a medium and attempts to create a 'virtual world' as a subjective expression, fiction and fantasy through the act of 'drawing' and 'fabric' on top of it. Her work is an imaginary space and aims for a utopia, as it tells the story of people who are tired of the many systems and concepts in the real world and seek fun by disguising themselves as boys and girls. The flowers, horses, and children are devices to express her utopia. The children are each collecting horses, which symbolize the freedom of floating, and they travel from place to place for fun. The horses are disguising themselves from their surroundings and trying to avoid being caught. The transition and longing for another world is seen as a kind of escapist psychology, and the escape from reality is achieved by psychologically enlarging the self and shrinking the real external world through images found in the psychological state of dissatisfaction with reality. In addition, desires that are unfulfilled or difficult to achieve in reality can be realized in the imagination. It was hoped that this would generate thoughts that could cross the line between reality and unreality. The 'virtual world' is revealed as a non-existent landscape and narcissistic fantasy. The wildflowers, plants, grasses, and flowers on the canvas are only artificial and lifeless beauty. Spread flat on the canvas, they are the shells of things, representing a world that exists on the surface of the painting but has no substance.
