The Ktown4u Coex store is themed Journey to the New Kpop Universe and represents a space journey toward the Ktown4u planet, the landmark of Kpop. It is a process of traveling freely between stars, getting closer to one's star. The design boldly uses primitive and simple materials such as metal, lighting, and stone spray, while incorporating the geometric meanings of curves and straight lines to express an elemental cosmic space. The movable walls and furniture create various spatial transformations, allowing global fans to have experiences.

Design can be defined as a culture that goes beyond the pursuit of external beauty, a concept that is not unfamiliar, as it is something many people discuss and resonate with. For 21gram, design is not defined by temporal divisions such as past or present, but by the historical discoveries and humanistic records embedded in places and cultures. 21gram is a design group made up of individuals with diverse personalities, all of whom are more interested in the culture experienced through the senses than in the form or concept of objects, evolving through opinions and discussions. Design is the process and result of the intersection of our perspectives and aesthetic opinions.
