The program aims to show Yunho and Changmin in their everyday lives as they challenge themselves to jobs they haven’t dreamed of. Instead of focusing on their celebrity lives as popular idol group TVXQ, “72 Hours of TVXQ” will show the various aspects of the two members as they adapt to new jobs and settings. Yunho, who is known to love children, will transform into a kindergarten teacher and take charge of different classes including English, music, and physical education. Changmin, on the other hand, will try to become a restaurant chef with his outstanding cooking skills. As he experiences the intense reality of chefs in real kitchens, viewers will be presented with some new sides of his personality.
