The brand stated, "We are looking forward to the brand's advancement with Na-Eun, whose image matches with 'CALOBYE' in that her healthy and pure image is the product of regular exercise and maintenance. We predict that her perfect body, which will convince others to want to go on a diet, as well as the infamous fandom known for selling-out leggings that A Pink wore, will play a big role in getting the brand's name out there." 

Na-Eun will be promoting various products from 'CALOBYE' ranging from health supplements to weight-control supplements, and more.
