Kyung Li first compared concepts, explaining, "Unlike Nine Muses, Nine Muses A captures bright, bouncy charms found in people in their 20's. It's a concept that I've always wanted to try ever since I was young."
She continued, "Nine Muses emphasizes sexy, but Nine Muses A has both sexy and fresh. With that in mind, I think we will be able to radiate more youthful charms. And since there are only 4 members [in the subunit], I think each person will be able to show more of their individual charms and eventually, we will become energizers for full Nine Muses promotions."
