2016: Debut with Muses Diary
After the departure of members Minha and Euaerin from Nine Muses in June 2016, Star Empire announced that the group would be making a summer comeback with a unit promotion with no further details. In early July, it was officially announced that the sub-unit would consist of four members, revealing member Gyeongree as the first official member of the sub-unit. The sub-unit debuted in early August. On July 21, it was revealed that the full line-up for the sub-group consisted of members Gyeongree (Center), Hyemi (Leader), Sojin (Rapper) and Keumjo (Main Vocal), also revealing that the song "Lip 2 Lip" would be their debut song. Nine Muses A is a shortened name for Nine Muses Amuse, meaning that the group will always make others happy and let them have a great time with their performance.
