Nine Muses' original comeback was supposed to be in July (stated by Erin on 140402 ShimShimTaPa) and they've been preparing for their comeback since May/June-ish (Hyemi vaguely alluded to the comeback concept on 140603 ShimShimTaPa) so it really does seem that the delay in their comeback is because of the lineup still being tinkered with. :/

Ahead of their scheduled comeback, girlgroup Nine Muses is having repeated difficulties with recruiting new members.With the official announcement of "graduation", Lee Sem and Eunji left the Nine Muses team in January. Sera, too, left the group when her contract with Star Empire expired in June. Following these events, Nine Muses is now a 6-membered group comprised of the remaining Hyuna, Euaerin, Minha, Hyemi, Kyungri, and Sungah.With regards to this, Star Empire has stated that the present situation is. However, until a new member is able to be added, there are plenty of other factors that need to be taken into consideration andAs for the fans who passionately support Nine Muses, they are mostly of the opinion that "There is no need for any new members". Additionally, it cannot be ignored that there is the possibility that there will be a clash of roles with existing members. Yet, the agency’s viewpoint is that taking risks with chances is inevitable; even amidst uncertain circumstances,Presently, the preferred number of reserve members is 2. Whether in the areas of dancing or singing, they will have talents unique to themselves, and the agency is convinced that it will be an upgrade to the team. Furthermore,. However, as the number of passionate fans has grown large in the 4 years since the group’s debut, it is necessary to take time to persuade these fans of the situation. Previously in the situation of KARA, following the departure of Nicole and Kang Jiyoung and the announcement of recruiting new members, there was backlash from a portion of fans. Even so, with the scouting of an outstanding member who had the looks and talent, the objections also ceased - this case merits consideration from others in the entertainment industry.
