New single is titled Nanja Korya (What's This?!). It will come in a regular edition, and "member" editions, each of which will contain a solo version of the aside by each member.
I'm surprisingly very okay with this? It has a very retro feel... plus Korean-ish... or something. Somehow... it's trashy, but it has the feeling of high-class trashy instead of low idol tier trashy.
