This trio formed by 9Muses's Kyungri and Sojin (she was meant to become a member of 9Muses later) and ZE:A's Kevin that released one and only song and MV back in 2014.
I liked this song a lot!
It was on Kpop's sexy concept era, and many accused them of copying Troublemaker (a duo formed by former 4minute's Hyuna and former B2ST's Jang Hyunseung), but none of this made sense actually, and it caused a fuss on Kpop community due to its daring teaser pictures.
Some found the MV risqué, some felt underwhelmed 'cause they expected the MV to be a lot more "nasty", but anyway, many enjoyed it.
They performed the song live on many music shows.
And have a dance practice video of it.
Unfortunately, as I mentioned, the group only released this song and never came back.
