That group is spica and they just recently made a comeback with the song you don't love me.
If you are wondering why they have big butts in the music video, thats because they are using pregnancy pads instead of butt pads.
The thing about Spica is they are one of the most underrated girl groups in kpop. Well, thats what happens when there are too many girl groups in kpop. Fun facts about Spica is that their leader's name is Boa. Don't get angry because Unlike the other Boa, Spica's Boa actually uses her real name.
Another fact is that Lee Hyori is Spica's mentor. Fell thats all. If you like this post make sure you follow my blog and my twitter. Google + for quicker updates. annyong~^^~
