Hard to imagine that in almost nine years they've only released three albums.
Pf it's even worse for Angerme. Its been 13 years for them and they've also only had 3 albums. For whatever reason UP front just doesn't put much stock into Albums. (though album sales are never super high so could make sense)
and then interestingly I think about a few K-pop groups like T-ara (who's only released one album in their 13-year career) and Secret (who only managed to release one album in their 9-year career although their company mismanaged the last 4 years of it to the point that a few members had to sue )
