In the world of K-Pop, idols seem to come and go in many within many groups.
And in some extreme cases, some groups are only left with one idol. Of course, it wouldn't make sense to call them a group at that point and it definitely signals instability.
Below are female idols who are the last remaining member of their group.
WooHee (Dal Shabet)
Currently in Uni.T after making it as a winning finalist on KBS2's 'The Unit', WooHee joined Dal Shabet back in 2012 when Viki left the group.
YoungJi joined KARA back in 2014. Unfortunately, the rest of the Kara members (Hara, GyuRi, SeungYeon) left once their contracts with DSP Entertainment expired.
HaeRyung was also a former member of EXID, part of the original six-member lineup. After the departure of HyeYeon, she is now the last remaining member of BESTIE.
Now that Jun HyoSung has burned bridges with TS Entertainment, Hana is all by herself in the agency's girl group Secret. While TS Entertainment has stated they will support Hana as a solo artist, fans have yet to see that happening any time soon.
