And while neither Hyorin or Bora are 19, both are above 19. Which, I suppose, justifies it.
There have been two major complaints coming from netizens:
a) The '19' in 'SISTAR19' comes off as a bit too sexual.
Well, by the way Bora's gnawing on her thing of lingerie, that's clearly a good thing. If she wants to do R-rated things, I'm not going to stop her.
b) The full group only has 4 members, why create sub-groups?
I could ask the same of Ji Eun (of Secret) going solo. What makes sub-groups worse than going solo?
But at the end of the day, what we're really interested is how fappable it will be. The future looks bright boys.
