Obviously true female empowerment doesn’t really exist in kpop due to the business culture which oppresses women, despite some improvements. But which girl group comes closer to it?
The first thing is to define empowerment. According to UrbanDictionary, Empowered means:
give (someone) the authority or power to do something.
So basically being able to act on your own. GIDLE comes to mind. SISTAR also, I guess. They seemed more free from the shackles of girl group expectations.
