so, this is a list of all kpop girl groups that are currently active. i'm not counting the groups that already disbanded.
this is just a "guide list" for the people who want to know more about girl groups. some of them are really underrated and i'm pretty sure you've never heard about them in the past. prepare yourself, cause the list is big xD
