K.O.B.A

KOBA for its acronym in English (Kpoppis obsessed with BTS and Army) is how the second fandom of BTS and Army are known, because they are always aware of everything we do, and they do not accept that BTS WAS THE ONE WHO PAVED THE ROAD FOR YOUR FAVS, AND THAT ARMY IS AND WILL BE THE STANDARD.

The K.O.B.A is so aware of BTS and Army that they already know about the new version of the boys album. They really secretly love us.
