The short name is DGNA not D-NA

대국남아 (Dae Guk Nam Ah) 大國男兒 (hanja)
The BOSS (The Boys of Super Space) When we say ‘The boss’ It has nothing to do with them being ‘bosses’ it’s just an abbreviation of “The Boys of Super Space”.

DGNA (short name used by int’l fans containing initials of Dae Guk Nam and Ah)
Now, the confusion on using ‘D-NA’ for short, I don’t know how it started, maybe someone translated it wrong. But, their manager corrected it on their official twitter.

That twitter is run by DGNA’s PD, which is one step below manager.

So basically he’s saying, that ‘The boss’ is their english name… not anything else, because we were using ’D-NA’.
