what exactly is the hold up with min heejin's group? (from ador)

ador's company accounts are live, min heejin was on tv promoting the fact that the group is complete and she's been sitting on the debut song for like 2 years, and yet they're still not teasing the debut or the members in any way? its projected that the group is debuting in the first half of the year, so since jan debut is pretty much ruled out now, that leaves 5 months. i doubt the group will be debuting when bts comes back (which will likely also be first half of the year) so now we're down to only 4 potential debut months. i wish they would at least tease the members and get people hyped about the group. the radio silence is deafening.
