RR was a success commercially (well I assume since even though I don't follow charts, I've not heard anyone saying ("RED VELVET ARE OVER, FLOPS

") , they're not gonna get any more wins now up against that old guy and once APink/Got7 are back there's even less chance.
They're Big 3, there's no need for them promote when they already have a massive fanbase and brand power. Just be glad they're getting a rest and not being as overworked.
