What went wrong with gfriend, they were first in the runnings for NGG even before Twice debut but some where along the way they bowed to Twice and let them dominate. First rule about the entertainment industry, never buddy up or collaborate with your competitions in front of the camera because it gives room for people to compare and pick sides. And Korea chose Twice over gfriend and their company is to blame. That's why this was a very wrong move from SM, they should have know better. Or has SM just stopped caring about RV and let this happen. This most have added to the reason why RV had been on constant decline. If blinks and onces love their groups, they better hope they never collaborate and the way both groups have been acting around each other, you know their companies told them to avoid each other on camera.
