This wouldn’t stop the delulu fans from shipping themselves with them but I think they would also get heat from knetz.
For idol groups the fan service is part of their “job description “. It has been since the beginning. I’m sure they would get people who would say “Then why are you an idol group? “ “So cold” or “Rude” or something along the lines.
Well, Yeah.
But, I don't there is a thing called "Job Description" for idols....
