The premise to this is pretty weak but I like idol/kpop yuri so I'm seated
It is weak, and yet there's something oddly realistic about that. I have the impression that in the idol business they do a lot of absurd things for really stupid fan-management reasons.
It's surprising that there aren't many yuri K-pop/idol manhwas out there. This one was really good! Since it's posted on Postype rather than Lezhin, I don't think it'll lean heavily into sexual content and will likely focus more on the plot.
