Heehyun (Cathy) of DIA recently participated in ‘Unpretty Rapstar 3‘, and while her diss against SuperBee on the show didn’t earn her a permanent place on the program, it did gain attention at least.
That basically explains the whole situation.
So Heehyun’s angle is righteous when it comes to this, and there aren’t any lies in her lyrics, which is why it’s receiving positive feedback. However, I do wonder what would happen if SuperBee replied given that he’ll diss anybody for attention. I dunno, but I want it to happen so we can find out.
