Their song "Don't Touch Me," written by Rado (one half of the famous songwriting duo Black Eyed Pilseung), has completely dominated the Korean music charts since its release a week ago and was the first song that managed to get a Perfect All-Kill since BTS's mega-hit "Dynamite."

What makes this historic feat even more impressive is the fact that the group doesn't have a fandom. Instead, Refund Sisters has a huge following from the general public after being created on the TV-show "Hangout With Yoo." The group, led by K-Pop legend Lee Hyori, is the follow-up group to SSAK3, who dominated the music charts this summer. "Don't Touch Me" was heavily anticipated by the viewers, and it only helped that Rado's song turned out to be really, really good.
