WTH HAPPWND WITH PINK DOLLS

DOES ANYONE REMEMBER PINK DOLLS? They were a k-pop girl group like in 2000 (idk) I remember when I met them it was because of the movie “White: the melody of death (2011)” but at the time I saw the movie if there was information about them on the internet BUT NOW NOT 😭😭 I'M COMPLETELY SURE I SEEN INTERVIEWS OR SOMETHING LIKE THAT BECAUSE I REMEMBER SOME OF THEM DIED (I DON'T EVEN KNOW IF IT'S TRUE WHAT I REMEMBER) AND IDK ANYONE REMEMBER THAT THEY DID EXIST OR AM I CRAZY? ?????????
