VIVIZ is a South Korean girl group made up of Eunha, SinB and Umji, who previously performed together in GFriend before regrouping as a trio. Untie is one of their songs, and short clips from it circulate online among K-pop fans who share favourite vocal moments, chorus hooks and dance sections. The clip works well outside a full album listen because it captures the group's bright, polished pop sound in under nine seconds. That brevity has helped it travel in fan edits, where a recognisable voice and hook matter more than a whole track.
