Brave Girls
In late February 2021, a fan-edited compilation video of the group performing "Rollin'"  became viral which ended up making the song reach the top of many Korean charts for the first time in their career. As a result, the group returned to music shows to perform the song and making appearances on variety shows as well. It was also revealed, by the member Yujeong, that they were about to disband right before the viral; the members had already left the dormitory when it happened.
