On March 3, the second and final teaser was released, showing the group dance for the song and scenes with members sitting on a sofa. The teaser shows the girls in a dark room sitting in chairs with a storm as a background. On March 3, 2017, the first teaser for the music video for 'Rollin'' was released through Brave Entertainment's website and on Brave Girls' official YouTube channel. In March 2021, in response to the song's surge in popularity after going viral, Brave Girls resumed promotions for the song. On August 11, 2018, the group released 'Rollin' (New Version)', a rearranged version of the song, as a gift to fans for their passionate support of the song over the course of the previous year and a half. The group began promotional activities for the song later that day with their first domestic television music show performance on SBS MTV's The Show, followed by appearances on MBC Music's Show Champion on March 8, Mnet's M Countdown on March 9, SBS's Inkigayo on March 12, and KBS2's Music Bank on March 24. 'Rollin'' was originally released on March 7, 2017, as the title track and lead single from Brave Girls' fourth mini album Rollin'. It soon became a nationwide hit, and achieved number one on both the Gaon Digital Chart and the K-pop Hot 100, where it remained for five and six non-consecutive weeks respectively.

Four years later, the song experienced a sudden surge in popularity when a compilation video of Brave Girls performing it for the South Korean military went viral in the country in February 2021. A rearranged version of the song titled 'Rollin' (New Version)' was released on August 11, 2018, as a thank-you to the group's fans for their support of the original version.Ī sleeper hit, 'Rollin' initially failed to chart in South Korea following its release. Written by Brave Brothers, Two Champ, and Chakun, the song has been characterized as a dance-pop track that incorporates elements of tropical house. It was released on March 7, 2017, as the lead single from the EP of the same name. ' Rollin'' ( Korean: 롤린) is a song by South Korean girl group Brave Girls.
