Do It Again comes from The Story Begins, the 2015 debut mini album by South Korean girl group TWICE, formed under JYP Entertainment. Momo, one of the group's Japanese members, handles dance and rap roles, and her verse became a favourite section for fans known as ONCE. As TWICE grew into one of K-pop's most streamed acts, short clips of standout rap and dance breaks circulated widely on fan edits and social platforms, keeping this early track in regular rotation long after its release.
