The music video for the song also set a record for the highest number of views for a K-pop debut within its first 24 hours. Their rapid ascent continued throughout 2019, as the group became the first K-pop girl group to achieve a “Rookie Grand Slam,” securing all five major Rookie of the Year awards in South Korea.
