Critical reception
Yoo Ji-hee from Daily Sports expressed that the group failed to establish a clear identity apart from their labelmate seniors 2NE1 and Blackpink, and wrote how the song evokes "a familiar taste, but it's not enough to really grab you." Rhian Daily from NME rated the song two out of five stars, calling it "a tired formula" with "lazy songwriting" and commented "Even in the moments that are clearly designed to be the track’s earworm moments, it feels weak and leaves no lasting impression."
