In a mixed review from IZM, writer Jung Soo-min wrote that the "oriental sound" and "repeated percussion" empathized the unique voices of all the members. Jung also added that there was one killing point in particular that stood out in the pre-chorus when the song slows down, commenting that the vocals were captivating and drew the listener in to focus. Although Jung praised Ive for trying to differentiate themselves from other competitors, they pointed out that there was a lack of strong individuality from the group's concept in comparison to other new girl groups. However, Jung noted that developing a group's identity takes time, and praised the single album, saying that overall "[this] is a debut single that exceeds expectations".[8]
