Not only fans but Korean netizens were impressed with the group's live singing skills and gathered to a popular online community to praise them.

Netizens commented, "Wendy's vocals are absolutely stunning. Powerhouse vocalist Wendy elevates the quality of the song. In the part where they all sing together, their voices blend perfectly. Throughout, the members' impromptu singing and the background chorus are enchanting. Seulgi's impromptu singing melts your ears. Irene's vocals are so good. The b-side track 'Oh Boy' is amazing. Wendy's 'Shine on Me' part really cleanses your ears. Joy is the queen of vocals. Everyone should know 'You Better Know.' The lyrics are beautiful too." "Wendy and Seulgi are trusted singers, but Irene's voice is surprisingly better than expected, and she sings well. It's not just singing passably; she sings impressively well," "I knew Joy's vocal color is good but her high tones are so much stable now," "I got chills when they sang 'Oh Boy'," "I think vocal compatibility within a group is important, like Red Velvet," and "I'm listening to this now but the five members singing together is just absolutely amazing. I love this, the 33 minutes flies by."
