"Teen Vogue" chose "What Do I Call You" as one of the "Best K-Pop Moments of 2020", with contributor Hannah Weiss writing: "With its chill soundscape and Taeyeon's airy vocals, What Do I Call You is the perfect soundtrack to close 2020. The album examines loneliness, desire and regret through a soft filter, sharing a touch of warmth to carry us through this winter". Lim Seon-hee from "IZM" compared the EP's concepts to those of  American singer Taylor Swift and its musical styles to Ariana Grande: ""What Do I Call You" is a collaboration of seasoned-ness and sincerity, with a wider range of emotions despite the method of 'removing away' without embellishment and excess. Now, no matter what genre she try, she can easily build a flagpole with her name inscribed. Beyond it all, the album becomes alive just by the deep touch of the voice that blows warm breath in the season of the bitter wind." Personnel. Credits are adapted from Melon.
