Cute and Classy
The MV starts off a little slowly, and the chords in the beginning are strikingly typical of IU. Actually ever since the song that really made her famous, the 2011 release Good Day, almost all of her songs have started with a slow intro to a story and some slow chords with a brassy tinge. Still this release is in a rather unique genre and it plays really well with her voice. Unfortunately the song doesn't display her maturing vocals in the same way it displays her maturing image. There are a few moments where her voice really sings but not many. For the most part it's an airy cuteness of a vocal track and honestly I like the credits' instrumental version better than I like the vocal version. It just feels a bit cluttered to me with her voice so airy, when she could be singing strongly enough to create her own warm fill, like take it down an octave and then throw in some really high sweeps or something to give the track as a whole more balance. There's an awful lot going on in that high register.
I still think it's a fantastic release and I love that we get a full credits for the video.
