IU's writing collaborator Kim Eana said this was her favorite IU song (to IU's surprise), saying her other love songs tend to be too 'intellectual'. It appears the more a song approaches smooth jazz the less Aaron likes it.
I really like the lyrics of this song In particular, the lyrics fit so well that I can't imagine other melody She really makes good use of various Korean postposition and expressions She has a knack for making even simple sentences pitiful and meaningful
