Prior to 'Bo go ship da' (보고싶다), another of Kim's songs, "Promise", from the album of the same name, had also been used for the popular MBC drama, Watch and Watch Again (1999), establishing Kim's staple image as a ballad singer. Critic and Writer Catherine Chan recalls the feeling surrounding the song as a 'sentimental lovers' favorite,' describing how the song 'had all the ingredients - a tender voice, lovely melody and dreamy lyrics.'
