왕복 30분 is from GIRIBOY’s third studio album, 성인식 and was released March 17th. Though not in this song, album artists Vasco and C Jamm are featured in the music video

The song consists of a repeated extended metaphor of the relationship between him and a woman who lives “too short to drive to” but “too long to walk to.” It illustrates their awkward relationship; that they are too close with each other to be strangers but too distant to be truly comfortable.
