“치리사일사팔 (724148)” is backed by a bass-heavy beat with light-hearted delivery, although the core themes of the lyrics are not as whimsical as Suga sets them up to be.

#724 is the bus Suga used to ride from his home to and from his small music production job in Daegu. It’s symbolic of his struggle at the time: he’d often have to choose between going hungry or walking home due to how little he was paid.

#148 is the bus he used to ride from his trainee dorm in Apgujeong in Seoul to and from school and work. It represents his move from a small town with limited prospects, to the big city where he worked tirelessly as a trainee to fulfill his dreams of becoming a musical artist.
