“Spring Day” is BTS’ single from their 2017 album “You Never Walk Alone” it was a repackage of their second Korean-language studio album, Wings (2016). The song was written by “Hitman” Bang, RM, Suga, Adora, Arlissa Ruppert, Peter Ibsen, and its producer Pdogg. “Spring Day” is the longest-charting song on Melon’s digital chart to date.

Speaking about the concept and meaning behind “Spring Day” during a V Live broadcast, RM stated that he wrote the lyrics when thinking of his middle and high-school mates, from whom he hadn’t heard in a long time. RM compared the song’s mood to that of the band’s 2015 singles, “I Need U” and “Run”. Lyrically, the song uses a seasonal metaphor to compare the longing and separation from loved ones to “internal winter.”
