During a V Live track-by-track review of his mixtape from March 1, 2018, J-Hope explained how he wasn't singing the blues, but was expressing his desire to go back to all the good times under the blue sky. "I made this song three years ago, everyone. I think I made it after '1 VERSE.' At that time … I think I was really into something blue, some blue vibe," he said. "I liked the wind and the sky. I want to go back in time when I was so clueless. The blue sky and wind and full of good memories. I want to go back to the 'Blue Side.' That’s what this song is about."
Now, three years later, J-Hope shared his most recent thoughts about his reworked version of the song on Bangtan Blog. "I wanted to show that I am getting a little bit of musical maturity, and furthermore, it was released with a strong desire to continue to challenge, develop, and come back with growth," he wrote.
"Blue Side" is the dancer-rapper-vocalist's first solo release since 2019's "Chicken Noodle Soup," featuring with Becky G, which made him the first BTS member to earn a Billboard Hot 100 hit on his own. Hope World's debut on the Billboard 200 made him the highest-charting K-pop solo act on the album tally at the time.
