Each year, BTS mark the anniversary of their 2013 debut album 2 Cool 4 Skool, which they released on June 12, 2013. Over a couple of weeks in June, the K-Pop group treat the ARMY to a series of new photos, video content and fresh music. RM rolled out this song as part of the 2021 celebrations.
Over a leisurely piano and acoustic guitar, RM talks about his feelings when he went cycling in his hometown during the COVID-19 pandemic. "For me, riding a bike always gives me a thrill, but when I put my feet on the two pedals it always feels a bit sad," the Rap Monster wrote on BTS' blog. "Whether it's because there's a lot of things that I miss... Even I don't know the reason."
He added: "Ever since I was a trainee, I always wanted to move the blurry scenery that I couldn't quite capture while riding a bicycle into a song."
Released on June 6, 2021, the song is RM's first solo material since he dropped his 2018 mixtape, Mono.
RM produced, wrote and arranged the song alongside singer-songwriter John Eun. RM previously provided backing vocals on Eun's 2020 song "Hope."
Sungsic Moon created the artwork for the release. RM has long admired the Korean artist, and asked him to be involved with his project.
