Park Ji-min (Korean: 박지민) was born on October 13, 1995 in Geumjeong District, Busan, South Korea. On June 13, 2013, Jimin made his debut as a member of BTS with the release of the single "No More Dream". In the group, Jimin holds the position of vocalist and dancer. Under BTS, he has released three solo songs: "Lie", "Serendipity", and "Filter". "Lie" was released in 2016, as part of the group's second Korean studio album, Wings. It was described as stunning and dramatic, conveying dark undertones and emotions that helped reflect the overall concept of the album. In contrast, "Serendipity", released on the Love Yourself: Her (2017) extended play (EP), was soft and sensual, unraveling the joy, conviction, and curiosity of love. "Filter", from the group's 2020 studio album, Map of the Soul: 7, was very different from its predecessor, with a distinct Latin pop-esque flair and lyrics that reflected on the different sides of himself that Jimin shows to the world and those around him. "Serendipity" and "Lie" both surpassed fifty million streams on Spotify in 2018, followed shortly thereafter by the former's full length version from BTS' Love Yourself: Answer (2018) compilation album, which achieved the milestone in early 2019. With this, Jimin set a new record as the only Korean artist to have three solo tracks accumulate over 50 million streams each—previously Psy was the only Korean artist to ever cross the 50 million streams mark with "Gangnam Style" (2012) and "Gentleman" (2013). Both songs were also the only solos by a BTS member included in the Official Chart Company's list of the top 20 most streamed BTS songs in the United Kingdom as of October 2018, ranking at number 17 and 19 respectively. In April 2019, the list was expanded to reflect the top 40, and both tracks ranked at numbers 18 and 20 respectively, the highest of five solo songs included that year.

On June 14, 2019, J-Hope, together with fellow BTS member V, collaborated with Zara Larsson on a soundtrack called A Brand New Day for a mobile game BTS World. J-Hope released his first solo mixtape, Hope World, worldwide on March 1, 2018. It was accompanied by a music video for the lead single "Daydream". A music video for the B-side "Airplane" was later released on March 6. The mixtape debuted at number 63 and peaked at number 38 on the Billboard 200, making him the highest charting Korean solo act on the chart up to that point. Hope World also peaked at number 35 on the Canadian Albums chart, and number 19 on the US Top Rap Albums chart. Three mixtape tracks, "Daydream", "Hope World", and "Hangsang", charted on the World Digital Songs Chart, at number 3, 16, and 24 respectively. The following week, the tracks rose to number 1, 6, and 11, with three additional tracks off of Hope World, "Airplane", "Base Line", and "P.O.P (Piece of Peace) pt. 1" arriving on the chart at number 5, 6, and 12, respectively. "Daydream" peaking atop the chart made J-Hope one of only ten Korean artists, including BTS, to reach number one. The success of his solo debut lead him to rank at number 3 on the Emerging Artists Chart, and 97 on the Artist 100 Chart for the week of March 10, later peaking at number 91 for the week of March 17. He is the fifth Korean artist, and the second Korean soloist after Psy, to place on the Artist 100. The mixtape charted in ten countries worldwide, with "Daydream" charting in three. It was ranked at number 5 on Billboard magazine's year-end World Albums Chart.
