2014–present: Solo work
In 2014, Jimin collaborated with bandmate Jung Kook on a song called "Christmas Day", a Korean rendition of Justin Bieber's "Mistletoe"; Jimin wrote the Korean lyrics himself. The two collaborated again in 2017, on a cover of Charlie Puth's "We Don't Talk Anymore" featuring Selena Gomez. Jung Kook previously released a solo version of the song in February, and the two prepared the duet as a special gift to the band's fandom, releasing it on June 2, during BTS' fourth anniversary celebrations. Teen Vogue wrote that "adding Jimin's voice to the mix makes the rendition all the more lovely", while the Canadian outlet Flare magazine stated that "it honestly might be better than the original". Elite Daily described the cover as "nothing short of flawless".
Jimin appeared on several variety shows such as Hello Counselor, Please Take Care of My Refrigerator, and God's Workplace in 2016. He also served as a special MC on domestic television music programs such as Show! Music Core and M Countdown. In December 2016, he participated in a dance duet at the KBS Song Festival with Taemin from Shinee.
On December 30, 2018, Jimin released "Promise", his first credited song as a solo artist, for free on BTS' SoundCloud page. It earned the biggest 24-hour debut in SoundCloud history with 8.5 million streams, surpassing previous record holder Drake's "Duppy Freestyle" which received 4.9 million streams, and would go on to become the most streamed song on the platform by December 2021, with over 300 million streams. Described by Billboard as a "mellow pop ballad", the song was composed by Jimin and Big Hit producer Slow Rabbit, who also produced the track, and features lyrics written by Jimin and bandmate RM. Jimin released his second solo song "Christmas Love", about his childhood memories of the holidays, on December 24, 2020. In 2022, he contributed the single "With You", a duet with Ha Sung-woon, to the soundtrack of the TvN drama Our Blues; the single was released on April 24.
In January 2023, Jimin co-wrote and featured on the single "Vibe" by Taeyang. His first official solo project since BTS announced an increased focus on individual music endeavors a year prior, the single earned Jimin his debut entry on the Billboard Hot 100 as a solo artist, at number 76. He was announced as a global ambassador for Dior later that month, and for Tiffany & Co. in March. "Promise" and "Christmas Love" were made available on streaming platforms worldwide as official singles under Jimin's name on March 6. His debut solo album Face was released on March 24. It set several chart and sales records, debuting at number one in South Korea and Japan, and number two in the US, making Jimin the highest-charting Korean solo artist of all time on the Billboard 200. The album's two singles, "Set Me Free Pt. 2" and "Like Crazy", released on March 17 and 24 respectively, both entered the Hot 100: the former debuted at number 30, while the latter debuted at number one, making Jimin the first South Korean solo artist in history to top the chart. The album's release led Jimin to become the first Korean solo artist to reach number one on the Billboard Artist 100. In May, he appeared as a featured artist, alongside Jvke and Muni Long, on the single "Angel Pt. 1" by Kodak Black and NLE Choppa, as part of the soundtrack for the film Fast X. The digital single "Closer Than This" was released on December 22, shortly after Jimin enlisted in the South Korean Army. Originally recorded during the production of Face, it is a song dedicated to the BTS fandom in gratitude for their support.
Big Hit announced an eight-episode travel reality series, Are You Sure?!, featuring Jimin and Jung Kook on July 2, 2024. Available for streaming exclusively on Disney+, the premiere episode aired August 8, with subsequent episodes following weekly through September 19. The label released Jimin's second solo album, Muse, on July 19, while he was carrying out his mandatory military service. It was supported by the singles "Smeraldo Garden Marching Band" and "Who". "Who" became Jimin's first song to debut atop both of Billboard's global charts and the longest-charting song by a Korean artist on the Billboard Hot 100 after spending 33 weeks on the chart, surpassing BTS' "Dynamite".
