BTS star Jimin has performed his latest solo single “Who” as the musical guest on The Tonight Show Starring Jimmy Fallon on Monday night (July 22). The track is from his second solo album MUSE, which was released on July 19.

According to Deadline, Jimin is “currently participating in his mandatory military service in South Korea, having enlisted in December 2023. His appearance was filmed before his enlistment.”

The high-energy performance aired on Fallon features Jimin and a group of dancers in an artfully staged abandoned building. It begins with Jimin’s emotive vocals, accompanied by intricate choreography that complemented the song’s longing lyrics.

“We never met, but she’s all I see at night/Never mеt but she’s always on my mind,” confessed Jimin in the video, before singing: “Wanna give her thе world and so much more/Who is my heart waiting for?”

It’s not the first time Jimin has appeared on the late night show. In March last year, he made his U.S. solo debut performance of his ’80s-inspired song “Like Crazy.” He also sat down with Fallon to discuss a range of topics, including meeting President Joe Biden and keeping in touch with his BTS bandmates.

Jimin first announced his second solo album Muse back in June, with BigHit Music writing in a statement that the album would showcase his “expanded musical spectrum.”

“Following his first solo album, Face, where he sought to explore his true identity, ‘Muse’ documents his journey in search of the source of his inspiration,” the release continued.

The album also features collaborations with Loco and Sofia Carson.

Earlier this week, Jimin‘s Muse topped this week’s new music poll that features artists in various genres of music. Music fans voted in a poll published Friday (July 19) on Billboard, choosing the BTS star’s second solo album as their favorite new music release of the past week.

Muse brought in 68% of the vote on the poll, securing a notable edge ahead of new releases from Stray Kids (Ate), Joe Jonas (“Work It Out”), JADE (“Angel of My Dreams”), Childish Gambino (Bando Stone & The New World), and others.

Following 2023’s Face, which hit No. 2 on the Billboard 200, Muse continues Jimin’s experimentation. Jimin debuted solo in 2018 with “Promise” and became the first South Korean soloist to reach No. 1 on the Billboard Hot 100 with “Like Crazy” in 2023. He’s also set to release a docu-series, Are You Sure?!, with Jung Kook, chronicling their travels.
