BigHit earlier said "Happy," scheduled for release on November 15, would contain six songs.

The album has been described as "Jin's heartfelt invitation for fans to join him on his journey to discover happiness."

"Happy" marks Jin's first solo album, though the 31-year-old has previously released tracks like "Super Tuna" and "The Astronaut," and contributed to K-drama soundtracks.

In June, Jin, whose full name is Kim Seok-jin, became the first of BTS' seven members to complete his military service.

Since his discharge, he has been active in various roles, including serving as a torchbearer for South Korea at the Paris Olympics, launching his own online variety show "Run Jin," and joining the cast of Netflix's upcoming variety show "Kian's Bizzare B&B."
