Career

2016–2025: Debut with Kard and military service

edit

DSP Media first revealed the upcoming debut of its new co-ed group Kard along with its members on December 5, 2016, with a card game-based concept. J.Seph was assigned a role as a "Ace" card.[6] On December 13, Kard released their first single "Oh NaNa", and officially debuted on July 19, 2017, with their first EP Hola Hola.[5] As a member of Kard, J.Seph has contributed to writing lyrics for several of the group's songs, including the EPs Way with Words and Re:.

In a February 2020 interview, J.Seph discussed his upcoming mandatory military service, stating: "I am quite anxious about serving compulsory military service, because I am afraid of being together with strangers".[7] He enlisted in the army in late 2020,[8] and was discharged in April 2022.[9] Following his discharge, J.Seph rejoined his bandmates for Kard's full-group comeback with the EP Re:, released June 22, 2022—the group's first release in nearly two years.[10] Reflecting on his return, he said: "It really feels like I'm back home. I'm really thankful to the members. I know I'm really talkative and they were always empathetic with me".[10]

2026–present: Solo debut with Spin-Off

edit

On May 16, 2026, DSP Media announced J.Seph's solo debut with his first EP, titled Spin-Off.[3] The EP was released on May 26, 2026, accompanied by the music video for its title track, "Easy".[4] J.Seph participated in writing the lyrics for all of the EP's tracks, including "Easy", "Ill", "Trippy", and "Bottoms Up".[4][11][12]
