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.
