In February 2021, Jo Byeong-kyu was accused of being a former bully back in his school days, which led to a suspension of his career and investigations being made on the veracity of these allegations. In July 2021, police investigations had concluded that the allegations were fabricated and the accuser had apologised to Jo, who was set to recover his career and in talks to star in a new drama series.
Jo was judged to be a 4th-grade supplementary service in his first physical examination by the Military Manpower Administration. Jo had been diagnosed with scoliosis, but decided to apply for a re-examination. The exact timing of Cho's enlistment has not been determined, but he is expected to enlist in the second half of 2024.
