Legal issues

On November 25, 2022, prosecutors in Suwon announced that O had been indicted on sexual misconduct charges relating to an incident in which he allegedly sexually assaulted a woman in 2017. He was accused of various cases of sexual misconduct in which he had inappropriately hugged, made lewd comments towards, laid in the same bed with, and kissed the alleged victim across multiple incidents. Although he was charged in 2017, he was not indicted until 2022. During his trial in February 2024, the prosecution sought a one-year jail term for O, who denied the charges.
