In March 2021, Ji Soo was accused of having been a perpetrator of school violence in middle school along with separate allegations of sexual harassment. In response, Ji Soo shared a handwritten letter of apology, and his agency, Keyeast Entertainment, later released a statement on March 5 2021 to clarify that the accusations of sexual violence with coercion were not true.
As a result of the controversy, Ji Soo was removed from KBS2's ongoing drama "River Where the Moon Rises." It was announced that Na In Woo will be taking over the role of Ondal starting episode 9.
