On December 26, Pentagon's agency, Cube Entertainment released a statement saying Hongseok who was previously attached to the wartime labour service mobilization will be discharged from his military service.
It was said, "Hongseok served with continuous treatment and counseling even throughout his military service due to panic disorder and depression symptoms with acrophobia, which he had been suffering from before. However, he has been discharged from the military based on the military's judgement and measures that his symptoms have worsened and he would not be able to balance military life and treatment."
Cube Entertainment also seeks for everyone's understanding and apologize for causing concern for such a sudden news, and they pledge to help Hongseok focus on his treatment and stabilizing his situation.
Meanwhile, Hongseok joined the army this year on May 3.
