Moon Hee Jun appeared on 'Quiz to Change the World' where he revealed that he almost became paralyzed in the lower half of his body due to an accidental fall during his H.O.T days.

He said, "I experienced an accidental fall during H.O.T's comeback concert for our fourth album 'Iyah'... While running onto the stage, I slipped on rainwater and fell off the stage."

Afterwards, it was difficult for Moon Hee Jun to walk, but he finished performing the last song "Iyah" for his fans before going to the hospital. He managed to fully recover through rehabilitation with a medical team; however, his diagnosis had revealed there was a 50% chance that his lower body could get paralyzed.

Thank goodness he fully recuperated!
