Kangta of H.O.T fame revealed why he's afraid of water on the May 27th installment of JTBC's 'Suddenly Heroes'.

On the show, Lee Jae Hoon suggested Kangta, Jung Jun Ha, KCM, and Joo Woo Jae clean up ocean garbage, saying, "When I was diving, I saw so much trash."

The suggestion made Kangta freeze up, and he shared, "When I was 3 or 4, I almost drowned. My father saved me with difficulty. I don't remember it, but strangely, I have a phobia. Even if the water level reaches my neck, I freeze and panic."

Lee Jae Hoon responded he should overcome his fears, and Kangta agreed, even wearing scuba gear to practice breathing.
