Kangta (33) confessed that he was jealous of fellow H.O.T. member Tony An (35).

He was a guest on the July 15 episode of tvN's 'Taxi', and he confessed, "It'd be a lie if I said I wasn't jealous of Tony hyung, since his girlfriend is pretty young. But I don't think that big of an is really that much of a good thing. I like it when I can have relatable conversations with my girlfriend."

On marriage, he said, "I want to get married. But there are a lot of things I want to still do right now. But I do want to get married before I turn 38. I think I'd have done everything I want to accomplish by then."
