Singer Tony An talked about his love life on the November 11 airing of SBS's 'Our Hatable Children.'

When asked, "How much did you date when in H.O.T?"  his pupils and lips shook from surprise.  Kim Jae Duk said, "Did you have a girlfriend you even considered marrying?" and Tony An replied, "There was.  My mother liked her quite a lot.  My mother probably wants me to get married and have a child, but she doesn't show it."
