SEE ALSO: Tony An reveals he and Girl's Day's Hyeri tried to break up before because of their 16-year age difference

On the October 26th broadcast of MBC's 'Quiz to Change the World', special MC 2AM's Seulong complimented Tony An as he told him, "I think it's really impressive... Because there is a generation gap of 16 years." Tony An shared, "I hardly noticed a generation gap because ever since I started talking with her, she always talked a lot about g.o.d. Not TVXQ, but more so about the generation of g.o.d to the point that sometimes, I think that she knows more about my generation than I do."

MC Lee Hwi Jae added, "I know Tony well because we're in the same agency. When that scandal first came out, both agencies went hectic. The person who was most calm in the situation was Hyeri. She told him, 'Oppa, don't worry.' Did she call you, 'oppa', from the start or did she call you, 'sunbaenim' or 'teacher'?"

Tony An shared, "She called me, sunbaenim and daesunbaenim. Now she calls me, oppa... What I like most about her is that we can converse well with each other. Because from the start, we conversed well and our way of thinking is similar."

Fellow H.O.T member Moon Hee Jun shared, "There is something I am really jealous of. We recently filmed 'Handsome Boys of the 20th Century' and we were performing the choreography and in the middle, there was a solo dance which I did. I met Hyeri later at another broadcast. But upon seeing each other, Hyeri, said, 'Eumm?', to me. So I greeted her back with, 'Eumm'. I asked her why. Hyeri replied, 'Why did you do all the handsome solo choreography yourself? My oppa also dances well.' I was really envious."

Tony An shared, "To be honest, we had a sunbae-hoobae relationship, but I thought maybe we had interest in each other. But suddenly, I thought to myself one day that maybe this is wrong because we have such a big age gap. I thought that this was wrong so I told her, 'I think it would be good if we don't see each other again. It would be good if we don't contact each other.' I was sad but that's how I really felt. I told her, 'I don't think this is right. That's how I think.' But she said something that sealed the deal", which left all of the guests incredibly curious. But Tony An kept his lips sealed and told the viewers, "To be continued next week", making them laugh out loud at his cliffhanger.
