Sechskies' Kim Jae Duk and Tony An confessed they were both rivals in the past. The H.O.T member explained, "The rivalry between fandoms were quite intense. There's a particular scene in 'Reply 1997' where fans break out into a fight and I personally witnessed such an incident in real life."
Kim Jae Duk commented, "This fan came over to me and said, 'Oppa, I fought three H.O.T fans and I won. This may seem a bit graphic but I think she was bleeding. I remember telling her she did a good job nonetheless. I felt a great sense of pride back then."
