Almost 'Reply 1997'-style, his statements are like a blast to the past!  Moon Hee Jun talked about the fan club during H.O.T days.  After the boys had one of their first concerts in Jamsil Stadium during their prime era, there were fans who created a ban from leaving the venue early.  Moon Hee Jun said the most memorable fans out of those were Fin.K.L members.

He said, "There were always fans waiting in front of the building during our H.O.T days, but among those, there were pre-debut members of Fin.K.L.  Out of all the fans, there were two who stood out appearance-wise and those two turned out to be [Fin.K.L.'s] Lee Hyori and Lee Jin."

He also mentioned another fan who became a Fin.K.L member, Ohk Joo Hyun.  He said, "Ohk Joo Hyun made us flustered with her vocals, which were like no other.  Even Lee Soo Man remembers that."
