Reply 1997 is a 2012 South Korean television series and the first installment of the Reply anthology series. It centers on the lives of six friends in Busan as the timeline moves back and forth between their past selves as 18-year-old high schoolers in 1997 and their present selves as 33-year-olds at their high school reunion dinner in 2012 where one couple will announce that they're getting married. It portrays the extreme fan culture that emerged in the 1990s when first generation idol groups such as H.O.T. and Sechs Kies took center stage and K-pop was just beginning to blossom.
