Reply 1997 is a 2012 South Korean television series that centers on the lives of five friends in Busan, as the timeline moves back and forth between their past as 18-year-old high schoolers in 1997 and their present as 33-year-olds at their high school reunion dinner in 2012, where one couple will announce that they're getting married. The coming-of-age drama also examines 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 blossoming. It originally aired live on cable channel tvN in 16 episodes. But due to its popularity, the 15th and 16th episodes were also aired simultaneously on Mnet, OCN, O'live, Ongamenet and OnStyle. The last episode recorded the highest ratings at the time for a Korean cable drama, and the series has garnered praise from audiences and critics for being well-researched, refreshing, genuine, and full of humor and heart.
