The "Reply" drama series has three shows to date: "Reply 1997," "Reply 1994," and "Reply 1988." Each show is set during a certain era (1997, 1994, 1988, respectively).
This franchise — created by star producer and writer duo Shin Won-ho and Lee Woo-Jung — has garnered a large fanbase.
All three shows are similar to "How I Met Your Mother" in the sense that audiences will keep guessing which relationships will and won't eventually work out. And while it's very fun to guess who will fall in love with each other, the focus of the series is on family, community, and growing up.
Although each show is similar in terms of theme, style, and format, each season has a different set of characters and new storylines.
"It's a very unique approach to a television series," Hong told Insider. "The concept of the show is maintained throughout, but it's not that all of the shows are led by the same characters."
