People say you make your best friends in school and for these two actors they made best friends in School for sure haha. School 2013 to be exact, the KBS drama series that got revived with the 2013 version and spawned three more iterations with Who are You: School 2015, School 2017, and the latest School 2021. Kim Woo Bin and Lee Jong Seok parlayed their school yard competition and friendship to each reach new career breakouts thanks to this drama and it’s so heartwarming to see their friendship still going strong after military service and illness and lots and lots of successful movies and dramas between them.
