Director Kim Sung-su revealed at the press conference that he was a senior in high school at the time of the Coup d'état of December Twelfth and was living in Hannam-dong, Seoul, where the incident occurred. He left his house and was walking around the neighborhood, and when he heard a gunshot from the Army Chief of Staff's official residence, he went there, but the soldiers controlled it. He was scared because he heard gunshots all night and he couldn't get close, but he was full of curiosity and questions at the time because he couldn't figure out what was going on,^[15] which led him to make this film.^[8]

Public response

This work is set about 40 years ago, but surprisingly, it was watched more by young people (20s and 30s) than middle-aged people (40s and 50s).^[17] There was even a heart rate challenge among them, where people would check their heart rate using their smartwatches while watching the movie, then take a picture of it and upload it on social media to express heightened stress or righteous anger while watching the film.^[18][19]

As this film became popular, people became interested in other works, such as 5th Republic,^[20] which dealt with the Coup d'état of December Twelfth.^[21]
