In the table above, the blue numbers represent the lowest ratings and the red numbers represent the highest ratings. This series aired on a cable channel/pay TV which normally has a relatively smaller audience compared to free-to-air TV/public broadcasters (KBS, SBS, MBC and EBS). Episode 10 was cut into two parts for the preparation of the extension of the show. Episodes 11 and 12 did not air as originally planned on March 12 and 13, 2018. Instead, they were aired a week later on March 19 and 20. The one-week delay was to allow time for better production. A special episode was broadcast on March 12 and 13, featuring behind-the-scenes footage and commentary by the performers.
