The white cat who plays the role of Hong Jo in cat form is named Baegi.
Early working title of the series is Man Who Bakes Bread (Sikppang gumneun namja). It was originally planned to air on cable channel tvN in the first half of 2019, and the lead roles were offered to Yook Sung-jae and Park Eun-bin, but both declined.
In order to circumvent Korean laws that prevent commercial breaks in the middle of an episode, what would previously have been aired as single 70 minute episodes are now being repackaged as two 35 minute episodes, with two episodes being shown each night with a commercial break between the two.
The first script reading took place in October 2019 at KBS Annex Broadcasting Station in Yeouido, South Korea.
Park Eun-bin became the female lead in the 2019-2020 SBS TV Friday-Saturday drama Hot Stove League, which was produced by the same production company behind Meow, the Secret Boy.
