Early working title was "Oh, Naui Namjadeul" ("Oh, My Men").
Ahn Seo-hyun was cast as female lead, but was removed from the series due to disagreement between her father (who also served as her talent manager at that time) and the producers. Kim Sae-ron was offered the female lead role later, but she declined.
In April 2021, Kim Young-dae and Cho Yi-hyun joined the cast. On July 15, it was reported that Kim Young-dae has dropped out of the series. On July 23, it was officially announced that Kim Young-dae withdrew.
Based on the novel "Oh, Naui Namjadeul!" by Lee Hyun.
