Production
Development
In 2023, director Shin Won-ho had reportedly started working on a new project, a spin-off to Hospital Playlist (2020–2021) and contacted several actors and held auditions in secret. Later, Shin's new work was denied to be neither prequel nor spin-off of Hospital Playlist as contrast from a media report.
The series was another collaboration of Shin and writer Lee Woo-jung, who produced the Reply series and Hospital Playlist series, directed by Lee Min-soo, as well as written by Kim Song-hee, an assistant writer of Reply 1988 and Hospital Playlist. Eggiscoming managed the production.
Casting
On July 5, 2023, Go Youn-jung was reportedly cast as the female lead of Resident Playbook. She was confirmed to appear for the series two months later.
On September 20, 2023, Shin Si-ah was cast as the other female lead and confirmed it a day later. On September 22, Kang You-seok was reportedly cast as the male lead of the series and confirmed it three days later. Jung Joon-won was also cast as another male lead and confirmed his appearance three days later.
Go, Shin, Kang, Jung, along with Han Ye-ji completed the main cast line-up of the series.
Filming
In May 2023, it was reported that principal photography would begin in the second half of 2023. After two months, the filming was scheduled to start in October of that year.
Postponement
In February 2024, many doctors, residents, and interns had resigned and suspended their studies to protest a South Korean government proposal to increase medical school enrollment by 2,000 every year from 2025, setting the quota to 5,058. Due to this medical strike, the series suffered from it. tvN announced that depending on the situation the broadcast date could be delayed. In March 2024, it was reported that the series was postponed to the second half of 2024, with exact date yet to be determined. In September 2024, as the series has been delayed several times it was decided to be cancelled this year until further notice.
