Hospital Playlist stars Ahn Eun-jin, Jung Kyung-ho, and more made their appearances in the ongoing tvN drama Resident Playbook featuring Go Youn-jung and Kang You-seok. Hospital Playlist, a drama about wise surgeons, became one of the most loved K-dramas due to its storytelling and the characters when it first aired in 2020 on tvN and Netflix.
The second season of the drama also became a success, opening paths for the spin-off Resident Playbook, telling the stories of rookie residents. The two series are interconnected to each other, as the characters share the same backdrop of Yulje Medical Center but different branches.
Viewers and fans who have been missing Hospital Playlist may get glimpses of the characters in Resident Playbook as the actors are set to make a cameo. In Resident Playbook episode 2, Ahn Eun-jin, who played Chu Min-ah, reprised her character.

Ahn Eun-jin as Chu Min-ah in episode 2:
Chu Min-ah, played by Ahn Eun-jin, saw Oh Yi-young with a huge bag, assuming that she was running away because they had observed several residents quit their jobs due to the work pressure. Chu Min-ah lured her in for a coffee break and spoke about her days as a resident. She gave her an important document and asked her to deliver it to chief resident Ku Do-won (Jung Joon-won) at the Jongno Branch.
She later called Ku Do-won to take care of Oh Yi-young so she would not quit. Chu Min-ah was then seen talking to a person on a phone call in a lovey-dovey manner, confirming that she was married to Yang Seok-hyung (Kim Dae-myung).
Ha Yoon-kyung & Moon Tae-yu in episode 3:
In Resident Playbook episode 3, it was shown that Yong Seok-min, played by Moon Tae-yu, became a professor while Heo Seon-bin, depicted by Ha Yoon-kyung, was writing research papers with Choi Seong-hwa (Jeon Mi-do). Yong Seok-min was seen taking glances over someone standing in the back of an elevator, and due to this, Pyo Nam-kyung (Shin Si-ah) thought he was looking at her.
Pyo Nam-kyung concluded that Yong Seok-min liked him. However, as the people got off the elevator, Yong Seok-min went to the back and held Heo Seon-bin, who told him to stop looking at her that way or else people might get the wrong idea.
Jung Kyung-ho in episode 4:
Jung Kyung-ho, popular for his role as CS surgeon Kim Jun-wan, was called to the Jongno branch for a case study by Professor Seo Jung-min (Lee Bo-ryun). Oh Yi-young was asked to report to him, but she kept making mistakes and got scolded by Kim Jun-wan. He said she reminded him of someone who keeps making mistakes and, at the same time, gets a call from Do Jae-hak, played by Jung Moon-sung.
Kim Jun-wan and Do Jae-hak showed their unending bickering once again in Resident Playbook. Later, Kim Jun-wan showed his support to Seo, who could not save the baby for the second time when she addressed the same to the mother.
Yoo Yeon-seok in episode 5

Ahn Jeong-won (depicted by Yoo Yeon-seok), the warm-hearted cheapskate pediatric surgeon from Hospital Playlist, appeared in Resident Playbook briefly. During the team dinner, Oh Yi-young accidentally sat at his table and ate from his plate while she was drunk.
Meanwhile, Ahn Jeong-won is known for secretly helping patients with financial and other support. He met Oh Yi-young again, who had a heartbreaking conversation with Hye-min, the daughter of Ms. Ha, the patient who is in critical condition and may not make it alive. Ahn Jeong-won had come to take Hye-min as he decided to provide her with the required support following Ms. Ha's passing.
Bae Hyun-sung in episode 6

Jang Hong-do played by Bae Hyun-sung visited the Jongno branch and bumped into Um Jae-il (Kang You-seok). Notably, Jang Hong-do chose CS as his field and is now a senior resident. Um Jae-il told him about the first child he assisted in delivering and how he was a part of the patient's journey from checking it through the ultrasound. Um Jae-il asked him a question, and Jang Hong-do explained it to him.
Jang Hong-do reminded Um Jae-il that they learned this part during medical school, and he forgot about it so soon. Um Jae-il was in a tight spot as Jang Hong-do kept asking him questions, and he could not respond. This scene referenced Kim Jun-wan asking Jang Hong-do difficult questions during the internship, and him not knowing the answers to them. Jang Hong-do then revealed that he was just kidding.
