Hospital Playlist

One of the five titular doctors and best friends in Hospital Playlist is identified as being gay. This character's sexual orientation is a part of their identity within the show, contributing to the diversity of the main cast. While specific plotlines explicitly detailing their coming out or romantic relationships beyond this identification are not highlighted as central, their presence as a gay character among the main five is confirmed.

The show portrays numerous medical emergencies and complex surgical scenes, which often involve realistic depictions of blood and severe injuries in a clinical context, such as organ transplants or emergency trauma cases. Patient deaths, particularly of children, are recurrent and depicted with significant emotional impact, affecting both the families and the medical staff, especially Dr. Ahn Jeong-won. Additionally, there is an instance in Season 1 where Jang Gyeo-ul reacts to and pursues a father who physically disciplined his child, suggesting the presence or strong reference to child corporal punishment or implied domestic violence.

The drama features various romantic pairings among the main doctors and supporting characters. These relationships include romantic scenes with kissing, such as Ahn Jeong-won and Jang Gyeo-ul's kiss at the end of Season 1, and Lee Ik-jun and Chae Song-hwa's kiss in Season 2. The series also addresses mature relationship themes like divorce and marital infidelity. For example, Lee Ik-jun goes through a divorce after his wife has an affair, and Yang Seok-hyeong's family history includes his father's infidelity, which is discussed as a past event.

The five doctor friends are often shown drinking alcohol together, such as during their regular band practice sessions or informal social gatherings after work hours. In one scene, a character's brother, who is a priest, suggests inviting the struggling Dr. Ahn Jeong-won out for a drink to help him confide, indicating social drinking as a common coping mechanism.

The hospital setting inherently involves intense content. The show regularly features urgent medical crises in the emergency room, tense moments during surgeries, and difficult discussions with families about grim prognoses. The deaths of patients, particularly young children under the care of Dr. Ahn Jeong-won, are portrayed with considerable emotional weight, leading to scenes of profound grief and distress for characters and viewers. While these scenes are emotionally impactful, they are not presented with jump scares or horror elements but rather with a focus on the human drama of medicine.

Ahn Jeong-won is a devout Catholic from a family where all his older siblings are priests or nuns, and he himself contemplates entering the priesthood, making Christian faith a significant aspect of his character. Some viewers have expressed concerns about perceived 'soft anti-Catholic bigotry,' citing scenes such as Jeong-won blaming God for a patient's death or his choice to remove rosaries and bibles when pursuing a relationship, implying a conflict between faith and love that some found problematic. Conversely, other Christian viewers found the subtle incorporation of religious symbolism and Jeong-won's 'pastoral figure' portrayal to be inspiring and aligned with Christian values.
