History Series / HospitalPlaylist

* ThankingTheViewer: After a montage showing behind-the-scenes production photos, the series ends in episode 2.12 with a message saying "Thank you for watching ''Hospital Playlist''."

* NoPeriodsPeriod: Gyu-wool takes some medicine for menstrual cramps. She winds up having a nasty allergic reaction that gets her hospitalized in the very hospital where she works.
* Music/PachelbelsCanon: In a flashback to 1999 in episode 1.4, Seok-hyung demonstrates his proficiency on keyboards to the rest of the band by playing Pachelbel's Canon. Then, in a scene 20 years later, the whole FiveManBand plays Pachelbel's Canon together in an up-tempo rock arrangement.

* TheCameo:

* IllGirl:
** In the first episode Jung-won is treating a little girl who has a serious heart defect.
** The first episode of Season 2 has Jung-won treating a little girl named Chae-eun who has received a liver transplant, and believes she will soon die.

** Episode 2.10 has Gyu-wool's brother show up, and they have a conversation which reveals why their mother is in bad health and Gyu-wool is worried about her. It seems that their father is an abusive alcoholic who, when he's drunk, beats their mother so badly that she often has to be hospitalized. The brother's impending marriage has been canceled by his girlfriend's family. A tearful Gyu-wool confesses the whole story to Jong-won, and naturally he is supportive.

* CockADoodleDawn: The series of flashbacks showing Jung-won sobbing on an annual basis to his brother about how being a doctor is hard, and he wants to quit, are made even funnier by the sound of a rooster crowing the dawn each time. In the big city of Seoul.

* Jung-won, pediatrician. He comes from money; in fact, his family runs the Yulje Foundation, which owns the hospital that the five of them work at. He has kept this secret from his friends for years (except for Seok-hyung, who has known him since childhood), until the events of the first episode lead him to reveal his background to them.
* Joon-wan, thoracic surgeon. He has a girlfriend with a major drinking problem, and they soon break up. Eventually it's revealed that he has a thing for Ik-joon's sister Ik-soon.

* GoodGirlsAvoidAbortion: Jae-hak and his wife find out in episode 2-10 that she is pregnant (unexpected as she's 40) and, at almost the same time, that she has breast cancer. The best thing to do for her health would be to terminate the pregnancy right away and start chemo immediately, but Jae-hak's wife refuses; keeping the baby will mean that they have to wait three weeks for chemotherapy. Justified in that the show had already revealed that Jae-hak and his wife had struggled for some years to conceive and eventually gave up.

* StepUpToTheMicrophone: InUniverse with the FiveManBand. Ik-joon sings lead most often, but Jung-won does sometimes, and Song-hwa insists on sometimes getting lead vocal even though she's not a very good singer. In the last song they sing in episode 1.12, all five of them take turns on lead vocal.

** In 2.10, Min-ha has done two straight night shifts and then washed her hair with soap instead of shampoo, so she's looking a little disheveled. She hopes that she won't see Seok-hyung, then thinks that maybe he's busy and she'll miss him that day. Naturally, Seok-hyung walks up almost as soon as the words are out of her mouth.

A second season premiered in June 2021. Song-hwa gently declines Ik-joon's romantic advances--but the plot thread continues to dangle. Seok-hyung's ex-wife, TheGhost in Season 1, shows up, complicating Chu Min-ha's hopes of a romantic relationship with her supervisor. Seok-hyung and Min-ha together deal with a complicated case involving a pregnant woman who still hopes to deliver her baby, despite the fact that her water just broke at a far-too-early 19 weeks. Jung-won keeps up a long-distance relationship with Ik-soon, who is studying in London.

* AnguishedDeclarationOfLove: Gyu-wool's confession of love of Jung-won in the first-season finale comes with stammering and copious tears, as she begs him to not become a priest but stay by her side instead. His answer? TheBigDamnKiss.

* RomanticRain: Song-hwa and Ik-joon briefly hold hands as they are trying to escape together after being caught in the rain in episode 2.9.
* RottenRockAndRoll: In episode 2.10 the doctors decide to take a break from K-pop and instead play a rock song. Hilariously, they all get special [[HellBentForLeather leather outfits]] for the occasion. Even funnier, the song they play is "It's My Life" by notorious death-metal band Music/BonJovi.
