It is one of the greatest series people should watch because it is educational, meaningful, funny, and based on hospital real situations..The five lead actors have different interesting personalities and stories that captivates the audience. E.g. I am fascinated with the bluntness of doc Kim Juwan with his patients' guardians but humurous whenever with friends. Doc Lee Ik Jun is funny and fun with his cute son. Doc Song Hwa, being a woman in the group is very appropriate and decent..and also the other two doctors have their own distinctive traits. In addition, they have their own expertise that made them extraordinary doctors. What I enjoy most is whenever they are together eating and teasing each other and most especially their band. I super ❤️ 😍 💖 ❣️ 💕 love their music performances..Amazing and cool..
