It was entertaining from beginning to end with good chemistry between the characters. I loved the attention to detail as a medical series and the maturity in conversation of the main characters. There was no โoh my gawd can this pleeease just endโ feeling that I get from some of the other kdramas Iโve watched. There were several flashbacks but they werenโt excessive, rather, they added to the storyline not just as scene fillers. Just finished watching it and I want to watch it again. For a 20 episode drama, I felt I could still watch more.
