This drama is neither medically challenging one nor romantically attractive one.
First half of the drama it is portrayed the ML as a big trashy jerk, and in the second half of the drama the FL is fickle minded.
In the first episode ML and FL got married and got divorced due to mismatch in lots of things, ok it’s understandable that they did mistake by rushing for marriage but after got divorced they start to cursing with each other especially the ML in a very disappointing way, that to once they loved soo deeply, I felt it’s too unrealistic.
In the starting of the drama ML insults FL in a very unacceptable way, he scold to FL (ex-wife) number of times that she sell her body, kisses etc etc to get a favour from higher ups. How can a ex-husband can tell to someone once he loved so much and got married also.
Fickle FL, when she decided to start a new life with someone and start to develop feelings on chief and giving signal that he is more than just a mentor or supervisor but when the ML father died again she got her feeling back on ML. Poor chief who still had feelings for his ex-girlfriend got over(she was waiting or ready to accept him) to develop feelings on FL, even though FL knew that the second ML(chief) has feelings for her she keeps on stirring his feelings and giving wrong signal(according to ending) to him and SML keeps on stirring the feelings of SFL by showing to SML about his helplessness and love towards the FL. This is only Kdrama I saw such cruel towards SML and SFL. Most cruel one is when he decided to confess his feelings to the FL he witnessed her kissing the ML, ? too cruel.
When ML realized that because of him she hurt, suffered and suffering a lot he told to FL to start a new life with some one with whom she loves, but instead of vanishing from her life( he had qualification, money and everything so that he can also start a new life) he keeps on nagging with her by simply showing he is maintaining some distance with her.
Most of the drama is filled with medical cases but I didn’t seen any such challenging cases or surgeries. All the cases were solved in ER itself, its soo immature.
