From all the series about medicine this drama is definitely the worst one. All 3 lead characters are completely annoying.

Kang dong-ju is a hypocrite. Also he is angry and arrogant just because someone is a better specialist. So instead of admitting that he made a mistake he is complaining about a Teacher Kim.

Female lead keeps blaming others about her situation from the past.

Teacher Kim - no comment... (in a negative way)
