Through Korean dramas, I have gotten to see many many kinds of professions. I have seen dramas that depict the medical profession (Good Doctor, Beautiful Mind, A Poem a Day etc), the legal profession (Money Flower, My Lawyer, Mr. Joe etc) and also, several other kinds of professions, including part-time ones.
I am myself a software developer by profession. Before watching these dramas, I used to be only interested in my work. But now, I actively study and take interest in other fields/professions too. It has really made me appreciate the challenges and responsibilities people in these fields bear, especially the medical and the law professionals.
