I was a surgery resident and now work in biotech. My postdoc research was at Stanford for cardiac cell therapy. I just ignored medical issues and watch it. Haha...... who cares about medicine when you watch K drama. Like you said, that is not the point. Korean drama has all the formula and it still gets the audience every time because those elements work. Medical issues are not the issue here. We still watch it. Face palm.......... we all believe in true love deep down. It is the Disney effect. Never never gets old.
