maybe this drama is one of drama that I don't know how to criticize?

simple drama with simple medical story, even have a continuous season, but they complete the story and problem every season

maybe the only one problem is , the distance between season 1 and season 2 too far? 2017 2020 ,far enough to forget some figures mentioned ,chairman shin, his daughter, his secretary, the doctor who nurse park like before

and i think there might be season 3? and if so I hope not too long
