Kim Byung Chul was exceptional in this role -- he definitely brought it home and MADE THIS SHOW. I so much disliked his character, such a prick! In general, Dr. Cha was a hard watch, very real. I think that's been its success. The show did have some very touching scenes and reminded us how complicated relationships can be. So glad I watched it 'til the end!
I understand that there are many episodes left yet HM is out of control -- too much airtime spent on her -- I wish the writers would focus on the leads or other characters! I've been skipping episodes due to HM's non-realistic character. In a real work environment, she would have already been fired!
