After rewatching a second time, I can confidently say that the FL and SML are two of the most unlikable, disagreeable, and unprofessional, and frankly, unethical characters I've seen. I disliked them both even more the second time through. I still rate this drama high because of the ML (who is frickin' amazing) and because it says some important things about mental health and self-acceptance but wow, they were terrible.

Here's the spoiler-y part:

Honestly I wish that Yong Shik would have ended up with Jennifer - she was an amazing friend and support all the way through. I just didn't buy Yong Shik's and Ru Da's love, (and I hardly ever say that. ) What the FL and SML did to Yong Shik in the beginning was so unethical and wrong that if there was any justice in the world they should have lost their medical licenses over it - I was just as incensed the second time about how they treated him. Also there are so few dramas that portray issues of trauma realistically and sensitively (and this isn't really one of them either, unfortunately,) but there were a few moments that shined. So all in all, it's a recommended-watch, but Dr. Do is an absolutely terrible example of a mental health professional!!
