I went into this without really reading much about it - it was recommended by many people on my feed, for numerous reasons - so I had to get it watched, clearly. Once I got started, I had to continue, and have basically ended up watching the entire thing in one sitting. :)

First major thing I noticed is that while this is a somewhat-medical drama, it focuses on a branch of medicine that is rarely covered anywhere - Psychiatry. Dealing with a range of characters that have a variety of different challenges to face in their lives, getting help is a key part of the message. You're never alone, no matter what, you can always ask for help, and the amazing people in Psychiatry are the ones to provide it.

The pacing on this one is absolutely perfect. The main lead couple is amazing, the chemistry between them is spot on. They have their disagreements and even misunderstandings - but there's not a stupid breakup in sight. They solve their problems by talking to each other, being straight forward and honest. On the one or two occasions they don't, a character is nearby to smack them upside the head and get them to deal with it right away and be honest. It was refreshing and allowed the author time to go into other more interesting areas.

One of the second couples - which had Lee Sung Kyung (whom I seem to be watching an awful lot of lately) was really good too, showed some good development in both the characters particularly hers as she moves from school girl to young woman and decides what she wants out of life.

Various mental issues are covered but primarily the topic of the show is the highly misunderstood Schizophrenia (which is NOT the same as Multiple Personality Disorder). Much like any medical drama, various patients will come by our characters and their stories will unfold over two or three episodes as the doctors help them to work through problems and open up their emotions.

There's a large message throughout this story about clearing up misunderstandings about mental illness and how Psychiatrists can help. One of the characters has Tourette's Syndrome and there's an exceptionally touching moment when Lee Sung Kyoung's character kisses him first - something that always triggers an attack - and where you're expecting the youthful and barely mature girl to freak out at what looks like a "eww" type response, she places her headphones on his head with some soft music and holds him - and he calms down in no time.

Haven't listened to the OST yet but the music throughout sounded great so I'm looking forward to having a proper listen.

Overall, I can only recommend this as something that must be on your "must watch" list somewhere near the top.
