I watched this for Gong Hyo Jin and found myself really liking Jo In Sung as well. There is a great chemistry with all the actors in this ensemble. The story is fresh (if a little laggy in some spots) and interesting. There's a bit of a mystery to work out with the main lead and his past, and a great twist in there. The leads did an excellent job. I like that neither of the two leads is "perfect". They are both broken people, and yet they find a way to love each other in spite of their internal struggles and pasts. Because GHJ's character is a psychiatrist, we get to see a little bit of her treating patients. While you may think this bit doesn't add to the story, each diagnosis we see helps her character understand a bit more about either herself or JIS's character and furthers their relationship. There will be some tears shed, but I think this was an enjoyable drama. Sung Dong Il can be annoyingly loud at times, but he still acts his scenes well. There is a bit of a secondary romance that goes on in this, but you'll have to be your own judge about how you feel about it. The relationships between the housemates and friends is a bit confusing at first, but sort of sorts itself out shortly. This story focuses a lot on mental health and humanizes people with mental health issues. This is a subject that I feel is very misunderstood by most people, so I like the way they handled this aspect of the show.
