This is, hands down, one of the best shows (not only amongst kdramas) I've ever seen. The acting was absolutely incredible, the plot was, in my opinion, very well thought out and the show as a whole was extremely heartwarming and moving. It was so refreshing to see this kind of thing in kdrama and I think, that all those mental illnesses and all the struggles the characters went through, were represented in an accurate way and were handled correctly. I have nothing bad to say about it and I urge everyone to watch it too.
