This series exceeded all my expectations. I felt a whole spectrum of emotions during the course of the series. Joy, sadness, excitement, learning, love. The acting of Tang Joon-sang were incredible and very convinsing.
For someone who has people on the autism spectrum around me (in Sweden we have chosen not to use the word Asperberger's syndrome anymore) this series is so incredibly apt in what it is like to be a loved one. I can't recommend enough to everyone to check out this series, it just have to be watched.
