This was a great performance by joo won. I believed his character and if I dint know him well i would've thought he was autistic. The characters were well played but the focus was more on park shi won. His dad did a great job as a lousy father i hated him, vice president was a chameleon, the fellow doctors were good looking and the kids brought some life and fun to the story. the story also showed how koreans portray and deal with handicap. Its very scary thus lots of suicide. Anyways there wasnt much to the romance scenes. Just glimpses and a kiss. contrary to popular belief i dint cry at all. I felt sad for shi won but i was cheering him on silently. Oppa fighting!!!
