This drama is mindblowing and beautiful. The emotional road took the viewrs with it along with the charachters. The storyline, concept and everything about the drama was captivating..my goodness kim so hyun can sure make the viewrs cry and smile along with him.oh jung se did a very satisfying job acting like an autistic guy. The brotherhood btwn kim so hyun and oh jung se was soo emotional.the female lead did a great job too , at times drawing anger and empathy at other times..basically speaking this is a must watch before one dies
