On the whole, this was an enjoyable, heartwarming show. My issue with the show is how the story basically plodded along. I could see from the outset what kind of story was aiming to tell and the tone it wanted to set. But because it was written to be heartwarming and lesson-teaching, there was little drama, and the story didn't have strong peaks and valleys. It became predictable and boring at times. Some relationships were not properly developed, so the way the relationships played out or were resolved by the end of the show were not very convincing to me. Joo Won is naturally the star of the show, since he plays an unconventional character in the Korean drama world. At times I was moved by his character, at others, I was frustrated. I particularly enjoyed Joo Sang Wook's character, Professor Kim. It's my first time watching Joo Sang Wook in a major role, and I think he put in a good performance. I can understand why he has previously been always cast in the CEO role. At times, the music was quite jarring.
