This is not a rom-com (which is what I normally look for), but a slow and serious (but not melodramatic) show about love. Song Hye Kyo and Park Bo Gum both did an excellent job. In most of the things I've seen Park Bo Gum in, there's always been something a little "off" to me about his acting. This role changed my mind. His acting in this was perfectly on point. When he was happy, you wanted to smile with him, and when he was unhappy it was heartbreaking. There was a slow buildup in their romance/love, and it made sense. His patience, and constant love for her was so wonderful to watch. I felt really drawn in to their relationship, sometimes I felt like I was a voyeur in their lives.

Park Bo Gum's character was open and innocent. He seemed to look at life with joie de vivre, and that was an infectious thing. I couldn't help but smile, watching him. His love for her was so apparent, even though they were so different. Song Hye Kyo's character, on the other hand, was very repressed. Her life had been decided and planned for her, and she had never deviated from that plan. I enjoyed watching him bring her out of herself, opening her to new experiences, and living the way she wanted to.

I did feel that the breakup, though necessary to keep the story moving, was a little lame, especially since it was uncalled for and none of the circumstances that she was concerned about changed, so the breakup made even less sense. I felt that Song Hye Kyo's character was a little too weak in standing up to her family (the moms in this were all nightmares!). I also felt that, because of her reasoning for the breakup, her love for him wasn't as strong, and that was disappointing.

The cinematography and the OST were both amazing as well. This show was beautiful to watch.
