I really don't get all the negative reviews here. I personally think this is one of the best dramas this year. Before the show even started we already know it's a Nam Joo Hyuk and Bae Suzy lead. So it's clear from the start that the story would revolve around them. The plot will favor them and NOT THE SECOND LEAD. I like Ji Pyeong but not for Dalmi. Like duh he doesn't really need to get the girl. He's a typical Kdrama character who is rich, handsome, superior with a good and bad side. While Do San has low self esteem, started from the bottom and made his way up.. and he did. Do San and Dalmi found what they are lacking in one another. In other words they inspire and COMPLEMENT each other. As a long time Kdrama watcher it's a breath of fresh air that childhood friends don't end up together. I've seen too much dramas that always have childhood connection. I mean, seriously how could she fall inlove with a penpal she never even met? Meeting Do San,getting to know him and falling inlove with him is more realistic for me. If some fans put their emotions aside they'd realize that this is one amazing drama. Learned so much from this drama and the OST's are so good.
