This is my favorite drama of all time. It has everything, it's happy, it's sad, it's frustrating and it makes you mad, but in the end it's all worth it. Jang Hyuk plays the eccentric male lead perfectly, he's childish, annoying, mean and then his character develops and you find him handsome, noble and sweet. He is one of my favorite actors and it helps that he is hot, hot, hot. Jan Na Ra is amazing as the female lead, some will think she is weak, that she lets the ML walk all over her, but what she does she does for love and the love of their unborn child. Yes, the story does contain the usual tropes like amnesia, the ex-girlfriend and a hereditary disease but it all adds to the drama and never gets boring. I didn't skip any of this amazing drama. In all honesty I re-watch this drama after a heavy drama and then decide what I am going to watch next. Do yourself a big favor and watch this drama.
