I get why this is a Kdrama classic, it's original, the story actually has a plot and it was well developed in 20 episodes. I believe that watching this in 2024 will make you question how the male lead treats the female lead in some occasions, but just get that this was 11 years ago, so obviously we have evolved in humor (for the better) since.

Kim Soo Hyun get's to sing some of the OST, which I find beautifully performed in some of the last episodes. Give it a try if you want to find out why this was such a hit in Korea.
