A sad yet lovely romance drama that revolve two person. Both of them faces through many difficulties before they can get together. I got to said that the two actors who portrayed as young Soo wan and Dong jun did a great job that kept me to keep watching this drama. Sang yoon who has a sweet and angelic smile never fail to make me smile whenever I see him.
