Honestly I've watched a lot of movies and dramas but this has been one of the best movies I've ever seen. Definitely a #1 or #2 for me due to it's heart-warming story. The story is about forgiveness and understanding. The two characters meet under unique circumstances and initially don't seem to get along. Yet, there's something each of them holds that can help the other. The lead female is a psychology major and the male lead is a criminal. Of course, she can help him in the obvious way: make him reflect on his mistakes and change his ways to lead a new life. But that would make for a simple and plot, so there's something more... There's something he doesn't know he can help her with until she shares her story. The misunderstandings they have of each other clear up and he wants to do whatever he can to help her as well. The way each character develops is what keeps you watching. The acting is great! The cast members each do an excellent job portraying their characters - esp Dong Won and Na Young. They will have you bawling by the end of it but you will love it - especially if you like tear-jerkers. I watched this movie when I first started watching Korean dramas back in 2007 an I've re-watched it over a couple times and still don't mind re-watching it with people who haven't seen it. It's a movie that does NOT lose it's re-watch value.
