I really liked this movie, it had unusal characters which work surprisingly well with the storyline. Cha Tae Hyeon, as one of my favorite actors, was great as usual, he gave his character such presence. It was sad how things turned out and I cried quite a bit. Definitely worth watching!
If you are in a low, this is THE movie to watch to brighten your life. I don't know how many times I have rewatched this movie, it's definitely one of my alltime favorites.
