I watched a movie from Cha Seung entitled Man on High Heels and he is really a different person in this movie.
I cried a lot at the end of the movie, especially to watch the excellent chemistry with all my favorite actors and Um Chae-Young. Um Chae-Young is also great in this movie as the sick daughter. SHe was a bit disappointed at first when she met her mentally handicapped father but after spending time with him when she sneaked out of the Hospital to get an autograph, they was able to interact with each other.
In the middle of the film, we find out that it was an accident while working that left his father mentally disabled.
This movie is worth to watch too
