I'm looking for a movie I've watched a couple years ago. I don't remember a lot of the movie and I forgot the name of it, but I hope someone can help me to find it.
First of all I'm not even sure if it was a Korean movie it could be a Japanese movie, but I guess it was Korean.
I only know that it is about two men who are in prison. They are falling in love with each other (I'm not sure about this). The prison guards are quite violent, also the people in prison. It could be that there was something with a butterfly, which I'm also not sure about.
The film had a strange atmosphere.
I know the description is not very usefull because I forgot a lot about te movie, but I hope some of you will recognize something and will be able to help me.
