I looked forward to watching PAIN because it paired Jung Ryeo-Won & Kwon Sang-Woo & neither actor disappointed me. Their performances were both powerful & believable. I've already recommended this film to my friends. The story, acting & music were all solid 9s for me. I didn't give it a 10, but only for its rewatch value. Rewatching this movie would be like rewatching AUTUMN TALE: too emotionally draining and so sad.
