Solid relationship drama that towards the end becomes something else entirely. I wasn't expecting the change of tone but I still thoroughly enjoyed the film. Good performance by Choi Min-sik and impressive directorial debut by Jung Ji-woo who would later on direct one of my all time favorite films, 'EunGyo'.
I thought that this was a story about the difference between married love and passionate all consuming love. It's clear that the married couple have little passion while the wife's former boyfriend and clandestine lover offers the spark of passion that is missing from the humdrum of married life. Jeon Do-yeon is incredibly sexy and the love scenes are incredibly hot.
