Against the wishes and advice of friends and relatives, Chul-soo and Young-hui get married. They start their life together but because of their inability to communicate, their marriage falls apart and ends in divorce. Friends help them find a two-story house to live in. Chul soo takes the upstairs and Young-hui, the downstairs. From that moment there is constant interference and jealousy between the two. Young-hui eventually brings a man home to make Chul-soo jealous, which it does, even though he no longer has right to interfere in her life.
