The protagonist of the game is an ordinary Japanese man who lives together with his pretty wife Harunako. Two years after their marriage, they decided to move into a mansion in the suburbs. Everything seems normal when the couple arrives. But very quickly they both become involved in sexual intrigues, and witness strange events - mostly of sexual nature - that occur in the presence of their neighbors. Looks like the quiet family life they were hoping for will never become reality...
