Two years into my marriage, I felt happy despite our ordinary life... That is, until I met her... After our marriage, my wife quit her job to become a full-time housewife. One day, she decided to have a drinking session at home with her former boss. Her ex-boss is a single mother who's also a capable career woman, a wonderful mother who cherishes her only son. But this seemingly perfect woman transforms into a seductive temptress whenever her son isn't around... "You and your husband must love each other dearly, right, Manami?" "Of course..." "But... isn't your body a separate entity? As long as it doesn't get discovered, it's not cheating, is it?" "But..." "Can you really bear to endure for years with just Manami?" Is there a man out there who could resist such an invitation and remain faithful?
