"Your housekeeping skills are 20 points. And as a wife, you're a zero."

Since Saki married her husband, Naoya, he's completely changed. He's become a manipulative man who constantly judges and "scores" her. But for the sake of her daughter, Saki puts up with his controlling behavior.

To rub salt in the wound, Naoya praises their neighbor, Madoka, as a "100-point woman." When Saki discovers he's having an affair with her, she sets out to get revenge on her toxic husband and his arrogant mistress!
