Mariko, a seemingly normal housewife, has been together with her younger husband named Tomoharu for six years and has been dissatisfied every day. Despite having a son together, Tomoharu is often absent from home and she suspects he might be having an affair. Her workplace, a batting center, is also a miserable environment because the sleazy manager chases after her and the customers are rude. With constant pressure bearing down on her in public and private, Mariko becomes dominated by a certain obsession that eats away at her perception of reality.

Kato, a scriptwriter, is in love with Miho—but he can never manage to muster up enough courage to make the relationship anything more than a platonic friendship.

She's in love with someone else, it turns out, but Kato swallows his pride—hearing about it all is almost too much to bear, but he wants to be with Miho as much as he can.
