After being dumped by his girlfriend of five years, and then things not going well at work... Dejected, Yuu throws everything away and visits a hot springs inn by himself. There he meets Kana, who is also staying alone. She says she hadn't gotten along with her husband and had run away from home. As they talk, Yuu and Kana grow closer, and before they know it, they're together... During their stay, they passionately seek each other out, as if to fill the void in each other's hearts, and as they press their heated bodies together after the bath, they are drowning in sweaty pleasure...
