On a midsummer afternoon when the record-breaking heat continued and the sweat didn't stop, my brother's wife, Kyou, who was in trouble because the bath at her brother's house broke down, came to rent a bath at my parents' house. Alone with Kyou after taking a bath under one roof, her chest was throbbing. One day, as usual, when I look into Kyou's bathing figure through the frosted glass, my eyes meet. I turned my eyes and returned to the room, but I wondered if there was Kyou with a bewitching smile.
