Yuki decided to live in her husband's parents' house as her husband, Yuichi, took over the family's company. Her mother-in-law, Ikumi, doted on Yuichi, and was strongly against Yuki. Still, my father-in-law Taro was lusting for the appearance of Yuki who devotedly supported Yuichi. Then, one day, Yuichi and Ikumi weren't there, and Taro, who was alone with Yuki, pushed Kayuki down. After that, Yuki was afraid of Taro and avoided him, but Taro toyed with Yuki's body everywhere despite Ikumi's presence.
