○ Ryoko lost her parents in an accident when she was young. It was the Hojo family who took in Ryoko, who had no relatives, as an adopted daughter. My parents-in-law are very kind people, and Maki, my sister-in-law, also loved Ryoko like a real younger sister. One day, several years later, Ryoko, who had grown up and started living alone, received a phone call. It was from the divorced Maki. That night, Maki, who came to stay, suddenly touched Ryoko's body with a completely different atmosphere from when they lived together.
