Sisters Ai and Hikaru, who lost their mother, lived with their father who ran an inn, but due to hardships, their father was hospitalized. Her sister, who is at a loss, decides to manage things with her sisters. However, the customer who came was a businessman from whom her father borrowed business funds, which had been a source of worry for her father. They set their sights on the sisters and deceive her younger sister Hikaru and take advantage of her body... I showed the video of that scene to my sister Ai.
