I Open a Brothel in Kyoto

The male protagonist of the novel accidentally traveled to ancient times and thought he was having an erotic dream. At the beginning, he had to go hard on the eldest lady, but one of his hands was cut off. Later, he unfortunately contracted a sexually transmitted disease. He had no money to see a doctor, so he could only cure the disease by selling his feelings about touching the eldest lady's body. Since the eldest lady was famous in Kyoto, people came and went in an endless stream. He used this to implement his plan to open a brothel, because he had no advantages since he was a child, only specialties, and he had good kidneys.
