Iori, a female doctor who visits patients' homes every day for home visits, has a gentle and gentle personality and is highly trusted by others. One day, a man's house called Yajima visited for medical treatment. Although I felt something extraordinary from the people around me, he was actually the head of the Yajima group. It was Iori who tried hard to treat Yajima who had a short life expectancy, but he was trapped by a yakuza who likes bondage and was confined.
