The reason why many people step into the massage parlor where Kozai works is not only because she has gentle hands with many years of experience in the profession, but also because they have another desire to have sex with this beautiful female massage staff. But she is not an easy woman, before serving customers, she was harassed by the manager, refused, and he raped her despite her crying and begging, but he did not stop and even had more intense sex. After that incident, her personality completely changed, instead of being reserved as before, now she is more easy-going, comfortable in her work, even when customers have not requested anything, she actively "serves" them enthusiastically.
