Ever since childhood, Kyoka has been aware of her hidden masochistic desires. Raised in a wealthy household under strict discipline, she always felt she was different from others. Now 22 years old and a graduate student, her pen name is ○. Growing up in an oppressive environment, she unconsciously developed a longing for master-servant dynamics. To fulfill this desire, she met her current Master through the personal ads section of an SM magazine, finally establishing the dominant-submissive relationship she craved. In the past, she experienced rough sex with a regular boyfriend, which was when she first realized she was a masochist—an experience that ultimately led her to her current Master. Captivated by his dominant demeanor, she completely surrendered herself to his control. Now, she obediently follows his commands, living each day in pursuit of pleasure under his rule.
