Marina (temporary name) is a 43-year-old woman with no marriage or children, working as a hostess. During her student years, she lived up to her parents' expectations, always maintaining top grades and showing little interest in romance. As an adult, she continued striving hard, determined not to fall behind her male coworkers. The first time she was ever confessed to was at age 24; although the relationship progressed, it never led to marriage. In later relationships, she gave too much of herself, making her partners feel overwhelmed, ultimately leading to breakups. Since her late thirties, she has worked at a mature cabaret, accumulating various romantic experiences. Now, completely opposite to her younger self, she has begun to take pleasure in romance. From the very moment she arrives at the inn and raises a toast, she transforms into a woman who willingly surrenders her body to desire. Bound by just a tied hand, her eyes moisten and her body trembles with anticipation, spending the entire night immersed in passionate, unrestrained love.
