Rei Kuroshima plays an adult music student who spends every day practicing violin for conservatory admission. Her strict parents impose an early curfew, and endless practice is driving her mad with frustration. Her mother hires a 48-year-old music instructor to tutor her at home until she passes the entrance exam. As he stands behind her and touches her body during violin practice, her suppressed desire surges. “Teacher... I want to kiss you.” From that day on, every lesson at home ends with her asking him for sex. “I want more with you.” Soon, music no longer matters to her at all.
