Rina Kosaka is a renowned international violinist. As a student attending Rina's violin lessons, I became captivated by her beautiful, graceful playing and her strikingly fair, translucent appearance, which drew me to keep coming back for lessons. She is incredibly kind and always gives careful, patient instruction, yet my violin skills barely improve, making each lesson a constant struggle. Amid this, an undeniable, special tension begins to grow between us—going beyond a simple teacher-student relationship—and deep inside, I can't stop fantasizing about intimate moments with her.
