Such a Treacherous Piano Sonata

Kanna works at a classical music office. She has never felt strongly about anything and her relationships with men never go well. However, the moment she hears the pianist Narisawa Gai play Rachmaninoff’s Sonata, she experiences intense feelings for the first time. Influenced by this, she embraces Gai while he’s playing piano! A classic love between a music manager and a genius pianist starts now!
