Despite the uncertainty surrounding Shinichi Chiaki's relationship with eccentric pianist Megumi "Nodame" Noda, most would assume it is a romantic one—especially Nodame herself, who has professed her love for Chiaki on many occasions. But when a petty quarrel over soy sauce leads Nodame to gratuitously accept a date invitation from Lucas Beaudry, a young French piano prodigy, the highly acclaimed conductor Chiaki experiences true jealousy for the first time in his life.

Nodame Cantabile Finale OVA is an anime-original story written by the manga author, Ninomiya Tomoko, herself. Unlike regular Nodame Cantabile episodes and OVAs, this anime special does not have a title, and it never aired on television; however, it was bundled with the limited-edition copy of the 24th manga volume—the first volume of the sequel manga Nodame Cantabile Encore: Opera-Hen—as an original disc animation.
