Chiaki rehearses for his debut concert in Paris, and finds that Nodame is troubled as she is not doing fine at the conservatoire. While he tries to cheer her up, their relationship ends up moving a little forward.

Kuroki was having trouble to adapt himself to life at Paris until he meets Nodame at the conservatoire. Meanwhile, Chiaki is feeling insecure as Nodame does not answer his phone calls and wonders if both will really be able to spend Christmas together.

Chiaki is appointed as the official conductor of a famous orchestra which is facing serious dificulties, and Son Rui, a famous pianist who is an old friend of his, gives a break on her performances to study at the conservatoire. However, Rui's closeness to Chiaki is more than enough to ignite Nodame's jealousy.

The Marlet Orchestra is short on staff, and Chiaki asks Nodame to take a part on it. However, Nodame's dreams of having her first performance along Chiaki are crushed when Rui is forced to assume her place due to a misunderstanding.

Disappointed with his first performance, Chiaki starts scouting for new musicians and invites Kuroki for an audition. Meanwhile, Rui is forced by her mother, Mrs. Son, to leave Paris with her, after she heard from Madame Bellou (possibly Rui's landlady) that she's been slacking off and spending time at Chaiki's. While Nodame rehearses for the exams at the conservatoire along with Kuroki and Paul duBois.

Nodame travels to Saint-Malo with Chiaki, Tanya and Kuroki for her very first recital. However, her companions are worried about her insecurity, as she usually has trouble in playing pieces by Mozart.

Nodame's first recital becomes a huge success, to the point of her receiving other proposals for job.

Auditions are held for the Marlet Orchestra, with Paul and Kuroki being among the new members. After intense rehearsal, the Orchestra has another concert, and the time comes for Chiaki to show the results of his ad his musicians' efforts so far.
