After Marioni assigns the orchestra parts to play with the guest conductor, there are some moments of tension between Matteo and Nathan. As a few students gather outside the conservatory, they see Giacomo, an ex-student.

Marioni manages to reach Giacomo to tell him that he's sorry for how things turned out but also to encourage him to move on with his life. Matteo goes to talk to the new psychologist but puts up his defenses by saying that he doesn't talk much.

After the meeting with the psychologist, Matteo meets up with his uncle, who invites him out for un aperitivo (a drink). At the pub, Matteo teases his uncle because the waiter happens to be an ex-boyfriend of his.

When Marioni gets home, he finds Irene waiting for him in her car. She knows Giacomo had shown up at school. The next morning, there is a rehearsal of the orchestra, followed by the Mozart sonata for two pianos, played by Barbara and Domenico.

Maestro Marioni listens to Domenico and Barbara play and is very harsh in his criticism of the girl's playing. Despite her friends being supportive of her, Barbara decides to go home to study instead of going out after the rehearsal.

Sara goes to talk to Gigi, who is playing his guitar and singing on the street. When Robbo returns home, he finds Chiara upset, who tells him she's gotten into trouble. Barbara, on the other hand, has to face Marioni again at the orchestra rehearsal.

During the concert rehearsals, Marioni believes that Barbara hasn't put in enough effort because she has dedicated time to studying philosophy. He therefore decides to exclude her and warns the others not to console her.

Matteo and his uncle Daniele seem to be very similar in some ways, but perhaps Matteo shouldn't be copying his uncle in every way. Scheggia and Sofia go to eat at their mother's restaurant and tease her a bit.

Matteo meets Sofia to whom he confesses being excited about the concert. At Sara's house, Gigi plays for her parents the song he composed for her. Robbo and Chiara unfortunately witness an argument between their parents.

Marioni is summoned by the principal because he received a warning from Giacomo's parents who hold him responsible for what happened to their son. During rehearsals, the maestro discovers someone who shouldn't be in the hall.

Maria Inglese, an Italo-German artist, sings a famous song by Lucio Dalla, dedicated to the Neapolitan opera singer Enrico Caruso. Even though the song uses ti voglio bene, the generally less romantic version of "I love you," it was likely meant romantically here, as Caruso had fallen in love with and married a younger woman shortly before his death.
