Un professore

Dante Balestra is the new philosophy teacher at the Leonardo da Vinci scientific high school in Rome, where he has returned after an eight-year absence to be with his son, Simone, now that Floriana, his ex-wife, is moving to Glasgow. Charming and unconventional, the professor takes a class at the Leonardo Da Vinci High School where he applies his non-conformist teaching method and establishes a very special relationship with his pupils, including Simone himself. But his manner soon leads to confusing private life with professional life, and the return from the past of Anita, an old acquaintance of his and mother of Manuel, the 'black sheep' of the class, makes things even more complicated.

Professor Dante Balestra is now an indispensable presence in the lives of his students, among whom is his son Simone. The beating heart of the series remains the Leonardo Da Vinci high school with the class attended by Simone and Manuel (Anita's son) where Dante, with his usual non-conformist and ingenious flair, uses philosophy to help the boys solve their problems, including complicated love affairs, intrusive parents, daydreams and dashed hopes.

New class members appear in this season, such as Nina, a girl of Polish origin who hides a complicated life path, Rayan, a promising footballer who has arrived from Africa and is more interested in football than in studying, Viola, a disabled girl with an impossible character, and finally Mimmo, a former student of Dante's who ended up in juvenile prison, whom the professor has managed to get committed to the Leonardo da Vinci library in semi-freedom.

In the finale of the first season, because of a photo Simone found, he is forced to reveal a shocking secret to his son: Simone had a twin brother, Jacopo, who died of meningitis at the age of three. Despite an initial furious reaction from Simone, the two manage to reconcile. In the course of the second season, he has to face not only various problems in his private life, but also a serious health problem caused by an arterio-venous malformation.

Here he will meet Simone and defend him from a homophobic attack. Over time, they will form a deep relationship, partly because of a complicated situation they will face together that puts Mimmo's safety at risk. From this relationship, the two boys will fall in love and start a relationship. In exchange for his protection, Molosso will force Mimmo to work for him, first by making him collect the payoff and then by involving him in a plan to assassinate a man. Terrified, Mimmo, spurred on by Simone, will decide to cooperate with justice, denouncing Molosso and his henchmen.

Although partly based on the Catalan series, the Italian version has several differences from the original:

• In Merlí, Pol lives with his father and brother Oscar at his grandmother's house. Manuel, Pol's Italian counterpart, lives instead with his mother Anita, while Pol's mother died several years ago at the beginning of Merlí.
• In the Italian version Dante and Anita starts a relationship, this doesn't happen in the Catalan version. For the same reason, in the Catalan version the arc of Pol living at Merlí's house doesn't exist, different from the Italian version with Manuel and Anita living at Dante's house.
• In Merlí's series finale, through a time skip, Pol and Bruno get married. In Un Professore, the relationship between Simone, Bruno's Italian counterpart, and Manuel becomes one of deep friendship, tending to brotherhood, and mutual support.^[7][8]
• In the Catalan series, Pol explores his bisexuality. In the Italian series, this isn't represented with his counterpart Manuel rather with Mimmo.
• Nicola's character exists also in the Catalan version. He is the Italian man which Bruno, Simone's Catalan counterpart, met during summer in Rome, and which he lives together with at the end of season two. Broadly speaking, this character's italian counterpart is the character of Mimmo.
• In the Catalan series Pol and Bruno part ways for a while due to Pol's leaving to Tokyo with his father. In the Italian series Simone and Mimmo are the ones who part ways due to Mimmo's entering the witness protection programme.
• Luna and Laura's characters are partly inspired by Tania Illa, Bruno's best friend. In Un professore, Luna takes Tania's personality while Laura her aspect and Simone's friendship (relationship before Simone's coming out). Luna is in love with Matteo, based on Marc Vilaseca's character, exactly like Tania.
• Aureliano, Monica and Giulio's love triangle is examined in depth in the Catalan version with, respectively, Joan, Monica and Gerard's character but with the boy's roles reversed. Although Joan shares Giulio's family situation, he's the one who interposes between Monica and Gerard (like Aureliano does) and eventually starts a relationship with Monica. Gerard is Gina's son, a parent representative which starts a relationship with Merlí, exactly like it happens with Dante and Cecilia, Aureliano's mother, in the Italian series. Always in the latter, all these characters do not appear in the second season.
• Pin, the guy who suffers from agoraphobia due to the bullying he went through, is inspired by Ivan. He appears only in season one.
• In season one finale Chicca goes to another school to chase his artistic talent. This doesn't happen to her Spanish counterpart, Berta. Furthermore, is Berta who pretends to be pregnant when Pol leaves her. In the Italian series, Laura is the one who pretends it when she's dumped by Simone, which is Bruno's Italian counterpart not Pol's.
• Nina is inspired by the character of Oksana. The latter, however, unlike Nina to whom her daughter Lilli is taken away by social services, raises her son Nil herself together with her parents. Moreover, if Nina embarks on a relationship with Manuel, Oksana will instead become engaged to Pol's brother Oscar.
