Plot
The show revolves around Isabella "Isa" Pasquali, a 15-year-old girl. Her dream is to gain the affection of Alejandro "Alex" Ruiz, but this proves to be a challenge, since her rival Cristina Ricalde has caught Alex's eye first. Isa's best friend is Linda Luna, who has the same dilemma that Isa has: she's in love with a boy named Reinaldo "Rey" Galán, who also has a crush on Cristina. Alex and Rey are rivals, competing against each other in a band contest. Rebeca Ricalde, Cristina's sister, is the rival of Marina Pasquali, Isa's sister. Marina is engaged to Cristóbal Silva, whom both Rebeca and Marina have fallen in love with. Rebecca has some advantage, since Cristóbal's mother, Lucrecia Portocarreros, supports her with selfish intentions. Cristóbal's brother Micky is Alex's best friend and plays the bass in Alex's band. His girlfriend Vanessa is a friend of Cristina. Alex's mother, Estela, is in love with her boss Julio Silva, but he is still in love with Jennifer Contreras, with whom he had a daughter when they were both teenagers. Isa's parents, Antonio and Carmina Pasquali, are owners of a pizza shop that is located outside of the building where many of the characters live. Eventually, Isa becomes Alex's girlfriend. She discovers that she is adopted and that her biological parents are Julio and Jennifer. Initially, Isa does not accept her biological parents, but ends up loving them. At the end of the series, Cristina becomes friendly with everyone and tries to reconcile with them. Linda and Rey become a couple, and Marina begins a romance with one of Isa's producers, Raul Clavati. Isa and Alex have their first kiss in the last episode, after several failed attempts throughout the series. == Episodes ==
