In addition to delving into the teacher's private situations, the series also focused on some students such as Gabriela (Diana Ángel), Magdalena (Verónica Orozco), Elkin (Manuel José Chávez), Carlos (Óscar Mauricio Rodríguez), Marcela (Lina María Luna), Fernando (Jorge Monterrosa), Jhonatan (Jacques Toukhmanian), among others.

Inside the school, he met his co-worker named Adriana (Alejandra Borrero) with whom they would make a friendship that would last until Francisco Restrepo left the series.

The intention of the series was to awaken and raise awareness about the most common problems of Colombian youth, so that new generations understand these situations and can travel the right path in their personal lives.
