Until the 2010s, Fermí Casado was primarily an actor recognized for his work in series such as Estació d'enllaç, Mar de fons, and El cor de la ciutat. He rose to fame by playing the character of Tomàs, the fictional son of Àngels Poch and Josep Maria Pou in that popular TV3 fiction set in a Barcelona train station. From then on, Casado continued to string together theater performances and television projects, through which he built a solid acting career alongside directors such as Mario Gas, Sergi Belbel, Joan Lluís Bozzo, and Roser Batalla.
