Per @pizzakissingpizza:
I don’t think it’s common, no. So, already a long shot, made longer by the fact that most likely, Jacobo/Leon will not survive the ending. And he is very much the center of the show and one of the big attractions in the cast.
There’s no such thing as seasons in Latin American telenovelas. At most, there might be a sequel but it’s only happened like a handful of times, at least in Mexico. Amar a Muerte has an 80-episode order and they already finished filming so it’s gonna be definitely over for good.
