Plot.
Roberto Villalva is an ambitious businessman who runs the technology company Redared. His attitude is that of a selfish young man who takes advantage of his social position to get what he wants. Suddenly, his life changes when, on his way to work, he is involved in a car crash that leaves him in a coma. While unconscious in the hospital, Roberto is taken to "La Muerte" represented by a voluptuous woman, who shows him an app called "DeathBook," which lists the people he had behaved rudely toward.
Roberto wants everything to return to normal, albeit with a different attitude than before the coma; however, "La Muerte" isn't sure if she wants to revive him. Later, the two make a deal in which, throughout the series, the young businessman will have to reincarnate as the people on the aforementioned list and also sacrifice one of his closest loved ones if he wants to live again.
