In addition to being the orphan of both parents, Marta suffers from a severe form of cystic fibrosis, which could kill her very soon since the treatments she is undergoing are not working.

Arturo feels guilty, so the next day he shows up at her workplace and asks her for a real date, this time taking her to a fancy restaurant where he usually goes with his family.

Marta's doctor informs her that her mistake has accelerated the process and that she has very little life left: the girl is discharged and confronts Arturo, but she pretends not to be in love with him and that she has decided to leave him because of this.

But when she sees Marta leaving the pneumatology department, Beatrice buries the hatchet and reveals exactly what happened the night before, finally convincing her to tell Arturo everything.

The next day, Arturo runs to Marta and reveals that he has discovered a new experimental cure for her illness, which would give her a 19% chance of survival.

The boy finally agrees to fulfill another of his fixations: staging his wedding, among other things inviting everyone close to him to the fake ceremony.
