I don't think they are getting punished anymore. Maylene is going to work alongside Nullitas as she has already given Maylene a second chance after one, seeing how far she has come to become a better person and two, being the only family left alongside her sister's mother to be alive. She valued family and made her peace with the past and decided to work with Maylene.
I know Nullitas' mother is alive and same with the King too but I was mainly talking about anyone else from the Romangolo family sense the head and brother are now dead. She literally has no one else so she has a sister and brother to have in her life.
The step mom literally became addicted to drugs and probably didn't live for very long after Avio died. Idk how that's getting off easy. I mean yeah, she didn't exact revenge on her personally but the step mom definitely got what she had coming
The stepmother was actually still alive despite everything that has happened to her. Maylene saved her mother from the brink of death.
The step mother and step sister got away so easily when they're the ones who greatly contributed to the fl suffering. I was hoping more punishment from them, i guess development is more important in this story.
