Although the speculative element was a little too dim for my tastes, something here drew my attention. In Brazil, we have Yellow September--a campaign to raise the population's awareness about depression and suicide prevention. It’s amazing how it fits here!
Also, there’s this scene in particular: they buy food and alcohol to make a “feast”, they have it, then they wake up sad the next day. It was just a palliative. It reminded of the movie Druk, aka One More Round (2020). People are always looking for things to make them move further in life. They’re always addicted to something.
