I don’t get this comic. The text is fine, but it has literally nothing to do with the characters or the coffee shop they’re in

I guess the story is that the blond girl had a previous conversation with the brunette pair about freaking out about the actions of humanity, followed up by days of silence, and then a tentative message to meet up in a coffee shop somewhere to discuss, or maybe she just bumped into them unplanned (hence the laptop?)

What is even the story here?
