In this universe Stray Kids are a group who live on the streets, sustaining themselves through working part-time at a factory and pickpocketing in the crowds. Though they do get caught occasionally, they live a relatively peaceful life.
But slowly, gradually, people start to disappear, and their corpses turn up again days later, horribly mutilated. They say it is the work of ghosts, and as the rumours increase so do the casualties until finally, all the world leaders disappear and the world springs into chaos.
Stray Kids manage to get to the underground bunkers on time, but Han suddenly disappears and turns up days later, mutilated but alive. With that what people are left drive them out to the apocalyptic world to fend for themselves.
(This story I first thought up of when I first watched Scars and so the context only centres around what I interpret from the MV, so this may have nothing to do with the Stray Kids storyline)
