Arrival

5 people, taken right after their moment of death, cured of their fatal injuries and illnesses. They're happy to see each other, happy to be alive, but don't understand where they are or what's happened to them. There's this weird box in the corner of the room though, so... maybe that's their answer?

Before they can open it, 4 new people charge in- 2 pairs, 1 familiar and the other unfamiliar. Though there's hostility, it seems that love can overcome it for now, and both are welcomed.

Then the box whirls to life. It casts a bright light before them, and 3 words form in clear lettering.

"8 Years Later".
