im looking for a oneshot or short manga, the premise was that a meteor was going to hit earth and the world was doomed. the main character's parents ranoff/disappeared and she bonds with other girl and they spend time together until the earth is destroyed, i think in the end its implied they meet in the afterlife, there was also a scene where humanity launchs a missile at the meteor but it doesnt work.

With overwhelming certainty Just Like This, Until The World Ends.

There's also To You Who Were Buried which has the moon slowly falling towards earth, but there's no implied afterlife ... if you ignore the zombies.
