The only people in this world

This idea came to me while I was doing work and listening to " lemons " cause lemons sounds like " I'm the only person in this world " song so-
This ships in this story are: iwaoi, sakuatsu, and ushiten
So pretty much it's about iwaizumi and oikawa they think they are the only ones on earth after everyone disappeared 2 years ago. But then they meet sakusa, atsumu, tendou, and ushijima. They are trying to figure out how this happened and they think someone is watching them. That's it- it's gonna be a short story since I'm writing one shots and I have school 👏 anyways that's it
There might be smut and some angst but other than that that's it-
I dont own the characters!!!!
And yes this is mostly iwaoi so-
