You're died because of accident, and now you lived in a place where immortal souls are there after death

But despite you already died, you still want to live again. But there's a condition, where you'll paired with someone as human too

You paired with Jasper. Not as lover, but more like He dies, you die. You die, he dies. So one of you shouldn't die too fast, so your partner can live longer

Now you both placed in a different places on Earth, not knowing each other. Just FEELINGS
